They'll take 3Ware cards in the expansion slots, but they typically have SCSI SCA bays, not SATA bays. Check with HP and see if you can get DL3xx series SATA bays (I assume these are DL3xx series)? If you're worried about reliability, buy 10,000rpm SATA drives that typically roll off the same line as their SCSI/FC counterparts. I'm fairly sure the 73/146GB WD Raptors are fabbed by Hatachi and match their specs. > Let me know in terms of CentOS 3 and/or 4 please. Have run RHL9/RHEL3 on the DL1xx and 3xx series, no major issues. It really comes down to the _exact_models_ and _revisions_ (part numbers will do). Do you have those? -- Bryan J.
