Buying a modern Intel server c NVMe P4800X
September 17th, bought for personal use server value 7680$ provider-a Tisk.
Set in the Moscow data center tech.ru and commenced operation.
Photo report available. The article consists of 5 parts:
the
In August 2015 successfully formed the circumstances, so I started to do online game.
I had quite a large selection of unfinished what to do. For a number of reasons chose online the game.
Started to do it and for half a year of hard work made good progress, but then the savings ran out. Nevertheless, I went very far in this matter and then continued to Refine the online game in their spare time. The game requires a lot of server resources for the rating calculation.
I had 10 years a personal server in Kiev data center hvosting.ua. He got me by chance: "I Want a server like that, that's 750евро and pay only for rack space?", well, I then once again had an extra 750 euros and I agreed. The existing server has sufficient up to about 500 people online. So I had all the players ask "don't tell anyone about the game". And now I would not like anyone to show the current version, 5 people actively playing more than enough at the moment.
It became clear that the need to take or rent a new server.
Leasing I rejected, because I have positive experience of placing her
servers with a duration of 10 years.
Have a negative experience of closing a successful startup due to expensive hosting. I mean I had to pay 600$ a month for hosting, and the income at some point it became less than 600$ per month.
I therefore could not show it in the portfolio — and I believe it was caused terrible damage to my income as a whole.
It is because of these two reasons I decided to buy the server, instead of renting.
That is, if the online game will be financially insolvent — it is still online and will be available for the portfolio. And the cost of its contents will be quite feasible even with zero income from the game itself.
Besides, I need a server for multiple non-profit websites and teamspeak servers for a large Guild in a known online game.
Overview of all components in this server, still in boxes so we will be unpacking
the
I decided that the server needs to pull 50000 players online and 1000000 registered players.
While achieving these parameters, a startup grow into a business and will be able to buy new equipment. But in General, why is 50,000 instead of 60,000 — will not be considered, the article is not about that.
Further, the configuration selection — selection of parameters with the required parameters.
At the beginning of this story I'm pretty poorly versed in server hardware and what I really need.
I believe that the thinking and decision-making logic will be of great interest to all involved in the subject. Or decision makers.
All the parts in their boxes, now begins the unpacking and installation
the
To reduce financial risks it is necessary that the monthly expenses were minimal. Accordingly the server should be 1U in size.
The server part of the game is designed so that almost all can be run in megapolice. It is even possible to divide the task of rendering the game world across multiple servers.
This means that when "several productive cores" vs "many middle range of cores" — it is necessary to make a choice in favor of the second option.
Making some measurements, I decided that for 50,000 people online need 50Gb of RAM (again the article is not about why so much).
Suddenly it became clear that the game does a lot of writes to disk. So it should be ssd and fairly powerful.
Must be some kind of hdd for backups. I am one of those who are "already doing backups".
the
Processor manufacturer: Intel, AMD, MCST.
AMD — I tried to use the official AMD website, but unfortunately there it is impossible to understand:
The decision to abandon the purchase of AMD — a very inconvenient site, and legacy processors.
MCST is undoubtedly a very interesting, very interesting the fact of existence of Russian-made processors. That it is even possible to buy.
The inability to buy on behalf of a private person — too strained, but to solve the issue.
The inability to study the complete characteristics of the processor, there are no tests in the public domain. Even if synthetic. Also note the lack of support DDR4, but this is IMHO forgivable (for AMD is not excusable). The decision to abandon the purchase of MCST was after realizing the impossibility to use the command "apt-get upgrade".
Intel remains the only option. There is support for DDR4 memory in the last line of processors. There is a special section of the site where they dumped the sheet characteristics of the CPU — there I can find everything I'm interested in performance.

In the free market there are server options 1x, 2x, 4x, 8x.
Option to purchase a motherboard with multiple connectors and to install there a complete kit I decided not to consider. Why? To buy equipment it is a lot of time, nerves and money. This is in contrast to a home computer.
Options 4x-8x CPU was incredibly expensive and even in the most modest of equipment was prohibitive for me price. Uniprocessor and twoprocessor system was for different niches of the market. Here processor list to consider (those that begin with "E5-4" — uninteresting, they are for 4 CPU system).
Consider "E5-1" is the processor for uniprocessor systems.
Immediately struck by the high base frequency and high burst, but the number of nuclei of a very small number.
Here's an example "E5-1660 v4" 8 cores — 1113$, and the processor for duhadaway system, but with less frequency "E5-2620 v4" 8 cores — 422$.
The price is 3 times less in favor of a dual-processor system! Remember that the tasks much more useful and more weak cores, than few strong cores. On this it was decided to buy a dual-processor system.

Anyway remains quite a large selection of processors, what choices to make. I pay attention to consoles, type "L" or "W" or "A".
"L" is low power consumption. For me it is not interesting. If I would have had desks in a data center that would matter, but since I have 1U and any one data center does not want to put counter to my server — it is important.
"W" high energy consumption, A very good copy in the lineup. Pretty quickly, you notice that the remaining processors are divided into 2 groups. A small number of cores high frequency, a large number of cores+low frequency.
Discard the first group. Left a total of (higher cost 1500$ for a piece I decided not to consider):
E5-2603, E5-2609, E5-2620, E5-2630, E5-2640, E5-2650, E5-2660.
Immediately rejected too weak processors: E5-2603, E5-2609, because the money definitely will be enough for 2pcs E5-2620.
There is 5 options: E5-2620, E5-2630, E5-2640, E5-2650, E5-2660.
On closer examination it turned out that they can be divided into 2 groups according to the maximum allowable memory clock:
E5-2620, E5-2630, E5-2640 — 2133Mhz
E5-2650, E5-2660 — 2400Mhz
Consider 2 processors from this group:
Frequency E5-2630 vs E5-2650 no different. The only difference is +2 cores (and memory frequency a little more) and the price in 2 times more (+600$)! The second group is eliminated because of the price.
Now consider E5-2630 vs E5-2640
Differs only in the base frequency +10%, and the price is half as much. Clean version E5-2640. Incomprehensible overpayment to me.
It remains only E5-2620 vs E5-2630
The price difference is$ 250 and for them we get +10% frequency and +2 nuclei.
I'm ready for the price to the allowance.
Total the choice is made: Intel Xeon Processor E5-2630 v4

