Hi list,
I'm thinking about buying some (20) Silicon Mechanics Rackform iServ
R308.v2 compute boxes for my EDA apps compute grid. They'd be running
RHEL5. I'd probably get them with an X5660 and 48gb of ram. Not too
worried about dual power supplies, since they're compute box not
servers. Link -

I've generally had good luck with Silicon Mechanics; though I have
never bought this particular variant before.
Where I'm buying 20 of them I'm just seeing if anyone has any
experiences I should be aware of:
- Are there other vendors I should consider that I don't know about?
- Do you have horror stories about anything (this vendor/X5660
processors/ghosts)?
- Do you have non-horror stories about anything (same, etc.)?
- Is the management usable?
It looks like the OEM the Supermicro chassis and motherboard, which is
what we use for our CAD clusters. Good machines.If you want higher
density and slightly more efficient cooling you might look at the
twin-squared line (2 machines per 1U, up to 3 HDD per machine). The
IPMI/KVM is quite usable and functional, allowing most things you'd
want, and the speed is very good. You might check to see what the
maximum size of ram is that it will take unbuffered RAM. The unbuffered
RAM will run significantly faster than the buffered because of the added
latency from the buffers. For CAD, that tends to matter somewhat (it
does for us).
We don't have the silicon mechanics, but we do have a lot of the supermicro.
