IBM 57B4 Quad-Port 6G SAS RAID Controller PCIe3 x8 for Power8 System 01DH504
IBM 57B4 Quad-Port 6G SAS RAID Controller PCIe3 x8 for Power8 System 01DH504
IBM PCIe3 x8 Quad-Port 6Gb SAS RAID Adapter
1. General Product Overview
The IBM 57B4 is an enterprise-class, high-performance PCI Express Generation 3 (PCIe3) Serial Attached SCSI (SAS) RAID controller designed exclusively for IBM Power Systems architectures, primarily optimizing scale-out and enterprise POWER8 configurations. Featuring four external mini-SAS HD ports, this card delivers extreme physical storage density, hardware-accelerated RAID processing, and high-throughput data bandwidth. It is tailored for mission-critical relational databases, dense virtualization consolidation, and large-scale backup array configurations.

3. Connection & Interface Properties
-
External Connectors: 4 x mini-SAS HD (High Density) x4 physical connectors (
SFF-8644standard alignment). -
Total Port Bandwidth: Supports high-density data arrays with multi-lane broad bandwidth pipelines ($4 \times \text{4-lane links}$).
-
Multi-Device Configurations: Capable of attaching to a wide matrix of external SAS enclosures or disk drawers using certified IBM high-density mini-SAS HD cables.
4. Advanced Hardware RAID Capabilities
-
Supported RAID Levels: Implements hardware-level RAID 0, RAID 5, RAID 6, and RAID 10 configurations.
-
OS Dual-Controller Co-existence: Supports high-availability dual-controller write-cache mirroring configurations (Dual-Storage IOA architectures) under supported operating systems to eliminate single points of failure.
-
Dynamic Sector Integrity: Incorporates standard T10 End-to-End Data Protection (EEDP) with 522-byte sector layouts to maintain complete operational block sanity across heavy dynamic write cycles.
5. System Deployment & OS Support
This storage adapter is integrated directly into the PCIe riser expansion channels of mainstream IBM Power Systems nodes:
-
Target Hardware Systems: IBM Power8 Scale-Out Nodes (e.g., S812, S814, S822, S824) and Scale-Up environments using dedicated external drawers like the EXP24S (
FC 5887) or EXP12SX (FC ESLS). -
Operating System Support Matrix: Fully certified across IBM AIX, IBM i, and Linux for Power architectures (Requires target system firmware levels and PTF microcode updates).
