PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ1F and FC EJ1H; CCIN 57D7)

Learn about the specifications and operating system requirements for the PCIe3 x8 SAS RAID internal
adapter 6 Gb (CCIN 57D7) that is integrated with the base function storage backplane (FC EJ1F) in the
9008-22L, 9009-22A, or 9223-22H system. Adding of another PCIe3 x8 SAS RAID internal adapter 6 Gb
(FC EJ1H) enables the base function storage backplane (FC EJ1F) to be configured as a split storage
backplane in the 9008-22L, 9009-22A, or 9223-22H.
Overview
The PCIe3 x8 SAS RAID internal adapter 6 Gb is an internal PCI Express (PCIe) generation 3 (Gen3),
serial-attached SCSI (SAS) Random Array of Independent Disks (RAID) adapter that is integrated in the
9008-22L, 9009-22A, or 9223-22H. The PCIe3 x8 SAS RAID internal adapter 6 Gb is part of a composite
feature of the base function storage backplane (FC EJ1F). The adapter contains the SAS RAID controller.
The PCIe3 x8 SAS RAID internal adapter 6 Gb is preinstalled in the dedicated internal PCIe3, x8 slot
P1-C49 in the 9008-22L, 9009-22A, or 9223-22H. The internal adapter has a data read or write speed of 6
Gbps.
Adapter caching
The PCIe3 x8 SAS RAID internal adapter 6 Gb does not have a non-volatile write cache. However, Linux
customers can take advantage of a volatile adapter write cache of up to 1 Gb (compressed) for improved
performance. This support is available with the 2.4.10 version of iprutils utility available from the IBM
Linux Power Tools Repository (http://www14.software.ibm.com/webapp/set2/sas/f/lopdiags/
yum.html) and with the latest adapter firmware available from the Fix Central website
(http://www.ibm.com/support/fixcentral/).
Single adapter configuration
This configuration of the storage backplane in the 9008-22L, 9009-22A, or 9223-22H with one PCIe3 x8
SAS RAID internal adapter 6 Gb (FC EJ1F) supports 8 numbers of 6.35 cm (2.5 inches), small form-factor
(SFF) hard disk drives (HDDs), or solid-state drives (SSDs). The PCIe3 x8 SAS RAID internal adapter 6
Gb supports the drives to be used as just-a-bunch of disks (JBOD) or as a RAID array. The supported
RAID levels are RAID 0, 5, 6, and 10. Two mini-SAS HD cables connect the PCIe3 x8 SAS RAID internal
adapter 6 Gb to the two SAS ports on the storage backplane. This configuration with one PCIe3 x8 SAS
RAID internal adapter 6 Gb does not split the disks in the storage backplane.
Two adapters configuration
To enable the split storage backplane, another PCIe3 x8 SAS RAID internal adapter 6 Gb (FC EJ1H) must
be installed in the other dedicated internal PCIe3 x8 slot P1-C50. The same storage backplane as in FC
EJ1F is used in the split storage backplane configuration. The two mini-SAS HD cables connect each of
the PCIe3 x8 SAS RAID internal adapter 6 Gb to the two SAS ports on the storage backplane. The 8
drives are then split into 2 sets of 4 drives (HDDs or SSDs), each controlled by one PCIe3 x8 SAS RAID
internal adapter 6 Gb. The split storage backplane configuration supports the drives to be used as
just-a-bunch of disks (JBOD) or as a RAID array. The supported RAID levels are RAID 0, 5, 6, and 10.
The preinstalled PCIe3 x8 SAS RAID internal adapter 6 Gb in slot P1-C49 controls drives, D1, D2, D3,
