BUILD C2750 vs C2550 vs ? Xeon

[cadamwil]

So I think in another thread it has likely been shown that someone is running FreeNas 9.2 on a C2750. So my next question, which is better Octo core low power 2.4 Ghz bursting to 2.7 with 32GB of Ram or unknown Xeon with 16GB of Ram? If the 32GB is better, is the Octo core overkill? Will FreeNAS even use all of the cores?

There is no "correct" answer. Some situations will benefit from a faster CPU, some will benefit from more RAM.

It's important that you know which is better for your situation and buy appropriately. Just helped someone earlier this week build a 256GB RAM, 20TB, ESXi datastore. Can saturate 3x1Gb links simultaneously! The plan is to run more than 20 VMs from the FreeNAS zpool.

It is unlikely I will need much performance on anything but rebuild. Worst case scenario would be pulling an ISO of 50GB, writing an ISO of 50GB (at Blu-Ray speeds) saving 8 HD TV streams and reading 4 hd streams. That would be a worst case scenario only likely to occur in testing. Initial rollout will be 4 WB 4TB Reds, with expansion to 8 drives if needed.

Does anyone have a list of processes or functions that are CPU or ram intensive? Reading on the build guide it seemed like the mantra was RAM, RAM, and more RAM.

I think CIFS/Samba used to be single-threaded - not sure if that still applies for the new Samba 4 implementation.

I think we haven't had somebody testing the new Atoms with FreeNAS yet, so you might run into compatibility issues. But I'd love to see somebody trying ;)