Remind: at the level of ideas — I decided that I need ~50Gb of memory. On the Internet I found that the collection of server memory is not a multiple of two is perfectly acceptable.
But all the same. Reasons that all memory should work the same way — so I don't have steamed what is the core of how difficult the task to submit — I've decided that the amount of memory must be a multiple of two.
Accordingly, it turns out that it is necessary to put 64Gb of memory. The server part of the game is written in such a way that on the server side fully calculated all the gameplay.
Thus cheating is impossible. However, if memory is not enough to completely fit in the memory of all players online will be a little crash, the game just won't start, and I need to make a hotfix. To be able to spill to disk intermediate results.
Once it became clear that if you have installed a lot of memory dies — falling speed communication processor with a memory.
So if I buy the 64Gb, and then buy the same again — it will be much worse than if I just buy a 128Gb.
The price difference turned out to be quite feasible, perhaps even enough for 256Gb, but the extra 1000$ was not the entire reserve eventually left in the ssd.
Installation of dies of memory, attentive gopher there may notice the 2400 memory. In fact, this memory's for photos, you need a memory came at the last moment.
the
I already knew that if you put too much of memory dies, it will be considerably slower than if you put less memory dies. So what is the best option is to put one plate on 128Gb?
It turns out the CPUs, there is such a thing as "memory channels". The best option in each memory channel on the same die memory. This rule is working and gaming/computers. Surprisingly, all bloggers do not convey this simple idea to the public.
Have my case is 2 CPU and each CPU with 4 memory channels. That is, for my case it is best to put 8 memory dies.
Total selection: 8 x 16Gb
Installation of dies of memory
the
The choice was not great. First choice is generally at the moment is 2133 and 2400. But the CPU pulls 2133. Is there any point in taking 2400?
It turns out not only makes no sense, but it is also bad (for my case). It turns out the memory access is performed in 17 cycles at 2400 memory, and 15 cycles at 2133 memory.
But my processor can't work with 2400 memory, it will be with her all the same work at a frequency of 2133. However, if the CPU was E5-2650 v4 or higher — then the opposite would be more profitable to put 2400 memory.
Another factor is the LRDIMM. This technology allows you to install more memory on the server, and when setting a maximum slats — this memory runs faster than if no LRDIMM.
LRDIMM is a server of conventional memory + some extra chips. Accordingly, the price +20% approximately.
For me respectively LRDIMM is not needed, because I don't set the memory in each slot.
Now the manufacturer. Among the server's memory it turns out the manufacturer doesn't matter. I'm not understand how this is possible — but fact. Synthetic tests are the same. Data memtest is about the same. For Kingston memory I found options: 2 options of saturation of the chips, but even in this case there is no functional difference.

The first time I made the desired server configuration — I wanted 1 on the 240gb ssd and one hdd at 2tb.
As you see, I have changed and understand what I need actually.
I had to know what ssd drives are very, very different. On servers it is better to use raid1.
That a new technology is NVMe, and she has a lot of options there. Raid controllers are very different for different tasks.
Let's order. Starting with "what do you want for the task?". Need 200Gb ssd drive that can withstand a lot of rewriting. And 2Tb hdd for reliable backups. "A lot of rewriting" — at a very rough calculation is 1-2Tb a day. Reliable backups — this means raid1 configuration. Hardware or software raid is the question of the size of the work, skill and responsibility in repairing the raid.
From the management perspective, the choice is this:
the
Respectively Tisk advised the cheapest of modern hardware raid controllers, which would allow so simply to repair possible damage.
This: ark.intel.com/ru/products/82030/Intel-Integrated-RAID-Module-RMS3CC040
I notice that it is a raid controller for the motherboard Intel. That is, if I choose the Intel platform is not something I would have to take something else and take as much as a pci slot.
I have no Idea what it is. Or something to do with encryption or something related to raid card,
preparation of the raid card to install

the
I was going to buy Western Digital due to the fact that I had a very positive experience with the use of hdd for home computers. But the Tisk said that they will only be able within weeks to make a replacement (warranty or not). And offered HGST said that it will be able to make a replacement during the day.
Began searching the Internet that write about the reliability of HGST — like normal reviews, and agreed with this choice of the producer disc.
Further, the volume. 2Tb need, good. And what we have is more expensive? +1Tb for 70$ more, well I'll never forgive myself that I saved on the volume, and if I then need more space. Well, further down the line similarly for a little bit increases the volume and slightly increases the price. Between 6Tb and 8Tb passed my border authority.
Total selection: 2pcs 6Tb HGST HDD.

First option: just to put 1pc ssd 200gb. Next, I learned that the larger the ssd the more the resource overwriting (ceteris paribus). And to faster this overwriting could do.
For example, I have 200gb of data and 240gb volume vs the volume of 1000gb. So other things being equal — resource rewrite large volume will be 4 times more.
So may the experts forgive me, but the decision is not obvious.
Then I realized, it is necessary to use MS raid1 and have 2 of these ssd. Yes, even though the backups are done every hour and not be scared to lose a single ssd. But there's Ms. the Axis settings only. The actual database. Will have to urgently spend a lot of time and effort to recover.
2tb Ssd can withstand a day of rewriting is very expensive. And still have reserve some for this indicator to have.
Then I learned about NVMe technology. It's simple: ssd drive connected as usual, but through the pci slot.
Stripe data more and faster — this is for my important tasks. Immediately the question arose — is it possible to combine them in a raid?
It turns out you can, but in selling such raid controllers no. There are prototypes with an unknown price.
In General at the time of purchase — it was not an option.
Another factor in the decision: let's say I bought 2 expensive ssd drive, combined them in a raid. But the resource overwrite them equally quickly consumed. And what do I get? What they will fail at the same time?
Then I found out that most ssd's fail not because of the grazing resource is overwritten, and because of the failure of the controller in the ssd. Yes, this raid will be relevant.
And here is a selection obtained between the pci-ssd (NVMe) and raid1-ssd. And with the above thought for me is definitely better pci-ssd. Well, just stupid there's another 2000$ on a backup ssd, but if I did, it is necessary to take 2U system and still over 400$ to buy a basket. Well, or buy 10 times worse than the ssd.
Well, Yes, I'm ready to trust a known brand (in this case Intel), in the hope that they have enough reliable device to the stated time and resource has worked without failure.

