Quoting Chris Heiner <cheiner@xxxxxxxxxxxxxxxxxxxxx>:
Last week we tried to install Centos on a brand new HP ML150 G2 with AIC-8130/ Marvell SATA Raid card and it was a no go. We tried a few other flavors of Linux as a test and all had trouble as well. Unfortunately time didn't permit so we opted for a Windows solution to get the box into production.
You sure that Marvell thing was hardware RAID? Currently, Marvell SATA controllers are not supported by stock Linux kernel. There's a driver source somewhere on Abit's FTP server that should work (more or less) stable on 2.6 kernels. I'm talking here Marvell SATA controllers (including fake-RAID ones), not SATA based hardware RAID controllers (if Marvell makes any of those at all).
What cards have worked for you?
Adaptec and 3ware solutins seem to work nicely. With Adaptec, I'd be carefull to get aacraid based card, not I2O. In my very limited experience, 3ware cards were not as flexible as Adaptec's aacraid based cards. The 3ware you configure once and that's it. With Adaptec, you can migrate data from individual drives into RAID arrays, expand arrays (even RAID-5), change RAID levels (migrate volume from for example RAID-1 to RAID-5) and so on. All while the host is up and running. Well, at least with those I had in my hands (like for example the SCSI based 2200S).
