The PCI-X DDR Dual -x4 Port SAS RAID Adapter is a long-form factor adapter for high-performance, serial-attached SCSI (SAS) applications. FC 5902 is always to be used in a high availability, multi-initiator RAID configuration using two adapters in dual-controller mode. Two 5902 adapters provide for mirrored-write cache data and mirrored-RAID parity footprints between the two adapters. If the 5902 pairing is broken, then write cache is disabled. With correct cabling, multiple wide ports are used to provide redundant paths to each dual port SAS disk. The adapter manages SAS path redundancy and path switching should a SAS failure occur. The adapter is a 64-bit, 3.3 V, bootable SAS adapter that supports RAID levels 0, 5, 6, and 10. The adapter pairs are used primarily with EXP 12S SAS disk expansion drawers, FC 5886, but can also be connected to the internal disk drives in the system unit using the appropriate split disk backplane feature and cabling.
