IBM EJ0J PCIe3 RAID SAS Quad Port 6GB Adapter x8 57B4 00E7167 00MH913 000FX846
The IBM EJ0J PCIe3 RAID SAS quad-port 6 Gb Adapter is a PCI Express (PCIe), generation 3 RAID SAS adapter that has a low-profile, short-form factor, but packaged for full height installation. The EJ0J adapter is used in high-performance and high-density, serial attached SCSI (SAS) applications. The EJ0J PCIe3 RAID SAS Adapter is a high performance Enterprise SSD and HDD controller using PCIe Gen3 x8 technology. The EJ0J adapter does not have write cache and thus pairing with another PCIe3 RAID SAS Adapter (EJ0J or EJ0M) is optional. Pairing EJ0J adapters can provide controller redundancy and enhance performance. The EJ0J adapter provides four Mini-SAS HD (high density) narrow connectors for the attachment of SAS drives located in the EXP24S, EXP12SX, or EXP24SX storage enclosures or 5802, 5803 and EL36 12X 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. A maximum of 48 SSD can be attached and a maximum of 96 HDD can be attached per adapter or per adapter pair. The EJ0J has no batteries to maintain.
IBM Power9, Power8 and Power7 systems supported: 9009-41A, 9009-42A, 9009-22A, 9008-22L, 9223-22H, 9223-42H, 8286-41A, 8286-42A, 8284-21A, 8284-22A, 8284-21A, 8284-22A, 8408-44E, 8408-E8E, 8202-E4D, 8231-E2C, 8231-E2D, 8205-E6C, 8205-E6D, 8231-E1C, 8231-E1D, 8247-21L, 8247-22L, 8247-42L, 8284-22A, 8286-41A, 8286-42A, 8408-44E, 8408-E8D, 8408-E8E, 9080-MHE, 9080-MME, 9109-RMD, 9117-MMC, 9117-MMD, 9119-FHB, 9119-MHE, 9119-MME, 9179-MHC, 9179-MHD
The EJ0J supports the attachment of SAS disk and SAS tape by using four mini SAS high-density (HD) x4 connectors that allow the physical links to be used in various narrow and wide-port configurations. SAS tape attachment is only supported in a single adapter configuration and cannot be mixed with SAS disk on the same adapter. The IBM EJ0J adapter does not have write cache. The IBM EJ0J and EJ0M are electronically identical with the same 57B4 CCIN and 00E7167 00MH913 000FX846 part numbers. EJ0J has a full-high tailstock bracket and air baffle and the EJ0M has a low profile tailstock bracket. IBM EJ10 and EJ11 are identical with EJ0J and EJ0M, but have different feature codes to identify their use as tape/DVD controllers to IBM configurator tools instead of disk/SSD controllers.
The EJ0J adapter 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 and VIOS provide OS mirroring (LVM). Both 5xx and 4k byte sector SSD and HDD are supported for Power9 and Power8 servers. 5xx byte sector HDD/SSD are supported for earlier generation servers. 5xx and 4k drives cannot be mixed in the same array. 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.
The EJ0J adapter supports a maximum of 98 attached disk devices that depends on the drive enclosure attached. A maximum of 48 devices can be solid-state devices (SSDs). Externally attached devices are designed to run at a maximum data rate of 6 Gbps for SAS disk devices and 3 Gbps for SAS tape devices. This adapter supports RAID and non-RAID DASD, and SAS tape devices. Specific device attachment support rules apply. This adapter supports the multi-initiator and high availability (dual storage IOA) configurations in AIX, IBM i and Linux partitions. The EJ0J adapter enables configuring the SAS drives as dedicated hot-spares with equal or higher capacity.
- WRITE intesive workloads sensitive to performance should use the EJ14 or EJ0L controller which provides necessary 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 and 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 and EL36 as a single controller, the EJ0J must be located in that 5802, 5803 and EL36. If controlling drives in a 5802, 5803 and EL36 as a pair of controllers, at least one of the SAS adapter pairs must be located in that 5802, 5803 and EL36.
- Tape/DVD cannot be mixed with disk/SSD on the same adapter.
