IBM 00MH998 PCIe3 x8 SAS RAID Internal Adapter / Storage Controller 57D7/EJ0S

Core Overview

• Manufacturer: IBM

• Product Type: PCIe Gen3 x8 SAS RAID Internal Storage Controller

• FRU Part Number: 00MH997

• CCIN (Customer Card Identification Number): 57D7

• IBM Feature Codes (FC): * EJ0N: Base internal SAS adapter configuration.

  • EJ0T: Extended or bundled enablement configurations.

• Associated Component Part Number: 00MH997

Architecture & Performance Specifications

• Bus Interface: PCI Express 3.0 (PCIe Gen3) x8 electrical and mechanical interface.

• Controller Processor: High-performance LSI/Broadcom SAS ROC (RAID-on-Chip) architecture.

• Link Speed: Supports up to 6 Gb/s SAS data transfer rates per lane (backward compatible with 3 Gb/s SAS/SATA).

• Port Configuration: Quad-port internal design, connecting directly via proprietary internal high-density mini-SAS cables to the server’s disk drive backplane.

• Cache Architecture: Includes high-speed non-volatile write cache. Flash-backed memory protection ensures data integrity during sudden power loss without requiring a physical Li-Ion battery pack.

RAID & Storage Management

• RAID Levels Supported: RAID 0, RAID 5, RAID 6, and RAID 10.

• JBOD Mode: Supports Just a Bunch of Disks (JBOD) pass-through mode for operating systems or filesystems handling soft-RAID (e.g., ZFS, Linux MDRAID).

• Max Drive Support: Designed to handle up to 12 or 18 small form factor (SFF) SAS HDDs or enterprise SSDs, depending on the specific split-backplane or expanded system configuration.

• Features: Dynamic sector repair, hot-spare drive allocation, background consistency checking, and online capacity expansion (OCE).

Hardware Compatibility

This internal storage card is engineered exclusively for IBM Power Systems (POWER8 Architecture) scale-out enterprise servers. It installs into a dedicated internal PCIe slot near the storage cage rather than standard rear-facing PCIe slots.

Supported server models include:

• IBM Power System S814: Machine Type-Model (MTM) 8286-41A

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

• IBM Power System S824: Machine Type-Model (MTM) 8286-42A

• IBM Power System S822L: Machine Type-Model (MTM) 8247-22L

• IBM Power System S824L: Machine Type-Model (MTM) 8247-42L

Operating System Requirements

To fully leverage the hardware RAID capability of the CCIN 57D7 adapter, the following minimum software versions are required:
