June 3, 20179 yr I have a few unRaid servers with 8-15k passmark cpu scores and tons of ram... looking to build something smaller that can manage 10-15 disks in an jbod box, only as a file server. what is the minimum I can get away with and not bottleneck. need to be able to feed 1-3 clients full gigabit loads and not get limited by cpu during parity checks. thanks!
June 3, 20179 yr With single parity I think you'd be hard pressed to find anything 64-bit capable that would be underpowered.
June 3, 20179 yr Community Expert I'd say any dual core Sandy Bridge or above, 4GB RAM, you could go lower on the CPU for NAS only but since you can get those CPUs for like 20$ and they are much more efficient than older ones that's what I would use (and I do actually use on some of my NAS only servers).

June 3, 20179 yr Community Expert Are you intending to run dual parity? Dual parity does require a bit more CPU horsepower or you will have a bottleneck during parity checks. (I would consider dual parity a must with a 10-15 drive array.)
June 4, 20179 yr Community Expert Unless for a big array, like with over 20 devices, a dual core still enough even with dual parity, e.g.: Sandy Bridge Celeron G540 - Dual parity with 14 disks total - CPU usage during parity check is < 50%