I am interested in ssd iops and write speed of an individual transaction, the amount, the resource being overwritten.
Reviewing the performance of thousands of ssd, I think in my case it is necessary to first look at the statement writer.
Almost all of the ssd can be divided into groups according to the number of times its volume a day, for 5 years. Group: 0.3, 1, 3, 10, 30, 100.
Almost always an exact match between the resource and overwrite the iops on record. Separately allocated ssd, read running with an incredible amount of iops but relatively weak on the recording. Such I for this server is not interesting.
Manufacturer: Intel, HGST, Huawei, HP, OCZ. Any of various ssd — an incredible number. Honestly — I have little idea how do people objectively choose the ssd need. Ssd all so much, they are so different, the price range is so huge.
From my point of view best of all grouped products Intel. They managed to break all the ssd into groups so that I could form an opinion of what device I need and what is not.
3 line of NVMe pci-ssd: P3500, P3600, P3700. At 400Gb:
P3700 — 75000 iops — 1000$, 10 rewrites a day
P3600 — 30000 iops — 650$, 3, being
P3500 — 23000 iops is 600$, 0.3, being
In fact it is obvious that P3500 soon disappears. For$ 50 a tenfold increase important I parameter.
Am I ready for 350$ to get ~a half times more iops and 3 times more resource overwrites? Kaneshna, Yes.
And here I was going to buy on P3700 400Gb, but for a couple of months prior to purchase there is a sale P4800X.
It costs almost 2 times more expensive P3700. A little less volume. write iops of 500,000. Resource rewriting 30.
That is a total for$ 800 I get 8 times more iops and 3 times more resource being overwritten.
Well, to be honest in terms of iops — it is simply beautiful and despite the fact that to get the extra 800$, it was not easy — I decided to buy this ssd.
The bonus is more rapid recording of each individual team.

I would also like to note that there is a type ssd SLC/MLC/TLC/QLC. The meaning differences clear: one physical cell is written several bits of data. Accordingly, the SLC only one. MLC or two. TLC — three. QLC — four. Left to right — from expensive to cheap. Due to the recording speed, reading of the resource rewrite.
SLC is the most reliable, the fastest, and... really expensive. For example, "Micron RealSSD P320h" hairy monster volume 350Gb just for 5000$. The claimed iops write 350000. Unlimited resource being overwritten.
MLC — are very different. Well this is the plant doing a bunch of memory chips, something good is put in a server option, something not very stick to the home version of the ssd.
TLC used to do openly, quickly breaking down, now like make good. And trying to make the perception that TLC is a good (if old sold out stupid buyers).
QLC — was trying to do, but apparently commodity option anyone failed to do.
Here Intel has recently released 3D-XPoint, is a new type of memory. As for me — a layer cake of ssd chips.
the
For servers, unlike home PCs to the choice of the motherboard fit very differently. For a home PC the actual size of the computer is not important, but for server we need to stick to 1U (It is 4.3 of an inch!).
Here now comes another approach to the selection of motherboards. Not sold motherboard and platform. That is, motherboard+case. The one who only sells the motherboard separately — immediately loses the competition.
The platform for this CPU are from different manufacturers. With little possible modifications to the sites, you can reference only a specific modification (mod will tell a little later):
Manufacturers HP and Dell — I will not be considered because of the monstrous overpayment is not clear why.
— Supermicro
— Asus
— Intel
— Separately, Intel
The choice of these four options is the cheapest option suitable for all requirements from each of the listed manufacturers. Price them about the same work. Option R1304WFTYS disappears as soon as you see power 1100W PSU (why this is important — more on that later).
About ASUS, I thought they recently came out on the market of server motherboards, it is not clear what I'm going to risk it.
About supermicro is they are actually only the server platforms have been doing for a very long time. But... the raid controller. Or I take Intel platform or do I need another controller and to occupy a PCI slot.
So I decided to choose Intel platform R1304WTTGSR. But note that it is 10% more expensive than similar platforms from supermicro.
Modification with 10 gbit ethernet. The price difference is$ 100, and if I need fat channel — I would not want to touch the server and install something. And I probably need a fat channel for the start of the game.

Of course first turned to hvosting.ua because I'm with them for more than 15 years has worked at it. Yes, and the volume of transactions exceeds the value of the discussed server. But placing servers in Kiev after the events of 2014 — is unacceptable for reasons of safety equipments.
hvosting.ua offered me a placement in the data center ttc teleport in Prague. But the discussion ended on the question "I want a piece of paper legally stating that I am the owner of the server". Well, I'm sorry, I'm not a College boy fully trust all.
However, if someone really need something to host in/Ukraine — I recommend hvosting.ua uptime was ~1200 days, then a planned migration servers in a nearby datacenter and uptime of 700 days. Next, I tried to do "apt-get upgrade" without restarting the server :) did Not work with debian itself is not able to be updated for 2000 days — some dependence are unable to correct itself. Hvosting helped to correct.
In General, for 15 years there was no power failure and the channel was falling for 15 minutes every 4 months, 2 times the channel went down for a few hours.
Especially delivered broken vk oauth authorization (at them there vk blocked).
the
There was a question on purchase in Russia, and accommodation is also in Russia. Why purchase and placement in Russia? And that I would be legally protected. Was a nice moment at the beginning of the search — choosing the best provider, no recommendation, no biases are all equal. Remember I started with a trivial search for "datacenter in Russia" (later I found out that in Russia it's called the data center). And "buy a server in Russia."
I will be right to tell in chronological order.

In the beginning there was a very constructive conversation with an interesting proposal. I studied the possibility of the raid1 option-NVMe was asked if they to the intel platform to put raid1-NVMe?
Suddenly had this question: rude refusal to answer (by the way I would have arranged to just answer "no," I just really was not aware of this case). Further did not want to communicate with them.
At first I saw P4800X to sell and so they decided to ask the details of the purchase.
The conversation ended on that without my personal presence in Moscow to make a deal impossible.

