I have an IBM Netfinity 7000 M10 and I am trying to get my head wrapped around it's SCSI disk system. I am not very familiar with SCSI systems although I have done a good deal of reading on the subject.
System: RedHat 9.0
Machine: Netfinity 7000 M10
RAM: 2 GB's
CPU Info: 4 - 400Mhz Xion
SCSI Controller: ServeRaid 3H Ultra 2
The ServeRaid 3H card supports data transfer rates of 20MBps, 40MBps, and 80MBps. I have tried all sorts of configurations within the SCSI controller and haven't seen transfer rates better than 28 MBps using "hdparm -t".
Is this good? Bad? This server is sitting idle with nobody by myself logged into it. The drive I am testing at the moment is an Ultra3 36.7 GB 15,000RPM LVD/SE drive. I would assume I would get a better throughput rating than this...
Anything you can throw my way to enlighten me about SCSI disk opimization?
