Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. To check for operating system and partition requirements, see one of the following links:

PCIe3 12 GB Cache RAID + SAS Adapter Quad-port 6 Gb x8 (FC EJ14; CCIN 57B1)
Learn about the specifications and operating system requirements for the feature code (FC) EJ14 adapters.
The PCIe3 4-port 12 GB Cache RAID + SAS Adapter is a PCI Express (PCIe) generation 3, x8, single-wide,
full-height, short form-factor adapter that provides high-performance capabilities and supports the
attachment of SAS hard disk drive (HDD) and SAS solid-state drive (SDD). A pair of FC EJ14 adapters
are required to provide additional performance, mirrored write cache data and adapter redundancy. If the
FC EJ14 pairing is broken, then the write cache is disabled. Integrated flash memory with super
capacitors provides protection of the write cache without batteries in case of power failure. FC EJ14
effectively provides up to 12 GB of write cache that uses compression of 4 GB of physical cache.
The adapter provides four Mini-SAS HD (high density) narrow connectors for the attachment of SAS
drives in the 5887 disk drive enclosure (IBM EXP24S SFF Gen2-bay Drawer) as shown in Figure 42 on
page 94. Specific SAS cables with HD narrow connectors are used to attach to the 5887 disk drive
enclosure. To provide the highest bandwidth, two AA SAS cables with HD narrow connectors are used to
attach the two paired FC EJ14 adapters on the third and fourth adapter ports (T2, T3) to communicate
status and cache content information. Both AA SAS cables are required unless 3 or 4 ports are being used
to attach the SAS drives. When all connectors are attaching SAS drives, the communication between the
adapter pair is performed through the SAS fabric by way of the disk enclosures and cabling. A maximum
of 96 SAS devices are supported using four 5887 disk drive enclosure. The SAS devices can be all HDDs
or can have up to 48 SSD + 48 HDDs (HDDs must be on the 3rd and 4th ports). They can have a
maximum of 72 SSDs with no HDDs and must have an AA cable on the top port. If there are over 48
SSDs, then no HDDs can be attached.
The adapter provides RAID 0, RAID 5, RAID 6, RAID 10, RAID 5T2, RAID 6T2, RAID 10T2, and OS
mirroring (LVM) for the AIX, Linux, and VIOS operating systems. Under the IBM i operating system, the
adapter provides RAID 5, RAID 6, OS mirroring, and data spreading. RAID 10 is supported by IBM i
Version 7.2 or later.

or SAS RAID controllers for Linux topics for more information and important considerations for
multi-initiator and high availability or dual storage IOA configurations.