On the website they write that 12 years experience. And other cool figures. DNS whois shows that the domain was recently registered (3 months prior to consideration). I immediately occurs to them the question: "why such disparity?". Turns out before there was another company which left reviews online about "paid for a long time, no servers or money." You could be forgiven of specialists who created a new company after working with a bad Director. But unfortunately, what they wrote — not converged with the history of the DNS. Decided that the risks are unacceptable, although the price they offered interesting.

Citizens sell Used equipment. Then I have considered such options. Eventually decided not to consider, because DDR4 B/U no. sdd-hdd B/U is better not to take in any case. Well, it turns out they have nothing to offer me.

This is a regional equipment supplier. In principle a good option — they're right there. Then I thought maybe there is a decent data center in Krasnodar, but no — if there's a decent — full. Paradigm bent prices up and not have to answer my stupid questions.

As far as I remember — I was confused by the price. Honestly, even now I look at the price and don't understand why such a big price.

Their recommended data center tech.ru such as they cooperate with them. Listened to all my wishlist — picked what matched my wishlist at the time. At a great price. Next was to dig up DNS, whois, and reviews in the Internet.
DNS whois was identical to that described in the correspondence. The investigation has revealed many interesting details.
As it turned out the company was based, that has changed. Found how to change the website and asked otzyvov about him somewhere to write.
There were employees of the company. There were positive and negative reviews. All of this suggests that the company is old and somewhat actively engaged in constantly.
I checked the certificate from Intel — it was even outdated, but real. Checked some random certificate is also genuine. This was very pleased.
There is also a https. Also adds points in the direction of their company.
From the very beginning looked like a very good option.
12.12.2016
the
First contact is positive. But the price is just no words how big it is. Still here hanging by the brutal greed primer. Choose 400Gb NVMe 75k iops. This we corresponds to the Intel P3700. It turns out that all sell this piece of metal for 60,000±, and they are pushing it over 90,000.
Okay, maybe this new website with a bug somehow?.. But no, this is not a bug. Here we find the same on the main site with the old design:
stss.ru/products/servers/T-series/TX217.4-004LH.html?config=
Here in appropriate place select the same piece of metal also get +90000 value.
50% bonus gain is certainly very profitable, but sorry, we podem other way.

In General it was a very decent version of DNS and whois and reviews — looked good.
But the question "can they without my presence to deliver the server in the data center?" was not answered.
It would seriously have to choose between Tisk and Desten. I wish they had more patient support service — maybe I would server in the end bought them.
13.12.2016
the
They just sent me the configuration and price I was horrified and said nothing. Now I can see that the price is adequate, and why I was horrified — because they did not understand the meaning of the word "DWPD". Apparently I have with them was a phone conversation of some sort.

Citizens tried to sell me Dell equipment. Again, I see the overpayment for the brand at all clear what. The employee explains to me that the overpayment for prompt assistance. But I don't understand something — the server is in the rack data center to tier3. One of his legs will not be beat. In addition to factory defects — nothing can happen. Plus they said that can not like a Vise without my presence to set the server — it was not clear what more to say.

Now I have them on the website studenci see the server Configurator. Then they only had a website. And it was written that considering installment, I decided to ask on this topic. Said that such a small amount for installment is not interesting. They have servers DELL/HP — IMHO overpayment do not understand why.
Allow me to justify my nevasta these companies.
www.regard.ru/catalog/?query=2620+v4
I had someone explain the difference between "Intel Xeon E5-2620 v4 OEM and Dell Xeon E5-2620 v4 (338-BJEU)"? I now see only the difference in price in 2 times! The crystals of the Intel processors do. Ready to believe that they put the solder in the other, well, OK +50$ ready to understand. Explain to me silly that the DELL in this example takes +500$?
Apparently successfully they have worked the reminder and they called me a week before the final configuration negotiation with a Tisk. Tried to intercept me as a customer at the last moment. But... the price was higher than the Tisk.
the
As well as mail-order, ComputerUniverse, ogg and other platforms. An option that takes me to remote places, and then I somehow transfer to the Moscow — looks awful. Not only that, the entire profit from non-intermediaries young trees are consumed by the cost of delivery. So even time is incredibly much eat. And most importantly — the risks of damage appear (to hit about something for example).
Option with delivery to Moscow — need a room where I can collect the server plus a personal presence. Plus transtort between the point of delivery, point of Assembly, and data centers. Plus the risk of getting culled in the Assembly (art thou there well a secondary posting will not connect — will not be able to fix).
the
I noticed that the price ranges for each piece of iron in different stores. It is possible to run buy cheap in separate stores. But again the risks the curve of the Assembly. Personal presence, a place to build and transport. The question is — where's the profit from this event?
the
In the Outback of course there are shops and they are ready for a long time to deliver anything at a reasonable price. However, as it turned out, they somehow brains work differently. I explain to them that ssd is expensive I need here is such. And they — we don't have, here take another with similar characteristics. Of "similar" is considered only the volume.
But again — brought, it is necessary to collect (there is a risk that lost something), then shipping, personal presence, etc.
the
A very interesting option. People assemble computers to order. Straight talking: take a 4% Commission. All additional costs are at your expense. This position I liked, but no guarantees that it will not disappear after receiving the money — no. I don't understand. It hurt to say that there is an option with the contract, all properly executed juridichesky. This option will increase the cost by that much. So it would be a very interesting option. Here's the price, here are my 4% mark, that's additional expenses associated with the delivery, that spending on legal matters.
the
With these guys I never talked, but spent a lot of time.
I must admit — they have the most convenient Configurator from all sites. Comfortable is not, in terms of prettiness, but from the point of view of "how all of these characteristics to understand?". Did not communicate with them because they have nazeka at all 15% sravneniju with all the others. They have a lot of certificates of all sorts, for myself concluded that the municipalities of the environs of Moscow region or Moscow is the best equipment supplier. And for me there in the first place because of the margins.
Their Configurator is so great that the zasluzhivat special attention. Consider this example. Maybe they should sell it as a service to other companies? Type unload your prices and things, and the users have to assemble themselves what they need. Well... if the Tisk was such a Configurator — that would be super great.
At first glance, is a bad design. But we're not a beauty salon.
Yet I note that despite Kazumasa the simplicity in it is hidden a huge number of small and useful functionality. Platform. It is through this website until I finally realized how to select motherboard for servers (in the form of platforms and their modifications). Also it just shows all the modifications. It is seen that for ssd and hdd. It is seen that the 10GbE and 1GbE. Then just visually it becomes clear that if I want to put a hdd 2 modifications I did are not suitable. And the difference in price on the topic of 10GbE and 1GbE — 1GbE is+10% = 10GbE. And all the more do not need to think and compare, ask stupid questions our suppliers. Looking at it — once everything is clear.
Next, the unit processor — can be clearly seen which processors you can stick in the platform. Processor with a lot of the characteristics on stage, "I don't understand but want to understand" — to throw out to bars all the different characteristics — very helpful and very reasonable. This section helped me a lot to understand what features of the processor are important for decision-making and which are not.
Further, the block memory, and suddenly he, too, helped greatly to understand what characteristics are necessary to look for decision-making. Here you can see very clearly that it is necessary to take into account the memory frequency and RDIMM/LRDIMM. I wrote about this before.

