I have a repurposed server. Before the repurpose it was an ESXi host so it had 6 2TB hard drives and an Adaptec 6805 SAS RAID card (and 2 6-core processors and 128GB ECC RAM which is another problem) but now decommissioned as a VM host it is receiving a desktop version of Ubuntu.
During the VM Host days I found out that the RAID card have a bit of personality though, requires a fan on it to perform reliably, and if the fan get clogged by dirt it can lock up from time to time.
Now how should I manage the drives in its most efficient way? I'd like to use RAID-10 or RAID-5. The motherboard do have enough ports to hold the disks.
- Get rid of the RAID card and build an array using the onboard soft RAID Option ROM and
- Keep the RAID card and build the array there.
- Keep the RAID card but use it only as a JBOD, and build the array in
- (Joke option) sell the drives and the RAID card (and half the RAM) - one 2TB spinning platter drive is more than enough.
