IBM EJ0M 57B4 PCIe3 RAID SAS quad-port 6 Gb LP Adapter 000MH910
IBM EJ0M PCIe3 RAID SAS quad-port 6 Gb LP Adapter is a PCI Express (PCIe) RAID SAS adapter in a low-profile and short-form factor for IBM i, Power AIX, Linux Server and VIOS partitions. IBM EJ0J and EJ0M are identical RAID adapters, have the same 57B4 CCIN and part number 000MH910. The EJ0J has a full-high tailstock bracket and air baffle, whereas teh EJ0M has a low profile tailstock bracket. In addition, the EJ10 and EJ11 are identical to the EJ0J and EJ0M, but have different feature codes to specify use as a tape or DVD controller instead of a SSD or hard disk drive controller.
The IBM EJ0M RAID SAS adapter is a high performance SSD and HDD controller using PCIe Gen3 x8 technology. The EJ0M supports the attachment of SAS hard disk drives (HDDs) and solid-state devices (SSDs) by using four mini SAS high-density (HD) x4 connectors for physical links to be used in various narrow and wide-port configurations to the attach SAS drives located in the EXP24S, EXP12SX or EXP24SX storage enclosures or 5802, 5803 or EL36 12X PCIe I/O drawers. The EJ0M adapter does not have write cache, so pairing with another PCIe3 RAID SAS Adapter (EJ0J or EJ0M) is optional. Pairing IBM Power RAID SAS adapters provides controller redundancy and improves I/O performance. The EJ0M has no batteries to maintain.
Other RAID SAS adapters to consider include EJ14, EJ0L, EJ0J, EL3B and EL59. The EJ0M is supported on the following IBM Power9, Power8 and Power7 models: 9009-41A, 9009-42A, 9009-22A, 9080-M9S, 9080-MHE, 9080-MME, 9119-MHE, 9119-MME, 9223-22H, 8202-E4D, 8286-41A, 8286-42A, 8284-21A, 8284-22A, 8284-21A, 8202-E4D, 8231-E2C, 8231-E2D, 8205-E6C, 8205-E6D, 8231-E1C, 8231-E1D, 8247-21L
The EJ0M adapter supports a maximum of 48 solid-state devices (SSDs) and a maximum of 96 hard disk drives (HDD), but depends on the drive enclosure attached. Externally attached devices are designed to run at a maximum data rate of 6 Gbps for SAS disk devices. Specific device attachment support rules apply. EJ0M SAS adapter supports the multi-initiator and high availability (dual storage IOA) configurations in AIX, IBM i, and Linux partitions. This adapter enables configuring the SAS drives as dedicated hot-spares with equal or higher capacity.
IBM Power System Configurations:
The EJ0M SAS adapter supports RAID 0, RAID 5, RAID 6 and RAID 10 for AIX and Linux and VIOS. For IBM i, the EJ0M adapter provides RAID 5, RAID 6 and RAID 10. IBM i provides both OS mirroring and data spreading. AIX, Linux and VIOS provide OS mirroring (LVM). The adapter provides both single and dual RAID controller configurations. Dual controller configurations (dual storage IOA) must run RAID. JBOD (512 byte) functionality is supported only in a single controller configuration based on the operating system. Best performance is achieved when multiple RAID sets are configured and optimized under a pair of adapters in a high availability, multi-initiator RAID configuration (dual storage IOA) which allows for an Active-Active mode of operation. Both 5xx and 4k byte sector HDD/SSD are supported for Power and Power9 servers. 5xx byte sector HDD/SSD are supported for earlier generation servers. 5xx and 4k drives cannot be mixed in the same array.
Limitations:
HDD/SSD workloads which are performance sensitive to WRITES should use the EJ14 or EJ0L controller which provides write cache.
HDD and SSD cannot be mixed on the same SAS port, but can be mixed on the same adapter.
5886 3.5-inch SAS Storage 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 or adapter pair is not supported. Note mixing EXP24S or EXP12SX or EXP24SX is supported.
If controlling drives in a 5802/5803/EL36 as a single controller, the EJ0J must be located in that 5802/5803/EL36. If controlling drives in a 5802/5803/EL36 as a pair of controllers, at least one of the SAS adapter pairs must be located in that 5802/ 5803/EL36.
Tape/DVD cannot be mixed with disk/SSD on the same adapter.
Attributes provided: full high PCIe3 four port x8 SAS RAID adapter with no write cache and optional pairing
Attributes required: One PCIe slot per adapter and Mini-SAS HD narrow connector SAS cables such as ECBJ-ECBL, ECBT-ECBV, ECCO-ECC4 or 12Gb cables such as ECDJ, ECDT or ECDU.