Why do I need a server
In August 2015 successfully formed the circumstances, so I started to do online game.
I had quite a large selection of unfinished what to do. For a number of reasons chose online the game.
Started to do it and for half a year of hard work made good progress, but then the savings ran out. Nevertheless, I went very far in this matter and then continued to Refine the online game in their spare time. The game requires a lot of server resources for the rating calculation.
I had 10 years a personal server in Kiev data center hvosting.ua. He got me by chance: "I Want a server like that, that's 750евро and pay only for rack space?", well, I then once again had an extra 750 euros and I agreed. The existing server has sufficient up to about 500 people online. So I had all the players ask "don't tell anyone about the game". And now I would not like anyone to show the current version, 5 people actively playing more than enough at the moment.
It became clear that the need to take or rent a new server.
Leasing I rejected, because I have positive experience of placing her
servers with a duration of 10 years.
Have a negative experience of closing a successful startup due to expensive hosting. I mean I had to pay 600$ a month for hosting, and the income at some point it became less than 600$ per month.
I therefore could not show it in the portfolio — and I believe it was caused terrible damage to my income as a whole.
It is because of these two reasons I decided to buy the server, instead of renting.
That is, if the online game will be financially insolvent — it is still online and will be available for the portfolio. And the cost of its contents will be quite feasible even with zero income from the game itself.
Besides, I need a server for multiple non-profit websites and teamspeak servers for a large Guild in a known online game.
Overview of all components in this server, still in boxes so we will be unpacking
the
select a configuration
I decided that the server needs to pull 50000 players online and 1000000 registered players.
While achieving these parameters, a startup grow into a business and will be able to buy new equipment. But in General, why is 50,000 instead of 60,000 — will not be considered, the article is not about that.
Further, the configuration selection — selection of parameters with the required parameters.
At the beginning of this story I'm pretty poorly versed in server hardware and what I really need.
I believe that the thinking and decision-making logic will be of great interest to all involved in the subject. Or decision makers.
All the parts in their boxes, now begins the unpacking and installation
the
Overall performance
To reduce financial risks it is necessary that the monthly expenses were minimal. Accordingly the server should be 1U in size.
The server part of the game is designed so that almost all can be run in megapolice. It is even possible to divide the task of rendering the game world across multiple servers.
This means that when "several productive cores" vs "many middle range of cores" — it is necessary to make a choice in favor of the second option.
Making some measurements, I decided that for 50,000 people online need 50Gb of RAM (again the article is not about why so much).
Suddenly it became clear that the game does a lot of writes to disk. So it should be ssd and fairly powerful.
Must be some kind of hdd for backups. I am one of those who are "already doing backups".
the
choose processor
Processor manufacturer: Intel, AMD, MCST.
AMD — I tried to use the official AMD website, but unfortunately there it is impossible to understand:
-
the
- Which processors they generally are. Able to understand studying is not the official site (all other sites). the
- Which processors are the most popular. At the time of the study, the latest server processors had no support DDR4. Did not continue to study.
The decision to abandon the purchase of AMD — a very inconvenient site, and legacy processors.
MCST is undoubtedly a very interesting, very interesting the fact of existence of Russian-made processors. That it is even possible to buy.
The inability to buy on behalf of a private person — too strained, but to solve the issue.
The inability to study the complete characteristics of the processor, there are no tests in the public domain. Even if synthetic. Also note the lack of support DDR4, but this is IMHO forgivable (for AMD is not excusable). The decision to abandon the purchase of MCST was after realizing the impossibility to use the command "apt-get upgrade".
Intel remains the only option. There is support for DDR4 memory in the last line of processors. There is a special section of the site where they dumped the sheet characteristics of the CPU — there I can find everything I'm interested in performance.

Number of processors
In the free market there are server options 1x, 2x, 4x, 8x.
Option to purchase a motherboard with multiple connectors and to install there a complete kit I decided not to consider. Why? To buy equipment it is a lot of time, nerves and money. This is in contrast to a home computer.
Options 4x-8x CPU was incredibly expensive and even in the most modest of equipment was prohibitive for me price. Uniprocessor and twoprocessor system was for different niches of the market. Here processor list to consider (those that begin with "E5-4" — uninteresting, they are for 4 CPU system).
Consider "E5-1" is the processor for uniprocessor systems.
Immediately struck by the high base frequency and high burst, but the number of nuclei of a very small number.
Here's an example "E5-1660 v4" 8 cores — 1113$, and the processor for duhadaway system, but with less frequency "E5-2620 v4" 8 cores — 422$.
The price is 3 times less in favor of a dual-processor system! Remember that the tasks much more useful and more weak cores, than few strong cores. On this it was decided to buy a dual-processor system.
Both CPU E5-2630 v4 installed in their slots

