I've installed, and am running RHELv4 with 2 9550SX SATA-RAID controllers. Prior to that, I was running on an 8000 series controller without problem but was only using JBOD. However, since I paid for the hardware capabilities of the 9550SX I am using their RAID utilities and not using software RAID. And, in case someone asks, I am running with battery backup on my controllers.
