    • Power 9 AIX

    Disk for Power9 AIX

    The IBM Power9 AIX Disk Drives category includes enterprise-grade SAS HDDs (10K/15K RPM), SAS SSDs (eMLC/MLC classes), and PCIe-attached NVMe SSDs (Gen3 x8 adapters or limited M.2/U.2 in specific configurations) optimized for AIX workloads on Power9 servers. Power9 systems (e.g., S922, S914, S924, E950, E980) support internal SFF-3 bays (typically 12–18) with SAS HDD/SSD via integrated RAID controllers, plus optional PCIe NVMe adapters (#EC5x series) for flash performance. Capacities range from 300 GB (HDD) to 6.4 TB (NVMe/SSD), with hot-swap carriers, RAID support, and full AIX compatibility (7.1 TL5+, 7.2 TL3+ for NVMe).

    Product Description

    IBM Power9 AIX Disk Drives deliver flexible, high-availability internal storage for AIX environments on Power9 servers, balancing performance, capacity, and reliability. SAS HDDs (SFF-3, 12 Gb/s) provide proven 10K/15K RPM for transactional, database, and mixed workloads, while SAS SSDs offer dramatically higher IOPS and lower latency for virtualization, analytics, and ERP applications. Power9 introduced PCIe-attached NVMe (via x8 adapters like #EC5G/#EC5B series) and limited M.2/U.2 NVMe (in S922/S924 configurations), enabling sub-100 μs latency and significantly higher throughput for flash-optimized AIX apps. Drives use feature codes (e.g., #ESxx for SSDs, #59xx/#ESxx for HDDs) with sector formats supporting AIX (512e/4Kn). Power9 supports internal SAS bays (via backplanes like #EJ1x) and external EXP24SX drawers; NVMe requires specific adapters and AIX levels (7.2 TL3+). All drives are IBM-qualified for endurance, power-loss protection, and integration with AIX mirroring, RAID (via integrated or VIOS), and PowerVM virtualization.

    Features

    • SAS HDDs: 10K/15K RPM for high-throughput random I/O, capacities from 300 GB to 1.8 TB+, RAID 0/1/5/6/10 support.
    • SAS SSDs: Enterprise eMLC/MLC variants, high endurance (1–10 DWPD), capacities from 387 GB to 3.84 TB+, read-intensive or mixed-use classes.
    • NVMe SSDs: PCIe Gen3 x8 adapters (#EC5x series), capacities 800 GB–6.4 TB, ultra-low latency, high IOPS (PCIe card or M.2/U.2 in select models).
    • Form factors: 2.5-inch SFF-3 (primary), limited 3.5-inch LFF via external drawers.
    • Hot-plug carriers, encryption options (select SSDs), and AIX-optimized sector formats.
    • Expansion: EXP24SX (#5887) for additional SAS bays; NVMe via PCIe adapters.

    Technical Specifications

    Specifications vary by feature code and Power9 model (e.g., S922/S924, E950/E980). Common types:

     

    • Latency: SAS SSD ~100–200 μs; NVMe sub-100 μs.
    • IOPS: SAS SSD hundreds of thousands; NVMe millions system-wide.
    • Sector Formats: 512e/4Kn for AIX native.

    Compatibility

    IBM Power9 AIX Disk Drives are qualified for:

    • Power9 Models: S922 (9009-22A/22G), S914 (9009-41A), S924 (9009-42A), E950/E980, and related scale-out/enterprise servers.
    • Operating Systems: AIX 7.1 TL5+ / 7.2 TL3+ (NVMe support), VIOS, Linux (RHEL/SUSE/Ubuntu).
    • Attachment: SAS via integrated backplanes (#EJ1x); NVMe via PCIe adapters (#EC5G/#EC5B series) or M.2/U.2 (select configs).
    • Adapters/Controllers: Integrated SAS RAID; PCIe NVMe adapters for flash.
    • Expansion: EXP24SX (24 SFF bays SAS); NVMe via PCIe adapters.
    • Legacy SAS: Fully supported internally; NVMe requires specific AIX levels and adapters.

    Verify exact feature codes, CCINs, firmware, and backplane options via IBM Sales Manual or resources for your Power9 model.