Anyway remains quite a large selection of processors, what choices to make. I pay attention to consoles, type "L" or "W" or "A".
"L" is low power consumption. For me it is not interesting. If I would have had desks in a data center that would matter, but since I have 1U and any one data center does not want to put counter to my server — it is important.
"W" high energy consumption, A very good copy in the lineup. Pretty quickly, you notice that the remaining processors are divided into 2 groups. A small number of cores high frequency, a large number of cores+low frequency.
Discard the first group. Left a total of (higher cost 1500$ for a piece I decided not to consider):
E5-2603, E5-2609, E5-2620, E5-2630, E5-2640, E5-2650, E5-2660.
Immediately rejected too weak processors: E5-2603, E5-2609, because the money definitely will be enough for 2pcs E5-2620.
There is 5 options: E5-2620, E5-2630, E5-2640, E5-2650, E5-2660.
On closer examination it turned out that they can be divided into 2 groups according to the maximum allowable memory clock:
E5-2620, E5-2630, E5-2640 — 2133Mhz
E5-2650, E5-2660 — 2400Mhz
Consider 2 processors from this group:
Frequency E5-2630 vs E5-2650 no different. The only difference is +2 cores (and memory frequency a little more) and the price in 2 times more (+600$)! The second group is eliminated because of the price.
Now consider E5-2630 vs E5-2640
Differs only in the base frequency +10%, and the price is half as much. Clean version E5-2640. Incomprehensible overpayment to me.
It remains only E5-2620 vs E5-2630
The price difference is$ 250 and for them we get +10% frequency and +2 nuclei.
I'm ready for the price to the allowance.
Total the choice is made: Intel Xeon Processor E5-2630 v4

choose memory
Remind: at the level of ideas — I decided that I need ~50Gb of memory. On the Internet I found that the collection of server memory is not a multiple of two is perfectly acceptable.
But all the same. Reasons that all memory should work the same way — so I don't have steamed what is the core of how difficult the task to submit — I've decided that the amount of memory must be a multiple of two.
Accordingly, it turns out that it is necessary to put 64Gb of memory. The server part of the game is written in such a way that on the server side fully calculated all the gameplay.
Thus cheating is impossible. However, if memory is not enough to completely fit in the memory of all players online will be a little crash, the game just won't start, and I need to make a hotfix. To be able to spill to disk intermediate results.
Once it became clear that if you have installed a lot of memory dies — falling speed communication processor with a memory.
So if I buy the 64Gb, and then buy the same again — it will be much worse than if I just buy a 128Gb.
The price difference turned out to be quite feasible, perhaps even enough for 256Gb, but the extra 1000$ was not the entire reserve eventually left in the ssd.
Installation of dies of memory, attentive gopher there may notice the 2400 memory. In fact, this memory's for photos, you need a memory came at the last moment.
the
select the number of dies of memory
I already knew that if you put too much of memory dies, it will be considerably slower than if you put less memory dies. So what is the best option is to put one plate on 128Gb?
It turns out the CPUs, there is such a thing as "memory channels". The best option in each memory channel on the same die memory. This rule is working and gaming/computers. Surprisingly, all bloggers do not convey this simple idea to the public.
Have my case is 2 CPU and each CPU with 4 memory channels. That is, for my case it is best to put 8 memory dies.
Total selection: 8 x 16Gb
Installation of dies of memory
the
Selection of memory model
The choice was not great. First choice is generally at the moment is 2133 and 2400. But the CPU pulls 2133. Is there any point in taking 2400?
It turns out not only makes no sense, but it is also bad (for my case). It turns out the memory access is performed in 17 cycles at 2400 memory, and 15 cycles at 2133 memory.
But my processor can't work with 2400 memory, it will be with her all the same work at a frequency of 2133. However, if the CPU was E5-2650 v4 or higher — then the opposite would be more profitable to put 2400 memory.
Another factor is the LRDIMM. This technology allows you to install more memory on the server, and when setting a maximum slats — this memory runs faster than if no LRDIMM.
LRDIMM is a server of conventional memory + some extra chips. Accordingly, the price +20% approximately.
For me respectively LRDIMM is not needed, because I don't set the memory in each slot.
Now the manufacturer. Among the server's memory it turns out the manufacturer doesn't matter. I'm not understand how this is possible — but fact. Synthetic tests are the same. Data memtest is about the same. For Kingston memory I found options: 2 options of saturation of the chips, but even in this case there is no functional difference.

Choose disk subsystem
The first time I made the desired server configuration — I wanted 1 on the 240gb ssd and one hdd at 2tb.
As you see, I have changed and understand what I need actually.
I had to know what ssd drives are very, very different. On servers it is better to use raid1.
That a new technology is NVMe, and she has a lot of options there. Raid controllers are very different for different tasks.
Let's order. Starting with "what do you want for the task?". Need 200Gb ssd drive that can withstand a lot of rewriting. And 2Tb hdd for reliable backups. "A lot of rewriting" — at a very rough calculation is 1-2Tb a day. Reliable backups — this means raid1 configuration. Hardware or software raid is the question of the size of the work, skill and responsibility in repairing the raid.
From the management perspective, the choice is this:
the
-
the
- Software raid needed skills to repair the raid, the slightest mistake and data lost. But it is cheaper. the
- Hardware raid — just replace the failed drive and all. But it is expensive.
Respectively Tisk advised the cheapest of modern hardware raid controllers, which would allow so simply to repair possible damage.
This: ark.intel.com/ru/products/82030/Intel-Integrated-RAID-Module-RMS3CC040
I notice that it is a raid controller for the motherboard Intel. That is, if I choose the Intel platform is not something I would have to take something else and take as much as a pci slot.
I have no Idea what it is. Or something to do with encryption or something related to raid card,
preparation of the raid card to install

HDD Model
I was going to buy Western Digital due to the fact that I had a very positive experience with the use of hdd for home computers. But the Tisk said that they will only be able within weeks to make a replacement (warranty or not). And offered HGST said that it will be able to make a replacement during the day.
Began searching the Internet that write about the reliability of HGST — like normal reviews, and agreed with this choice of the producer disc.
Further, the volume. 2Tb need, good. And what we have is more expensive? +1Tb for 70$ more, well I'll never forgive myself that I saved on the volume, and if I then need more space. Well, further down the line similarly for a little bit increases the volume and slightly increases the price. Between 6Tb and 8Tb passed my border authority.
Total selection: 2pcs 6Tb HGST HDD.

