The is also the amfeltec gpu cluster and the
http://www.hwtools.net/Adapter/PE4C%20V3.0.html for the more do it yourself
approach. We rendered our student short out using Octane standalone via the
network between 3 machines and it positively flew.
Some usbC external gpu chassis that are now coming out (announced at GDC). For
my MA project I am extending our current machine (which has one 980ti) with two
additional ones using PE4C adapters. (mostly because most of our available
money was spent on the cards)
I have seen cases running 4 air cooled 980tis in a well ventilated case with no
issues. Water cooled does offer performance gains but as has been pointed out
can be a bit of a bugger if you have a card go down.
Kind regards
Angus

External gpu boxes work great with octane, not so well with redshift, due to
the increased communication between cpu, gpu and system memory, it really needs
a decent number of pcie 3 lanes to run at full speed.

Why doesn't someone start building these things directly in an air condition
unit? That would make sense. And it would produce some pretty cool renders...

Yes but also need a bit more custom case so that placeholders for 4 radiators
are near cards :)))

The other option is to get some of this hybrid cards, with cooling included.
There are more expensive, but I guess you won't melt them so easily ;)

Also keep in mind that 8 GPU server requires also 2 Xeons which are lot more
expensive then i7 CPUs.
Put everything on paper and see the math.
Btw I advise highly against water cooling cards for GPU.
First it adds to a price a lot which would better be used on better GPUs, CPU,
more ram....
Also in any case of card failure you are out of whole machine for hours till
you drain system and all the process around it.
With standard air cooled you just plug faulty card out and back to rendering
till you replace or fix.

Hi Adam,
You 2 routes, DIY/MOD or getting a SERVER chassis (more expensive).
SERVER
https://www.youtube.com/watch?v=DhZJ66l82r8&feature=youtu.be
If you are any good at building/modding computers, than you can try buidling
one yourself with the help of geeks from
the internerds..
http://dabarti.com/vfx/building-4xgpu-rack-mount-rendering-node/
One other options is to ask someone like Tom Glimps to build you one:
https://twitter.com/tomglimps/status/710959378799730688
This stuff is watercooled and cards are modded, so not trivial.
I would recommend you could ask on the otoy forum, and join the octane facebook
page.
Good luck, and keep us updated!

Also not much experience with GPU boxes but what I don;t really get is what
takes care of rendering with so many GPUs on single CPU?
For example you have single 5960x CPU and 64GB ram.
Even with 4 cards I've bin locking down CPU at 100% from time to time and also
RAM as well. Talking about computer RAM not GPU RAM.
As it works it renders 4 frames at once, each on 1 GPU.
I really don;t see much room to add fro example another 4 GPUs in attached GPU
box when there is still some work on CPU to be done and RAM requirements for
scenes and all to load.
How would high end CPU that is already maxed out handle additional load?

I dont know much about the gpu boxes, but i would advise you to wait a bit for
pascal to be released. I saw yesterday that amazon was doing clearances on
"games" hardware so i presume it wont be long now as they seem to be clearing
out the shelves.

Hi Softies/Blendies/Houdies etc.
I was thinking about boosting Redshift render power a bit with a gtx980ti or
two.
Does anyone have experience with using external GPU boxes that can be plugged
into their workstations?
It seems like a cleaner, more scaleable and more flexible solution than
stuffing the cards right into the workstation itself.
Any recommendations or advice gratefully received.
Cheers,
Adam.
