January 4, 2026 By Waves Off
The IBM 8284-EN0Y refers to the IBM EN0Y PCIe2 Low-Profile 8Gb 4-Port Fibre Channel Adapter, a hardware component (Host Bus Adapter or HBA) for IBM Power Systems, designed for high-speed storage area network (SAN) connections, offering four 8Gbps Fibre Channel ports, typically used in S822 (8284-22A) servers for AIX and Linux environments to connect to storage arrays.
Key Characteristics:
Type: Fibre Channel Host Bus Adapter (HBA).
Speed: Supports 2, 4, and 8 Gbps (Gigabits per second) link speeds.
Ports: Four Fibre Channel ports, using mini-LC connectors for shortwave optics.
Form Factor: Low-Profile (LP), x8 Short Form Factor Plus (SFF+).
Technology: PCIe Generation 2 (PCIe2).
Virtualization: Supports N_Port ID Virtualization (NPIV) for multiple logical connections per port.
Compatibility: Used in IBM Power Systems servers like the 8284-22A (Power System S822).
Operating Systems: Supported on AIX and Linux; IBM i requires VIOS (Virtual I/O Server).