select the type of SSD
First option: just to put 1pc ssd 200gb. Next, I learned that the larger the ssd the more the resource overwriting (ceteris paribus). And to faster this overwriting could do.
For example, I have 200gb of data and 240gb volume vs the volume of 1000gb. So other things being equal — resource rewrite large volume will be 4 times more.
So may the experts forgive me, but the decision is not obvious.
Then I realized, it is necessary to use MS raid1 and have 2 of these ssd. Yes, even though the backups are done every hour and not be scared to lose a single ssd. But there's Ms. the Axis settings only. The actual database. Will have to urgently spend a lot of time and effort to recover.
2tb Ssd can withstand a day of rewriting is very expensive. And still have reserve some for this indicator to have.
Then I learned about NVMe technology. It's simple: ssd drive connected as usual, but through the pci slot.
Stripe data more and faster — this is for my important tasks. Immediately the question arose — is it possible to combine them in a raid?
It turns out you can, but in selling such raid controllers no. There are prototypes with an unknown price.
In General at the time of purchase — it was not an option.
Another factor in the decision: let's say I bought 2 expensive ssd drive, combined them in a raid. But the resource overwrite them equally quickly consumed. And what do I get? What they will fail at the same time?
Then I found out that most ssd's fail not because of the grazing resource is overwritten, and because of the failure of the controller in the ssd. Yes, this raid will be relevant.
And here is a selection obtained between the pci-ssd (NVMe) and raid1-ssd. And with the above thought for me is definitely better pci-ssd. Well, just stupid there's another 2000$ on a backup ssd, but if I did, it is necessary to take 2U system and still over 400$ to buy a basket. Well, or buy 10 times worse than the ssd.
Well, Yes, I'm ready to trust a known brand (in this case Intel), in the hope that they have enough reliable device to the stated time and resource has worked without failure.

I am interested in ssd iops and write speed of an individual transaction, the amount, the resource being overwritten.
Reviewing the performance of thousands of ssd, I think in my case it is necessary to first look at the statement writer.
Almost all of the ssd can be divided into groups according to the number of times its volume a day, for 5 years. Group: 0.3, 1, 3, 10, 30, 100.
Almost always an exact match between the resource and overwrite the iops on record. Separately allocated ssd, read running with an incredible amount of iops but relatively weak on the recording. Such I for this server is not interesting.
Manufacturer: Intel, HGST, Huawei, HP, OCZ. Any of various ssd — an incredible number. Honestly — I have little idea how do people objectively choose the ssd need. Ssd all so much, they are so different, the price range is so huge.
From my point of view best of all grouped products Intel. They managed to break all the ssd into groups so that I could form an opinion of what device I need and what is not.
3 line of NVMe pci-ssd: P3500, P3600, P3700. At 400Gb:
P3700 — 75000 iops — 1000$, 10 rewrites a day
P3600 — 30000 iops — 650$, 3, being
P3500 — 23000 iops is 600$, 0.3, being
In fact it is obvious that P3500 soon disappears. For$ 50 a tenfold increase important I parameter.
Am I ready for 350$ to get ~a half times more iops and 3 times more resource overwrites? Kaneshna, Yes.
And here I was going to buy on P3700 400Gb, but for a couple of months prior to purchase there is a sale P4800X.
It costs almost 2 times more expensive P3700. A little less volume. write iops of 500,000. Resource rewriting 30.
That is a total for$ 800 I get 8 times more iops and 3 times more resource being overwritten.
Well, to be honest in terms of iops — it is simply beautiful and despite the fact that to get the extra 800$, it was not easy — I decided to buy this ssd.
The bonus is more rapid recording of each individual team.

about ssd
I would also like to note that there is a type ssd SLC/MLC/TLC/QLC. The meaning differences clear: one physical cell is written several bits of data. Accordingly, the SLC only one. MLC or two. TLC — three. QLC — four. Left to right — from expensive to cheap. Due to the recording speed, reading of the resource rewrite.
SLC is the most reliable, the fastest, and... really expensive. For example, "Micron RealSSD P320h" hairy monster volume 350Gb just for 5000$. The claimed iops write 350000. Unlimited resource being overwritten.
MLC — are very different. Well this is the plant doing a bunch of memory chips, something good is put in a server option, something not very stick to the home version of the ssd.
TLC used to do openly, quickly breaking down, now like make good. And trying to make the perception that TLC is a good (if old sold out stupid buyers).
QLC — was trying to do, but apparently commodity option anyone failed to do.
Here Intel has recently released 3D-XPoint, is a new type of memory. As for me — a layer cake of ssd chips.
the
the manufacturer
For servers, unlike home PCs to the choice of the motherboard fit very differently. For a home PC the actual size of the computer is not important, but for server we need to stick to 1U (It is 4.3 of an inch!).
Here now comes another approach to the selection of motherboards. Not sold motherboard and platform. That is, motherboard+case. The one who only sells the motherboard separately — immediately loses the competition.
The platform for this CPU are from different manufacturers. With little possible modifications to the sites, you can reference only a specific modification (mod will tell a little later):
Manufacturers HP and Dell — I will not be considered because of the monstrous overpayment is not clear why.
— Supermicro
— Asus
— Intel
— Separately, Intel
The choice of these four options is the cheapest option suitable for all requirements from each of the listed manufacturers. Price them about the same work. Option R1304WFTYS disappears as soon as you see power 1100W PSU (why this is important — more on that later).
About ASUS, I thought they recently came out on the market of server motherboards, it is not clear what I'm going to risk it.
About supermicro is they are actually only the server platforms have been doing for a very long time. But... the raid controller. Or I take Intel platform or do I need another controller and to occupy a PCI slot.
So I decided to choose Intel platform R1304WTTGSR. But note that it is 10% more expensive than similar platforms from supermicro.
Modification with 10 gbit ethernet. The price difference is$ 100, and if I need fat channel — I would not want to touch the server and install something. And I probably need a fat channel for the start of the game.

