PCIe3 x8 cache SAS RAID internal adapter 6 Gb (FC EJ1D and EJ1M; CCIN 57D8)
Learn about the specifications and operating system requirements for the expanded function PCIe3 x8
cache SAS RAID internal adapter 6 Gb (FC EJ1D and EJ1M; CCIN 57D8) that is integrated with the
composite storage backplane in the 9009-41A, 9009-42A, or 9223-42H system.
Overview
The expanded function PCIe3 x8 cache SAS RAID internal adapter 6 Gb is an internal PCI Express
generation 3 (PCIe3), serial-attached SCSI (SAS) Random Array of Independent Disks (RAID) adapter
integrated in the 9009-41A, 9009-42A, or 9223-42H system. The PCIe3 x8 cache SAS RAID internal
adapter 6 Gb (CCIN 57D8) is part of the composite feature of the expanded function storage backplane
(FC EJ1D and EJ1M). The adapter contains the SAS RAID controller.
A pair of these expanded function internal adapters is pre-installed in the dedicated internal PCIe3 x8
slots P1-C49 and P1-C50 in the 9009-41A, 9009-42A, or 9223-42H system. The expanded function
composite storage feature (FC EJ1D and EJ1M) provides the following features:
• An expanded function storage backplane (CCIN 6B64 or 2D35) that provides slots for 12 numbers of
2.5 inches small form-factor (SFF) hard disk drives (HDDs) or solid-state drives (SDDs) with an RDX
drive bay, or 18 numbers of 2.5 inches small form-factor (SFF) hard disk drives (HDDs) or solid-state
drives (SDDs) without a RDX drive bay
• A pair of the expanded function PCIe3 cache SAS RAID internal adapters (CCIN 57D8) that are installed
in the slots P1-C49 and P1-C50.
• Two mini-SAS HD cables that attach to the expanded function storage backplane. For information, see
Front SAS cable.
• FC EJ0W provides a mini-SAS HD cable with two external SAS ports that is installed in the system rear
bulkhead in the slot P1-C6. For more information, see Rear SAS cable.
The PCIe3 x8 cache SAS RAID internal adapter 6 Gb has a data read-write speed of 6 Gbps and a real
write cache of 1.8 GB. With a 4:1 cache compression, this expanded function adapter provides an
increased cache of 7.2 GB and increases the storage system performance. The write cache contents are
protected against power loss with flash memory and super capacitors and removes the need for cache
battery.
The two mini-SAS HD cables connect each of the PCIe3 x8 cache SAS RAID internal adapter 6 Gb to the
two SAS ports on the storage backplane. The expanded function internal adapters supports both SFF HDD
and SSD drives to be used in Dual Storage IOA RAID configurations. The supported RAID configurations
include: RAID 0, 5, 6, 10, 5T2, 6T2, and 10T2. JBOD disks are not supported in a Dual Storage IOA RAID
configuration. The expanded function storage backplane does not support the split storage backplane
configuration.
Each of the internal adapters provide a rear mini-SAS HD connector that attach to the mini-SAS HD cable
which has two external SAS ports on the other end. In the 9009-41A, 9009-42A, or 9223-42H system,
the external SAS ports are installed in slot P1-C6. The external SAS ports are used to attach a FC 5887, FC
ESLS, or FC ESLL drive enclosure. Only one drive enclosure is supported by the expanded function internal
adapter pair and must be in zone mode 1. The external SAS YO cables that are used to attach a FC 5887,
FC ESLS, or FC ESLL disk drive enclosure to the rear SAS ports must not exceed the maximum supported
length of 3 meters.
Systems running the AIX or Linux operating system support both adapters RAID controllers owned by the
same or different partitions. AIX or Linux also provide mirroring (logical volume manager (LVM))
