[WTB] 19" RackMount GPU Frame

[miaviator]

19" RackMount GPU Frame

Must Meet the following:
Mounting bracket (front and back) to fit in a standard 19" 4 post rack at 24-30" depth
4U max height
mounting plates for 2 sets of 3-4 120mm x 38mm fans
mounting equipment for 6 GPU's (With no PCIE metal brackets attached!)
*Adjustable positioning of cards/card spacing
The power supply will be a Corsair AX1200 or similar
GPU's must be on the rear of the frame facing the rear of the rack when mounted.
must have top/bottom and both sides covered with an easy to remove lid.
must have room to plug in power to the top of the GPU's and extenders to the bottom of the GPU's

It has to be made of metal.  No plastic/cardboard/etc. etc.  I can burn down the DC on my own.

I've found nothing that comes close to meeting these specs. Though I've been known to be late to the party.


Something Like THIS: 

[crazyates]

I would be interested in these as well! Like really interested. We'd probably buy a ton of them.

Two thing I'd change:

Limiting the GPUs from 6 to 5? Or at least making it an option? A standard GPU is ~1.5" wide? That RSV-L4500 is only 16.8" wide on the inside? That's barely 1.3" between the GPUs. At least with 5 GPUs, you can get up to a 1.8" spacing between them. We've been putting 5 GPUs on a 19" rack, and it's really narrow. I get jealous of these open aluminum rigs with like 2-3" between each of their GPUs.

Also, the option to build in a second PSU. I know space is a big concern in cramming all of this hardware in a chassis, but if it is even remotely possible, that'd be huge. Powering 6x 280x would require something bigger than a 1200W. May not be possible, but the hundreds of savings per rig make it worth looking into.

That said, if anyone wants to design/build one, I've been doodling for a few weeks now on different layouts and ways of mounting everything, and I'd be happy to share with you!

[Spotswood]

Have you verified that you can mount a GPU on risers in a 4u case?

Yes.

So far it would appear that I'll be having these manufactured

Also very interested. Probably going to order that Rosewell case just to fiddle with it. Just adding 2-3 aluminum support beams with tapped holes to fix the GPUs on risers should do the trick.
I also think that 5 is the max number of GPUs that will fit in there, but let's see what can be done.

Do you also think about moving your rigs into a data center before it gets hot this summer?

Nearest I have found is the Cyclone cases, but they arent cheap!

My problem is the unused data center space.  I can't stick open rigs into a real datacenter so I've been looking for rackmount solutions.

You're looking at probably $2k+ for reach 4 or 5U system.

[miaviator]

Those still won't come close to what I need.

Thanks. Yeah, those boards with 8 PCIe slot are way too pricey. Plus, 8 high-end videos card in 4U is overkill in terms of energy density, if you plan to fill a complete rack - which would be maxed out between 8-14kW, accordings to my recent inquiries.

So 4-5 cards per 4U seems about right. I just ordered one case to fiddle with it, and see what can be done.

Then this looks like a project we can work on... We make custom industrial frames all the time so this is not any different...

Do you have any ideas on the design?

I'm going to look at these once when I unbox and load them up.  After that I won't see them again for 6-12 months.   You can make these out of the ugliest crap you can find for all I care.  Or paint them hot pink.  Or use left over car parts.  I only care about function. 

Also if you can make the frame and internal mounting setup I could have the top/bottom/sides made here in the US to save on shipping costs.  And if you can make it some assembly required you could flat pack it to save more on shipping.

Something like that, but your proposal is definitely higher than 4U.
What is the height you are planning?

[miaviator]

Very close.  But that beast looks to be 6-8 Rack units which nets 50-75% rigs per rack compared to my solution.  Also you have PCI brackets still on the cards for mounting and power below the cards which is a terrible idea for heat.

*And why would you put all that hardware in a rig and use a 3.5" non SSD hard drive?

[Tom22]

This is 6u I have yet to be able to get 2 PS, mb, and 6 gpu into less then 5 and even then there is very little room for the top connectors on the gpu's

PM me for a phone number to chat if your interested.

below is a link to my shop

I can do it in 4u if you don't mind it almost 30" deep.

The Power supplies are in the back under the cards to have the power connectors to the rear.
No heat is added as most newer PS'S ext to the back.
The hard drive is an example any drive bracket can be made.
I plan on doing these as kit (build your own) systems with options like rear card supports, extra fan banks, MB under GPU for standard risers and PS to the front.

The issue I see is that you are drawing heat from the GPU's and pulling it into the PSU, It's likely better than my solution which spits PSU heat into the GPU's but it's still going to heat up the PSU a lot.  Especially if you are like me and load up PSU's to 90-110% 24x7

Can you put 140MM fans in that center bank, make the gpu's center mounted vertically so there is room above and below, leave the space between the gpus open on the back of the case so air can flow by the cards (needed for non reference model cards)

[miaviator]

It also looks like you could put a large fan between the PSU's on the front though it would have to be a hell of a high pressure high cfm fan to supply the three 120-140's in the center so open air may be better.

Those PSU's should exhale onto the GPUs or have a vent to push the air above or below the gpu's

All of those thing can be done, or at least most of them. If you are using 120mm server fans they flow about 100cfm each! The center fans can pull air from the front or thru vent slots on the sides.
With everything closed up all the air will pass thru the GPU's and slots between the GPU's.
The front and rear can be turned into swiss cheese to get air in as well.

Do you really need more then 300cfm? I'm running 6 290x's with a 1600w + 850w power supplies and have no problems with temps.

