I agree, the LSI megaraid cards work much better then Adaptec cards. The only downside is that megaraid cards do not have good administration tools at all.

Yes, the MegaRAIDs are "real" hardware RAID (a quick look at the specs shows the onboard IOP). I honestly don't know how they perform in RAID5 (I use mine for a cluster head node, just doing RAID1), but I'd make sure you get the PCI-X (or PCIe) versions rather than the regular PCI ones. The driver support is quite good, but the monitoring is a little tougher. I've been shying away from Adapted for a while now, so I have no experience with them at all. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
