The IBM® ServeRAID C105 are integrated SATA controllers with software RAID capabilities. It is a cost-effective way to provide reliability, performance, and fault-tolerant disk subsystem management to help safeguard your valuable data and enhance availability.
The IBM ServeRAID C105 is an integral function of the system planar. There is no additional hardware required. It can be enabled and disabled through the system Human Interface Infrastructure (HII) Configuration Utility, which is used to configure controllers, drive groups, and virtual drives, and to perform other configuration tasks in a pre-boot environment. Once enabled, the IBM ServeRAID C105 takes control of all devices that are connected to the planar SATA ports of the server, including the SATA optical drive, if present.
