The PCIe3 12 GB Cache RAID SAS Adapter gives HDD and/or SSD controller function using PCIe-3 technology. A set of two adapters are needed in order to provide mirrored write cache data and adapter redundancy. Internal flash memory provides protection of the write cache, without the need for batteries, in case of power loss. Up to 12 GB of write cache is available using compression technology of 4 GB of physical cache.

This adaptor has four Mini-SAS HD connectors for the attachment of SAS drives in the SAS EXP24S or EXP12SX or EXP24SX storage enclosures or #5802/5803/EL36 12X PCIe I/O drawers. X, YO or AT SAS cables with HD narrow connectors are needed to attach to these drawers. A maximum of 4 EXP24S/EXP12SX/EXP24SX can be connected with a max of 96 HDD or 48 SSD. Two AA SAS cable with HD narrow connectors areconnected to the #EJ0L pair to communicate status and cache content information and are required unless three or four ports are being used to attach HDD/SSD.

The #EJ0L provides RAID 0, RAID 5, RAID 6 and RAID 10 for AIX and Linux and VIOS. The adapter provides RAID 5 and RAID 6 for all levels of IBM i and also provides RAID 10 for later levels of IBM i. IBM i provides both OS mirroring and data spreading. AIX/Linux/VIOS provide OS mirroring (LVM). This adapter can also support the Easy Tier function (RAID 52T, 62T or 102T) for AIX and Linux. The adapter's CCIN is 57CE.

Both 5xx and 4k byte sector HDD/SSD are supported for POWER8 servers. 5xx byte sector HDD/SSD are supported for earlier generation servers. 5xx and 4k drives cannot be mixed in the same array.
