I have a Redhat 8.0 server running Postfix and Apache. I'd like to beef up the disk system.
I know a true SCSI RAID 0,1 or 5 would be the best bet, but it's cost prohibitive right now.
I was wondering, if anyone out there can tell me, how much stress a SCSI controller with SCSI drives, controlled by the Linux software would put on the processor? Would the advantages and disadvantages cancel each other out?
What about ATA 133 or SATA RAID? Should these be a last resort? I read that SATA (serial ATA) is built as a cost effective replacement for SCSI, though it's not much fast that ATA 133.
I'd like to use RAID 5, if possible.
Any thoughts or opinions are greatly valued!
