This is some nice airflow setup, can you be more specific about pulling the AC air from the ground?

This is a typical DC airflow diagram bro, most if not all data centers are designed like this ...
I mean what are the most cost effective ways of data center air cooling systems?

The air is pulsed from the ground through grilled plates that replace the normal floor plates and pulled by negative pressure, made from the racks intakes and the hot aisle separation/ceiling air-pull, this is the most efficient design as air cooling goes, and the sad part is that you have plenty of datacenters that aren't respecting it fully, even though it has been invented for nearly 25+ years now. You also have some system variant, but the principles are the same.

@ m1n1ngP4d4w4n -  Thanks...........just getting warm up bud.  Got more crazier / sexier prototypes coming out of my lab in a few weeks

Damn man, i would dream to have enough means to realize all the craziness going through my head, at least i can vicariously realise a portion of that through you ahah  Grin

yun - this air flow strategy -- does it work?

This is respecting the optimised air flow scheme you can find in any good datacenters, the principles of cold / hot aisles, in the cold aisle in front of the racks, you bring AC air from the ground, then this air get sucked up from the front of the rack, pass through the servers, and get rejected in the back in the hot aisle, where it's sucked up from the ceiling ventilation system. The tarp at the top of the rack serve as a separation between both aisles for optimised air flow and balanced negative pressure

here is a schematic explaining this system.



Yun does it with normal air circulation instead of AC air, but the principle is the same.

@yun9999 can you make a photo of the 42u rigs inside? Cheesy
Also what kind of "chinese cases" are that? I want to build more rigs but i dont know how i can place them in a 42u cabinet.

Thanks Smiley

There's no name for these Chinese Rigs.  They just call it Open Air Rig.  I was helping them sell these rigs for a while to get the goodies for the Community at cheap prices of $99-129 shipped depending on QTY  vs $179-249 retail price.  However the Vendor got greedy and started jacking up the prices and also made it harder for me to direct ship to people as they required a min of 11 vs 4.  It also added too much work as people would ask me so many technical and sales questions as if I was a reseller.  So I stop.  Was not worth the hassle for me but I did hook up over 60 different people prior to stopping.

It's a sexy design but you have to build and keep the fans on even though they are very weak, they do Act as support beams for the cheap plastic.  I won't name any names but I'm sure he's reading this................When you don't listen.................you end up with bendy Chinese RIGS!!!  Hahahaha.    So if you do decide to buy from Ebay, take my advice, keep the fans installed or even replace with stronger fans, but use it.  


Here's a picture of the rear of my Rack.  This is with the 4 ft long Dell PDU.  If it's APC, it's mounted horizontally and I put it on the top portion of the rack where I have 3.75U+ of empty space.

@ duduti - Nice work.  Very clean.  Once you see my Pico setup, I think you will like it.  It makes cabling so much more simple and clean.  Just waiting for all the necessary parts.  Finksy got the 150 Picos in already.  I just need the custom cablings.


Yeah, i can't wait for your pico setup. This is really a good improvement

@ Citronick - Perhaps next month.  I have 4 more SRR coming.  I might use 1 for the custom design stuff including the Racing  MB.   Right now focusing on Custom Prototypes.  

@ Crypto - I don't think it's that straight forward bud.  I've used splitters before.  I highly doubt you can just connect a few of these into your MB and be able to recognize all

@ Citronick - Haven't had the chance put this Motherboard into much action.  It's a pain in the A$$.  You have to use another supported CPU to flash the board, and each time you add or remove GPUs, it turns the system on and off multiple times like it's about to break.  Support for BIOSTAR is one of the worst I've seen.  Contacted the Cali office and the guy doesn't even know how to reset CMOS, he told to send it in for RMA.   This board is just trying me nuts.  I got Windows to work with 5 not 6 cards.  Maybe I need to try another board, just no time since I have to flash it.  Simple OS doesn't like more than 1 GPU on it.  I think I might return 10 of them and just keep 5 for play.  Wasted way too much time on it.  

@ Marvell - Cool, so there is HOPE!  However if it can't also work with Simple, it's kind of a weak MB.

@ Whyme - Prove it.  Splitters don't always work and it's not as easy as you think.  Windows is definitely not the answer either.

@ CryptoWatcher420 - I did check out that link but it say max of 4 GPU per Cluster or is Max?

@ bughatti - Don't blame him but I would love to buy that solution to put in my Play build.  Got the 4KW I can easily power more than 16 GPUs.



I will leave this mobo alone then because I too lazy to spend a sauna afternoon in the warehouse.... furthermore SRR is kind off funky on the mobo - unlike the H81s.
Its running fine for my 4-riggers - may do some consolidation of the Nanos to 6 and 7s riggers, since using Optiminer v1.7 for ZEC saves me at least 100w per rig.

@WhyMe.... I have tried this experiment last year, not that straight forward to just arrange an array of these splitters and expect double the amount of GPUs. Windows maximum 7 GPU and 1 x splitter only. Anything more than that -- will need Win10-Ent hacks, special drivers and Linux. Would love to see how you do it though - I am assuming that you have actually done it

its 4 gpus per cluster and theres 4 clusters per pci-e host card, 16 gpu per x1 slot, think a use for that 4k psu for just one motherboard with many many many gpu's lolz

god this 4mhs bug is annoying having to reslot 5 times per restart.

anyone know why a lot of these saphire cards disply black screen while some work? cant even display anything with half these cards


I have a lot of Sapphire cards (R9-Nanos and RX480s) -- yes it was so frustrating - this Windoze; I fixed it using a HDMI dongle.

Now, all my rigs are running headless on smOS Linux, and I don't have that issue anymore.

geeze what motherboard can do 16 gpus?

With any standard motherboard and some pcie multiplier you can do same thing !

Its been asked many times and he is not giving up the gold.  The motherboard is a MSI Z97 gaming 5 but he did his own bios and very low level linux kernel changes.

there was this dude who got hold of a 2k usd extension-motherboard supporting full 16x PCI slot for deep-learning / GPU cluster turned into a bad-ass ETH rig. I think the project was posted in Claymore ETH thread sometime last year (see link below) -- Claymore even had to put a new revision to make his miner support more than 12 x GPUs to support it. But... really $2k motherboard? Really not worth it. Better to do multiple 7xGPU or 8xGPU rigs.

unless its something like http://amfeltec.com/products/gpu-oriented-cluster/
which I have to say is pretty neat, but im sure its not cheap
