(FC EC3S - PMC 81605Z)
Learn about the specifications and operating system requirements for the feature code (FC EC3S - PMC
81605Z) adapter.
Overview
The PCIe Gen3 SAS/SATA RAID Adapter is a low-profile, PCIe generation-3 (PCIe3) x8 adapter with a 1
GB protected write cache. The adapter has four internal connections each of which has four x1 ports,
allowing it to support up to 16 drives. The adapter supports RAID (0, 1, 1E, 5, 6, 10, 50, 60), Hybrid
RAID (1, 10), and the hot plug of its attached drives. The adapter's super capacitors provide protection of
the write cache in case of power loss.
Note: The adapter can connect to the 12 internal (front) disk bays on the 8348-21C. SATA devices are
supported at up to 6 Gb/s per port.
For details about slot priorities and placement rules, see "PCIe adapter placement rules and slot priorities
