(#5902) - PCI-X DDR Dual - x4 3Gb SAS RAID Adapter

The PCI-X DDR Dual - x4 3Gb SAS RAID Adapter is a long form factor adapter and is an excellent solution for high-performance applications requiring two adapters. Two #5902 provides for mirrored write cache data and mirrored RAID parity footprints between the adapters for superior availability. With proper 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. RAID levels 0, 5, 6, and 10 are supported. Primary use is with FC 5886 EXP 12S SAS disk expansion drawers. FC 5902 is always to be in used in a High Availability configuration using two adapters.
