    IBM Power5 Expansions - PCI-X Towers, I/O Drawers & Storage Units

    Discover scalable expansion solutions for IBM Power5 systems. These PCI-X towers, I/O drawers, storage expansion units, and disk enclosures add adapter slots, disk bays, and I/O capacity to support growing workloads in AIX, IBM i (i5/OS), or Linux environments. Designed for rack or tower configurations, they connect via SPD, RIO/HSL, or direct attachment for enhanced performance and scalability on Power5 servers.

    Why Choose Power5 Expansions?

    IBM Power5 servers (e.g., p5-520, p5-550, p5-570, p5-575, p5-590, p5-595, System i5 models) benefit from external expansions to increase PCI/PCI-X adapter capacity and storage beyond internal limits. PCI-X towers (5094/5095) provide disk bays and slots, while I/O drawers (5088/5094) and storage units (505x series) add high-capacity disk options. These units attach via RIO/HSL cables or direct connections, offering redundancy and scalability. Ideal for enterprise workloads, virtualization, and databases requiring expanded I/O and storage without full system replacement.

    Available IBM Power5 Expansions & Components

    • IBM 5094 PCI-X Expansion Tower Feature Code: 5094 PCI-X expansion tower with 14 PCI slots and 12 disk bays. Supports Ultra320 SCSI disk units. Provides high-capacity I/O and storage expansion for Power5 and System i5 systems.
    • IBM 5095 PCI-X Expansion Tower Feature Code: 5095 PCI-X tower with 7 PCI slots and 12 disk bays. Compact expansion for mid-range Power5 configurations. Compatible with SPD and RIO attachment.
    • IBM 5088 PCI-X Expansion Drawer Feature Code: 5088 4U rack-mount PCI-X expansion drawer with 14 PCI slots. Adds adapter capacity for Power5 systems via RIO/HSL connection. Ideal for I/O-intensive workloads.
    • IBM 5052 Storage Expansion Unit Feature Code: 5052 Storage expansion with 16 disk slots. Compatible with Power5 models like 550/570. Adds disk capacity for legacy storage needs.
    • IBM 5051 Storage Expansion Unit Feature Code: 5051 8-disk slot expansion unit for Power5 systems. Supports Ultra SCSI disk units for cost-effective storage growth.
    • IBM 5058 Storage Expansion Unit Feature Code: 5058 16-disk slot expansion with battery backup unit. Enhances reliability for storage-intensive Power5 workloads.

    Note: Power5 expansions primarily use PCI-X and SPD technology (5094/5095 towers, 5088 drawers). Storage units (505x series) support Ultra SCSI disks. Always verify exact cable/controller requirements and compatibility for your specific Power5 model.

    Compatibility & Support

    These expansions are compatible with IBM Power5-based systems, including but not limited to p5-520, p5-550, p5-570, p5-575, p5-590, p5-595, System i5 models with Power5 processors, and compatible I/O enclosures, racks, and configurations.

    Refer to individual product pages for exact connection requirements, supported adapters/drives, OS/firmware compatibility (AIX, IBM i/i5/OS, Linux), and installation notes. All items include a 60-day limited warranty.
