Core Overview

Manufacturer: IBM
Product Type: PCIe Gen3 x8 SAS RAID Internal Storage Controller
FRU Part Number: 00MH906
CCIN (Customer Card Identification Number): 57D7
IBM Feature Code (FC): EJ0V (Typically deployed for configurations interfacing with EJ0T high-function backplanes).
Interchangeable/Compatible FRU Family: 00MH907, 00MH997, 00MH962, 00MH908, 01LK399

Architecture & Performance Specifications

Bus Interface: PCI Express 3.0 (PCIe Gen3) x8 electrical signaling. It docks into specialized internal mainline board storage controller sockets.
Link/Data Transfer Rate: Up to 6 Gb/s SAS bandwidth per lane (fully backward compatible with older generation 3 Gb/s SAS/SATA hardware arrays).
Port Configuration: Dual high-density internal mini-SAS HD port connectors. It attaches via custom internal high-density cables directly to the server’s drive cages.
Cache Architecture: Cacheless variant / No Non-Volatile Flash Write Cache onboard. * Operational Insight: Like its sibling part number 00MH906, when utilized in Linux enterprise environments with the iprutils toolkit running package version 2.4.10 or later, it can allocate up to 1 GB of volatile main system memory as a high-speed write caching tier.

RAID & Storage Management

RAID Levels Supported: Hardware RAID 0, RAID 5, RAID 6, and RAID 10.
JBOD Mode: Supported (Just a Bunch of Disks) pass-through mode, mapping physical paths natively to the underlying operating system file system layout.
Drive Form Factor Compatibility: Optimally handles 2.5-inch Small Form Factor (SFF-3) enterprise hard drives (HDDs) or highly durable enterprise SAS/SATA Solid State Drives (SSDs).
Chassis Deployment Architecture: * Designed to support standard single-adapter backplane arrays routing up to 8 or 12 drives seamlessly.
- Can be installed as part of a redundant or load-balanced pair when configuring dual split-storage backplane environments within enterprise racks.

Hardware Compatibility

The 00MH907 module is engineered exclusively to slide into the proprietary internal storage expansion channels of IBM Power Systems (POWER8 scale-out servers).

Supported system configurations:

IBM Power System S822: Machine Type-Model (MTM) 8284-22A
IBM Power System S821: Machine Type-Model (MTM) 8284-21A

Operating System Requirements

- AIX 6.1 with Technology Level 9 Service Pack 2 (or newer)
IBM i: Supported depending on licensed internal code extensions paired with feature codes.
Linux: Supported via enterprise kernel module branches:
- Red Hat Enterprise Linux (RHEL) 7.0 or newer
- SUSE Linux Enterprise Server (SLES) 11 SP3 or newer
- Ubuntu Server 14.04.3, 16.04, or newer