A 5 min phone call can solve all the issues.

I like it! Dumb question, tho: which end are you referring to when you say "front" and "rear"? I kind of assumed that the PSUs and MB connectors would be at the front, and the PSUs would blow the hot air out the back, but your wording makes me not sure.

So for the 4U version, you would have everything the same as pictured, except:

-GPUs would be centered vertically, to allow for riser depth on the bottom, and PSU power plugs on the top.
-GPU backplate would be swiss cheese mesh, to allow for airflow.
-3 center fans would be upgraded to 140mm sizes. Will these be too tall for proper cable management, with risers below, and PCIe power above?
-Most of the metal case on the front (between PSUs and MB) and sides (before the fans) would be vented swiss cheese.

That actually sounds perfect. How much are you looking to charge?

Here is a updated version. Moved the PS to the bottom for easier MB access.

1.   GPU'S are centered. Reversed PS and MB (you can flip the front plate to reverse it again).
2.   Back plate is swiss cheesed I still have to add vents to the front and sides.
3.   Right now the fans are 120mm and I added slots below the fans for wire control.
4.   Swiss cheese incomming!!!!
5.   I still have to add GPU rear support, Power/Reset switches

Once all the updates are done I should have a more exact price, But I'm looking to make it modular I.E. Rear Plate for 4 or 5 cards, 1/2/3 PS's, and just about anything else you can think of.

Please post any more ideas. I'll try to get in what I can.

[miaviator]

I'd still like to see the specs in the op

Specifically card mounts built in to run the cards with no PCI brackets and adjustable mounts to evenly space 3-6 GPUs.

AHHHHH....So you want a back that is completely open and you can slide the cards from side to side.
And a rear support that does the same. amiright?

[Gazza1]

I am looking forward to seeing pics of this

[ADT]

I think you could fit 8 GPU in a 4u case with a bit of creative thinking ( 2 systems of 4 cards )

my Skype is zack.clark4 if you want to talk about it

Edit also it would be worth considering going 8u and running 4 systems of 4 cards each as you could use the space a lot better

Correct.  I want to run 2-4 High High End cards or 4-6 mid range cards.

If 10 of these go into a rack It'll hit 10Kw+ per rack pretty quick so some space for adjustment is needed.  Also there is a need for different spacing for future cards and systems.

[Tom22]

OK, Here's the latest update with I think is what the OP wanted.

The cards can be moved from side to side with any amount of cards kind of like an open rack.
1 PS (although a second can be added).
4 80mm front fans, 3 120mm mid fans and 3 120mm rear fan in removable tray.

Need to get more info from the OP on the rear card support.

Sweet science, I've been dreaming of a case like this. Please tell me you made them and are selling them. If so, I would like to place an order.

[miaviator]

I gave up for now 

[Sophokles]

I gave up for now 

Why ?

[miaviator]

I gave up for now 

Why ?

It's been several years.  I'm in no rush to expect someone to actually pull through and make this case.  Besides I have plenty of room for 3 card PC cased rigs.

As long as you use positive pressure for reference and negative pressure for non reference and cool the backs of the cards it's fine.

[EricKennedy]

I'm in the process of producing 4U cases with the help of a local factory.
6 GPU, exhaust fans, 2 PSU, Mobo small format (like the H81 PRO BTC)

Here are the prototype specs :



Initial version with 5 GPUs and 2 PSU on the front









I should have the second prototype (6 GPU, rear PSU + option dual PSU) soon.
Please tell me if you could be interested.

Only problem is I'm in Europe, so shipping could be a problem.

Eric

[miaviator]

That would work for a lot of open air people.  There is nothing between the gpus to create any kind of pressure.  If I use non-reference in that case I would be sucking air out from the intake fans on the cards, If I use reference I would be blowing from a strong fan to a week fan and sucking untouched air above and around the GPU's

I think I'll start selling my own for $150 + shipping in the US

I might be able to get it down to $100 depending on GPU count and mounts.

[sebastiebass]

Here in the Netherlands that gorgeous case EricKennedy posted, would sadly be rejected for placement in a rack (hosted in a datacenter)

Rules apply besides hight and width.

But in the end I guess it all comes down to how much space you are willing to buy and the percentage of occupation at the given datacenter.

Furthermore, wouldn't the amount of air pressure needed to keep things cool enough, (is there any way to calculate this given the OP's demands?) destroy the fans on the cards?

Looks nice, but too pricey. You could get two of these for the same cost:

http://miningrigsnet.gostorego.com/server-cases.html

and put 12 GPUs in 8U of rack space, instead of just 7...

[LegolasProudhon]

That looks like a really nice system as well.

One thing to note, the Gabu system is 1/2 depth, letting you put 14 GPUs in 8U of a standard 4 post rack (or you could use 2 two post racks).

http://static.squarespace.com/static/53090978e4b091b1a7927a43/t/53650d82e4b0a8d04d93f120/1399131524947/?format=500w

This really only matters if you want to maximize your density and have control over your space (or are in a space without cold isle/hot isle separation, pretty common in a lot of locations). If you had control of your space you could have 2 cold isles and have a warm vent directly out the top.

Also, I would want to test the thermals on the 4U system. It looks like it will be very hard to push a large volume of air through the back of that system once two power supplies are installed (even with six 120mm fans).

The Gabu system has six 140mm fans and lets the GPUs vent directly out the back of the chassis. This conforms with standard GPU designs and should greatly increase airflow.

In all cases its really hard to say what will happen without comparative testing.
