PCIe2 1.8 GB Cache RAID SAS Tri-port 6 Gb Adapter (FC 5913; CCIN
57B5)
Learn about the specifications and operating system requirements for the feature code (FC) 5913 adapters.
Overview
The PCI Express (PCIe) generation-2, 1.8 GB Cache RAID SAS Tri-port 6 Gb Adapter is a large cache
PCIe2 SAS adapter that provides high-performance capabilities and supports the attachment of
serial-attached SCSI (SAS) disks and SAS solid-state drives through mini SAS HD (high density)
connectors. The feature code (FC) 5913 has a 1.8 GB write-cache. The adapter must be installed in pairs
and must be used in a high availability, multi-initiator RAID configuration with two adapters in
dual-controller mode (Dual Storage IOA configuration). Two FC 5913 adapters provide additional
performance and adapter redundancy with mirrored write-cache data and mirrored RAID parity
footprints between the adapters. If the FC 5913 pairing is broken, then the write cache is disabled.
Integrated flash memory with capacitors provides protection of the write cache in case of power failure,
without the need for batteries as were used with previous large cache adapters.
To provide the highest bandwidth between two paired feature 5913 adapters for the mirroring of cache
data and parity update footprints, a SAS Adapter-to-Adapter (AA) cable is required by default on the
third adapter port until maximum device quantity attachment is required. When all three connectors are
attaching SAS drives, the communication between the adapter pair is performed through the SAS fabric
via the I/O drawer and cabling.
The FC 5913 is a single wide, full-height, short adapter.
Every FC 5913 requires another 6 Gbps SAS RAID adapter (FC 5913) on this server, or on another server,
which pairs with the SAS RAID adapter and enables the onboard caches to function. See Figure 19 on
page 46 that shows the FC 5913 adapter.
Systems running the AIX or Linux operating systems support either having both 5913 features in the
same system or partition, or in two separate systems or partitions. Systems running the IBM i operating
system do not support the pairing of adapters on different servers or different partitions, so both the 5913
features must be installed on the same system or partition.
For details about slot priorities and placement rules, see the PCI adapter placement topic collection for
your system.
