Learn about the specifications and operating system requirements
for the 5902 adapter.
Overview
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.
