IBM EJ0L PCIe3 12GB Cache RAID SAS Adapter Quad-port 6Gb x8 57CE
The IBM EJ0L PCIe3 12GB Cache RAID SAS Adapter provides high performance IBM Enterprise SSD and HDD controller features using PCIe Gen3 technology, and recommended by IBM for WRITE intensive workloads to get the required write cache performance or a EJ14 PCIe3 12GB Cache RAID PLUS SAS Adapter. A pair of EJ0L adapters are required to provide mirrored write cache data and adapter redundancy. Integrated flash memory provides protection of the write cache without batteries in case of power failure. The EJ0L provides up to 12GB of write cache using compression of 4GB of physical cache. The IBM EJ0L PCIe3 12GB Cache RAID SAS Adapter is supported on all Power9, Power8 and Power7 system models, has 57CE CCIN and 00FX840, 00WV514, 00WV516, 00MA051 part numbers.
The IBM EJ0L PCI Express (PCIe) generation 3, 12 GB Cache RAID SAS quad-port 6 Gb Adapter is a large cache PCIe3 SAS adapter that provides high-performance capabilities and supports the attachment of serial-attached SCSI (SAS) disks and SAS solid-state drives (SSDs) through four mini SAS high-density (HD) connectors. The EJ0L has up to a 12 GB write-cache via compression. The adapter is a 64 bit, 3.3 V, bootable SAS adapter that supports RAID levels 0, 5, 6, 10, 5T2, 6T2, and 10T2 as well as system level mirroring via the operating system.
The IBM EJ0L adapter provides four Mini-SAS HD (high density) narrow connectors for the attachment of SAS drives located in the SAS I/O drawer EXP24S, EXP12SX, EXP24SX, 5802, 5803 and EL36 PCIe I/O drawers. X, YO or AT SAS cables with HD narrow connectors are used to attach to these drawers. A max of 4 EXP24S, EXP12SX and EXP24SX can be attached with a maximum of 96 HDD or a maximum of 48 SSD. Two AA SAS cable with HD narrow connectors are attached to the EJ0L pair to communicate status and cache content information and are required unless three or four ports are being used to attach SSD or HDD.
The EJ0L provides RAID 0, RAID 5, RAID 6 and RAID 10 for AIX, 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 and 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 57CE CCIN and 00FX840 part number.
Both 5xx and 4k byte sector SSD and HDD 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. Mixing EXP24S, EXP12SX or EXP24SX is supported.
- HDD and SSD cannot be mixed on the same SAS port, but can be mixed on the same adapter.
- 5886 3.5-inch SAS I/O Drawer is not supported.
- 177GB SSD are not supported.
- Running SAS bays for both a 5887 EXP24S I/O drawer and a 12X-attached 5802/5803 I/O drawer on the same adapter pair is not supported.
- If controlling drives in a 5802, 5803 or EL36 at least one of the EJ0L pairs must be located in that 5802, 5803 or EL36
