SAS Controller Daughter Card
Your system includes a dedicated slot on the sideplane for an internal SAS
controller daughter card that provides the SAS storage subsystem for your
system’s internal hard drives. The controller supports either all-SAS or all-
SATA hard drive configurations and also enables you to set up the hard drives
in RAID configurations as supported by the version of the SAS controller
included with your system.
