Where to buy blade chassis?

post #1 of 27
Thread Starter 
Been assembling some rendering machines so I can more effectively work from home. Nothing crazy, i7 2600ks that I'm overclocking to 5ghz and 16GB RAM.

At our office they've got around 500 render blades which I'd always figured were high end offerings from Dell or HP etc. Turns out they are basically just trays with motherboards installed into them and a handle to slide it in or out of the enclosure.

Anyone here know where to buy such trays? They're more or less the height of the ports of the back of a motherboard and the ports are oriented towards the front of the chassis for ease of access.

Doesn't sound like actual blades to me at all - a 'proper' blade is a lot more than just a tray with a mobo on. They basically look like a full blown server, just a lot smaller.

Not sure where to get your trays from - where did your company get them originally?

First off, with real blades there is no overclocking, they are some what proprietary. Basically if you buy Dell blades, expect to have to use a Dell enclosure.

You should go through either HP or Dell's website to spec out and purchase the blades, or go through an authorized reseller who is an expert in the product line.

Yep, blades are proprietary and very expensive. It would be way cheaper to just build a couple of small form factor rigs, and rig them all up to a Gbit switch.

If you want it even smaller, perhaps look for rack-sized enclosures (19" wide). Something with a height of 2u should fit. I think Supermicro sells them, although you might need a beefier PSU.

Are you talking about actualy blade servers or just systems built to fit 1U trays?

You can get cheapy Norco or Athena 2U cases, and many of them will work with standard ATX supplies (although you need to get a PSU with 80mm fans on the front & back, rather than a 120+mm fan on the bottom - something like an Antec Greenpower or similar).

For a render node using CPU power only you won't need a particularly beefy supply though - single CPU systems wouldn't need more than 300W even when highly clocked as you only need a tiny GPU.

I think OP means 1u or 2u cases not blades.

I'm having flash backs and panic attacks to sun blades now ...

If you are talking about standard form factor cases to fit into a rack, such as 1U, 2U, 4U etc.. and you want to overclock and assemble it your self then your best bet could be to get 4U cases.

With 1U and 2U you can fit more servers into the rack, but with 4U height of the CPU coolers, the GPU's will be much less of a concern; PSU's will also be easier/cheaper to get a hold of if you are using standard ATX PSU's. It also would likely be quieter since you could use 120mm fans instead of little 40/60mm fans.

How many systems do you want? Have you considered scaling out (4x single socket) versus scaling up? (2x dual socket, or 1x quad socket) How big is the rack?

Maybe the OP was talking about a scalable multinode system from hp? Still would not be able to OC.

For whatever reason, I was under the impression that 'blades' were simply high density computing installations whose goal is high performance applications and processing speed (as opposed to a rack of servers dedicated to hosting VMWare) for things like data processing. Didn't think it mattered what the case designs were like or who made them...long as you had as much computing power possible per square inch.

Our render farm machines at the studio aren't OC'd of course because that's pretty much impossible in a high density setting like that, however for the scale of what I'm doing, I could pull it off I think. Doubt I'd go higher than 10 machines for personal work.

The chassis they have here in our farm aren't really 1U which is why I'm asking about these things. You know how blade enclosures might total 24U, but internally they are subdivided in non-1U divisions? It's sort of like that. Each of these trays isn't much wider than the motherboard itself.

For clarification though and to avoid looking foolish in the future...are blades not simply a set of high performance and high density computers? I don't understand what happens between a tiny chassis holding high power CPUs and the offerings from Dell/HP that makes them into blades and the former into...well whatever you'd call it.
