Product Description
IBM EJ0M PCIe3 RAID SAS Adapter Quad-port 6Gb x8
The IBM EJ0M PCIe3 RAID SAS Adapter Quad-port 6Gb x8 (CCIN 57B4, part number 00MH910) is a high-performance PCIe Gen3 x8 SAS RAID controller designed for IBM Power Systems servers. This quad-port (4 × Mini-SAS HD) adapter delivers 6 Gb/s SAS connectivity, hardware RAID 0/1/5/6/10 support, and is optimized for protected internal and external storage configurations in AIX, IBM i, Linux, and VIOS environments on Power8, Power9, and select Power10 systems.
Product Description
The IBM EJ0M (feature code EJ0M, CCIN 57B4, part number 00MH910) is a PCIe Gen3 x8 SAS RAID adapter with four Mini-SAS HD (SFF-8643) ports supporting up to 48 internal or external SAS/SATA drives (configuration dependent). It provides enterprise-grade RAID protection (0/1/5/6/10), high throughput, and data integrity for boot, database, ERP, virtualization, and large-scale storage workloads. The adapter features advanced data protection including T10 DIF/DIX, end-to-end CRC, and is backward compatible with 3 Gb/s SAS/SATA devices. It is fully qualified for Power8 (8286 series), Power9 (9009 series), and select Power10 models with compatible PCIe slots and SAS backplanes or external drawers (EXP24S #5887, EXP24SX #ESLS). The EJ0J is a reliable, high-port-count RAID solution for demanding enterprise storage needs on AIX, IBM i (iSeries/AS/400), Linux, and VIOS platforms.
