Low power CPU (Intel Atom) to control RAID1 array (mdadm) [solved]

graysky · 2013-09-30 10:06:43

Can anyone comment on the CPU overhead associated with using a low power CPU such as an Intel Atom to function as a NAS running software raid1 (mdadm)? Will it limit I/O?

Logic says raid0/raid1 should not be much of a problem since you are splitting/dupplicating data without doing any or almost any math, raid5 or others that need to calculate parity information can be a problem with atom cpus I believe.

Maybe you should check review sites for NAS boxes reviews, most come with atom cpus inside and will probably give you a good idea of how your specific cpu model will perform.

Good idea, thanks.

Atom 330 works fine when copying over nfs; CPU usage is minimal.

I thought so. I have an Atom 330 system (but not as file server). As for filesystems, jfs works well with that cpu because it seems to have a lower cpu demand than xfs/ext4.
