[CentOS] hardware raid vs fake raid
Hi, Does anyone know how I can find out if an ibm serveraid 8k sas storage controller (zero channel RAID) is a real hardware RAID controller and supported in the standard CentOs kernel or is it a fake raid controller. I am trying to decide if I should get the serveraid controller or go get a 3ware controller.

Tom, The ServeRAID 8k s a real hardware raid controller, is has 256 MB of cache I think and a battery backup. So in this case there is no need for a 3ware controller. On the IBM website you can also find a commandline tool (called arcconf) that allows you monitor and configure the controller inside Linux.

Maybe in this league, cheating customers is not so common. Does anybody know a SAS/SCSI raid card which does hidden software raid instead of hardware?
