5u "RENDER CUBE"

This looks very promising for high density render farms. 256 Xeon cores in 5u!

http://www.anandtech.com/show/6257/...e-compute-cards

http://www.theregister.co.uk/2012/0...15000_analysis/

At $83,000 fully loaded this is way out of reach for your typical home "render closet"

Does anyone have one of these to run some benchmarks on?

kind of a waste of cash when you can get the same cpu power at a fraction of the cost with non-Xeon chips.

this looks great if you plan on creating a bunch of virtual servers, but as a brute force rendering solution these are always a waste of cash.

I beg to differ. I built render farms for 2-3 of my clients. we always hit the "price vs. performance vs. density" formula.

"If your NODES are cant be FASTER, you need more OFF THEM."

The same variables comes up:

what is the Factor of speedup over what we do now? (capacity)

what is that Cost vs. capacity equation? (cost per node)

okay I will spend (ballpark 10 node farm) what do i get? (production output)

WHAT IS THE NEXT STEP?????

(money amounts are rounded, and Hyper Threading NOT being taken into account, and I'm not going BENCHMARCK thumping here)

The last question is KEY to building a bigger render-farm. so you end up looking at 4 options:
1. more beige boxes on shelves
2. 1 1U servers xeons
3. blade systems

Easy if you have unlimited space....

or Think of it this way. you ONLY have 2 25u servers racks to fill.

option 1 = 10 beige(6core) boxes on shelves $10K (1 core = $166)
option 2 = 25 1u xeon(8core) nodes $35K (1 core = $175)
option 3 = 4 x 10U 16node xeon(8core) $130k (1 core = $254)

You pay a Premium for DENSITY.....

now look at this new option:
"...256 Xeon cores in 5u!" for $83k

option 4 = 10 x 5U Xeon(256core)n core xeon $830,000(1 core = $324.21)

yes your paying over 8 x as much as option 3

BUT your getting 2560 cores vs 512 cores thats a 500% PERFORMANCE improvement.

In conclusion, Unlimited space i7 beige boxes make the most FINANCIAL sense. But if you need to pack in the Absolute HIGHEST amount of computation power into the smallist space, these blade and 'hyper blade solutions make ALOT OF SENCE'

But the reality is with online render farms becoming more and more affordable, this is becoming a dying argument. 3-8 node render farm (per artist) in house makes a HUGE impact. Once your past 15-20 nodes the expense is just not justified, unless you have enough jobs to keep the farm burning going 24/7.

Just what i have seen.

the power bill would be ridiculous.

Hey man,

I think this one belongs in the hardware discussion.

This type of hardware really isn't meant for render farms. If your looking just for CPU power, there are far more effective solutions.

Like i said in my original post, i know this is is a commercial IT project probably ment for virtualization servers. These solution rarely win the "bang for the buck' test. But if your as users we Win with higher density with lower pay-to-render rates.

Hey man,

I know its fun to spec out crazy systems like this, but this type of set-up just isn't practical for a render farm.

If your looking to spend 830K on a rendering solution, you should really call a professional.

the ROI in that setup is non-existant... i'ld take half of my budget and strike a deal with a cloud render serivce, and the other half and distribute bonuses to staff...
