They seem to be moving upscale these days. Regarding the Marvell drivers, I had good luck with the 'sata_mv' driver in Scientific Linux 6 just yesterday, running a pair of 4-port PCIe-x4 Tempo 'Sonnet' controller cards. So it appears someone has fixed that particular driver. I've decided to stick with those cards rather than re-install the Supermicro/Marvell SAS/SATA 8-port controllers, which use the 'mvsas' driver that I had problems with on the RHEL-6 evaluation distro. So far, SL-6 has performed very well, all RAID-6 arrays re-synced properly, and running concurrent forced fscks on eight arrays was very fast (because the ext4 filesystems were still empty :-) ). I think I'll stick with SL-6 as the VM host OS, but will use CentOS for the guest VMs. CentOS-5.x will do fine for now, and I'll have the luxury of upgrading guest OSs to CentOS-6 as the opportunity arises.
