    IBM Power9 Expansions - PCIe Gen3/Gen4 I/O & NVMe Drawers

    Discover scalable expansion solutions for IBM Power9 systems. These PCIe Gen3 and Gen4 I/O drawers, fanout modules, NVMe storage expansions, and supporting cables/adapters add PCIe adapter slots and high-speed NVMe bays to support demanding workloads in AIX, IBM i, or Linux environments. Designed for rack-mount flexibility, they connect via appropriate converter cards and cable pairs for enhanced I/O and storage capacity on Power9 servers.

    Why Choose Power9 Expansions?

    IBM Power9 servers (e.g., S922/S924 9009-22A/42A, E950 9040-MRX, E980 9080-M9S) benefit from external expansions to increase PCIe adapter capacity and NVMe storage beyond internal limits. PCIe Gen3 drawers (#EMX0) provide up to 12 PCIe Gen3 slots, while Gen4 options (#ENZ0) offer higher bandwidth for newer adapters. NVMe expansion drawers add high-performance U.2 NVMe bays for enterprise SSDs. These units attach via CXP or other converter cards and cable pairs (optical for extended reach, copper for cost efficiency), providing redundancy and scalability. Ideal for cloud, analytics, AI, and mission-critical applications requiring expanded I/O and storage without full system replacement.

    Available IBM Power9 Expansions & Components

    • IBM EMX0 PCIe Gen3 I/O Expansion Drawer Feature Code: EMX0 4U rack-mount PCIe Gen3 I/O drawer (19-inch wide). Supports up to 12 PCIe Gen3 slots (full-length/full-height) when populated with dual fanout modules. Standard expansion for Power9 servers, connects via appropriate converter cards and cable pairs. Backward compatible with many Power9 configurations.
    • IBM ENZ0 PCIe Gen4 I/O Expansion Drawer Feature Code: ENZ0 4U rack-mount PCIe Gen4 I/O drawer. Supports up to 12 PCIe Gen4 slots (8 x16 & 4 x8) with dual #ENZF fanout modules. Higher-bandwidth upgrade path for Power9 systems supporting Gen4 adapters. Connects via CXP Converter Cards (#EJ24 or #EJ2A) and cable pairs (#ECLX 3m optical, #ECLY 10m optical, #ECLS 3m copper).
    • IBM ENZF PCIe4 6-Slot Fanout Module Feature Code: ENZF PCIe Gen4 fanout module for ENZ0 drawer. Delivers six PCIe Gen4 slots per module (4 x16 & 2 x8 using x16 connectors; full-length/full-height). Dual modules fully populate ENZ0 for 12 slots total. Required for Gen4 expansion on compatible Power9 systems.
    • IBM ESR0 NED24 NVMe Expansion Drawer Feature Code: ESR0 2U rack-mount NVMe storage expansion with 24 U.2 NVMe bays (supports 7mm/15mm Gen3 carriers). Dual redundant AC power supplies. Connects via dual CXP Converter adapters (#EJ24 or #EJ2A) and cable pairs (#ECLX, #ECLY, #ECLS). Supports IBM U.2 NVMe SSDs for high-performance storage on Power9 servers.

    Note: Power9 expansions require matching converter cards and cable pairs for attachment. Gen3 drawers (#EMX0) are widely compatible with Power9; Gen4 (#ENZ0/ENZF) offer higher bandwidth on supported models. Optical cables provide extended reach; copper is cost-effective for shorter distances.

    Compatibility & Support

    These expansions are compatible with IBM Power9-based systems, including but not limited to Power S922 / S924 (9009-22A / 42A), Power E950 (9040-MRX), Power E980 (9080-M9S), other Power9 servers supporting PCIe Gen3/Gen4 I/O and NVMe expansions, and compatible with AIX, IBM i, and Linux environments.

    Refer to individual product pages for exact connection requirements, supported adapters/SSDs, OS/firmware compatibility, and installation notes. All items include a 60-day limited warranty.
