PCIe LP Dual - x4 SAS Adapter (FC 5278; CCIN 57B3)
Learn about the specifications and operating system requirements for the feature code (FC) 5278 adapter.
Overview
The FC 5278 (PCIe LP Dual - x4 SAS adapter) is the low-profile adapter same as the FC 5901, which is
the full-height adapter. The names of the two adapters are:
v FC 5278: PCIe LP Dual - x4 SAS adapter
v FC 5901: PCIe Dual - x4 SAS adapter
The PCIe LP Dual - x4 SAS adapter is a low-profile, short form factor adapter for high-performance and
high-density, serial attached SCSI (SAS) applications. It supports the attachment of SAS disk, tape, and
DVD by using a pair of mini SAS 4x connectors which allow the eight physical links to be used in
various narrow and wide-port configurations. The adapter does not have write cache.
The adapter is a 64 bit, 3.3 V, bootable SAS adapter that provides RAID 0, 5, 6, and 10 capability. Some
RAID level support is operating system dependent. The adapter provides RAID 0, RAID 5, RAID 6, and
RAID 10 for the AIX and Linux operating systems. IBM i operating system provides mirroring and data
spreading capability. FC 5901 does not support the RAID 5 and RAID 6 configurations. The adapter does