where to buy
Of course first turned to hvosting.ua because I'm with them for more than 15 years has worked at it. Yes, and the volume of transactions exceeds the value of the discussed server. But placing servers in Kiev after the events of 2014 — is unacceptable for reasons of safety equipments.
hvosting.ua offered me a placement in the data center ttc teleport in Prague. But the discussion ended on the question "I want a piece of paper legally stating that I am the owner of the server". Well, I'm sorry, I'm not a College boy fully trust all.
However, if someone really need something to host in/Ukraine — I recommend hvosting.ua uptime was ~1200 days, then a planned migration servers in a nearby datacenter and uptime of 700 days. Next, I tried to do "apt-get upgrade" without restarting the server :) did Not work with debian itself is not able to be updated for 2000 days — some dependence are unable to correct itself. Hvosting helped to correct.
In General, for 15 years there was no power failure and the channel was falling for 15 minutes every 4 months, 2 times the channel went down for a few hours.
Especially delivered broken vk oauth authorization (at them there vk blocked).

market Overview
There was a question on purchase in Russia, and accommodation is also in Russia. Why purchase and placement in Russia? And that I would be legally protected. Was a nice moment at the beginning of the search — choosing the best provider, no recommendation, no biases are all equal. Remember I started with a trivial search for "datacenter in Russia" (later I found out that in Russia it's called the data center). And "buy a server in Russia."
I will be right to tell in chronological order.

In the beginning there was a very constructive conversation with an interesting proposal. I studied the possibility of the raid1 option-NVMe was asked if they to the intel platform to put raid1-NVMe?
Suddenly had this question: rude refusal to answer (by the way I would have arranged to just answer "no," I just really was not aware of this case). Further did not want to communicate with them.
At first I saw P4800X to sell and so they decided to ask the details of the purchase.
The conversation ended on that without my personal presence in Moscow to make a deal impossible.

On the website they write that 12 years experience. And other cool figures. DNS whois shows that the domain was recently registered (3 months prior to consideration). I immediately occurs to them the question: "why such disparity?". Turns out before there was another company which left reviews online about "paid for a long time, no servers or money." You could be forgiven of specialists who created a new company after working with a bad Director. But unfortunately, what they wrote — not converged with the history of the DNS. Decided that the risks are unacceptable, although the price they offered interesting.

As it turned out the company was based, that has changed. Found how to change the website and asked otzyvov about him somewhere to write.
There were employees of the company. There were positive and negative reviews. All of this suggests that the company is old and somewhat actively engaged in constantly.

The crystals of the Intel processors do. Ready to believe that they put the solder in the other, well, OK +50$ ready to understand. Explain to me silly that the DELL in this example takes +500$?
Apparently successfully they have worked the reminder and they called me a week before the final configuration negotiation with a Tisk. Tried to intercept me as a customer at the last moment. But... the price was higher than the Tisk.
the
Ebay
As well as mail-order, ComputerUniverse, ogg and other platforms. An option that takes me to remote places, and then I somehow transfer to the Moscow — looks awful. Not only that, the entire profit from non-intermediaries young trees are consumed by the cost of delivery. So even time is incredibly much eat. And most importantly — the risks of damage appear (to hit about something for example).
Option with delivery to Moscow — need a room where I can collect the server plus a personal presence. Plus transtort between the point of delivery, point of Assembly, and data centers. Plus the risk of getting culled in the Assembly (art thou there well a secondary posting will not connect — will not be able to fix).
the
Samoa to run in Moscow
I noticed that the price ranges for each piece of iron in different stores. It is possible to run buy cheap in separate stores. But again the risks the curve of the Assembly. Personal presence, a place to build and transport. The question is — where's the profit from this event?
the
Local shop
In the Outback of course there are shops and they are ready for a long time to deliver anything at a reasonable price. However, as it turned out, they somehow brains work differently. I explain to them that ssd is expensive I need here is such. And they — we don't have, here take another with similar characteristics. Of "similar" is considered only the volume.
But again — brought, it is necessary to collect (there is a risk that lost something), then shipping, personal presence, etc.

A very interesting option. People assemble computers to order. Straight talking: take a 4% Commission. All additional costs are at your expense. This position I liked, but no guarantees that it will not disappear after receiving the money — no. I don't understand. It hurt to say that there is an option with the contract, all properly executed juridichesky. This option will increase the cost by that much. So it would be a very interesting option. Here's the price, here are my 4% mark, that's additional expenses associated with the delivery, that spending on legal matters.

With these guys I never talked, but spent a lot of time.
I must admit — they have the most convenient Configurator from all sites. Comfortable is not, in terms of prettiness, but from the point of view of "how all of these characteristics to understand?". Did not communicate with them because they have nazeka at all 15% sravneniju with all the others. They have a lot of certificates of all sorts, for myself concluded that the municipalities of the environs of Moscow region or Moscow is the best equipment supplier. And for me there in the first place because of the margins.
Their Configurator is so great that the zasluzhivat special attention. Consider this example. Maybe they should sell it as a service to other companies? Type unload your prices and things, and the users have to assemble themselves what they need. Well... if the Tisk was such a Configurator — that would be super great.
At first glance, is a bad design. But we're not a beauty salon.
Yet I note that despite Kazumasa the simplicity in it is hidden a huge number of small and useful functionality. Platform. It is through this website until I finally realized how to select motherboard for servers (in the form of platforms and their modifications). Also it just shows all the modifications. It is seen that for ssd and hdd. It is seen that the 10GbE and 1GbE. Then just visually it becomes clear that if I want to put a hdd 2 modifications I did are not suitable. And the difference in price on the topic of 10GbE and 1GbE — 1GbE is+10% = 10GbE. And all the more do not need to think and compare, ask stupid questions our suppliers. Looking at it — once everything is clear.
Next, the unit processor — can be clearly seen which processors you can stick in the platform. Processor with a lot of the characteristics on stage, "I don't understand but want to understand" — to throw out to bars all the different characteristics — very helpful and very reasonable. This section helped me a lot to understand what features of the processor are important for decision-making and which are not.
Further, the block memory, and suddenly he, too, helped greatly to understand what characteristics are necessary to look for decision-making. Here you can see very clearly that it is necessary to take into account the memory frequency and RDIMM/LRDIMM. I wrote about this before.
Then I realized how to assemble raid1-nvme. View here. There you can choose baskets Article based on information from habrahabr.ru
