v A pair of the high-function PCIe3 cache SAS RAID internal adapters (CCIN 57D8) that are installed in
the slots P1-C49 and P1-C50.
v Two mini-SAS HD cables that attach to the high-function storage backplane.
v 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.
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 high-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 high-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. The high-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, 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 high-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))
capabilities. The dual controllers support the Easy Tier
automatically move hot data to attached SSDs and cold data to attached HDDs in the AIX or Linux
Systems running the IBM i operating system do not support the two adapters being owned by different
partitions, nor the Easy Tier function.
