I have a Dell PowerEdge 2950 with 6 SAS disks and a PERC 5/i controller what won't do RAID 6. I plan to have 2 drives as RAID 1 for the OS, and the remaining 4 as RAID 6. Granted the PERC can do RAID 1, I'm tempted to do everything via software RAID. Thus, if anything goes wrong with the controller, I just need to obtain a new SAS controller and I'm back up.
4 disks in RAID 6? Isn't this a bit overkill? You would use half the space for RAID checksums. If it were me, I would: Partition all drives identically with a 200M partition 1 and the rest as partition 2 Use sda1 and sdb1 in RAID 1 as /boot Use sd[cdef]1 as swap in RAID 5 Use sd[abcdef]2 as / in RAID 5 You could use RAID 6 for /, but then you're not 100% safe if you loose disks 1 and 2 simultaneously.
