I'm quite a noob, I'm trying to set up as a study machine an old HP ProLiant DL385 G1.
I've configured a RAID 5 out of six SCSI 3.5" HDDs using: - Smart Array 6i controller; - (4 x SCSI Ultra320 36,4GB disks, 15K) AND (2 x SCSI Ultra3 36,4GB disks, 10K), all on the same local SCSI bus.
Now the disks should run on the SCSI bus at most @ 10K, 160MB/s, as imposed by the slowest Ultra3.
If I put the two groups of disks on two different SCSI local buses, would the overall performances of the array be improved? The two-buses configuration requires an optional terminator board...
