Product Description
IBM EN1J PCIe4 32Gb 2-port Optical Fibre Channel Adapter (CCIN 579C, P/N 02CM909)
The IBM EN1J is a high-performance PCIe4 dual-port Fibre Channel host bus adapter (HBA) delivering up to 32 Gb/s per port using SR (Short Range) optics via SFP+ transceivers. This full-height adapter is designed for IBM Power Systems servers with PCIe Gen4 infrastructure, supporting auto-negotiation down to 16 Gb/s and 8 Gb/s for backward compatibility. It provides ultra-high-throughput, low-latency connectivity to storage area networks (SANs) in modern enterprise environments running AIX, IBM i, Linux, and VIOS.
Features
- Dual SFP+ ports supporting 32 Gb/s Fibre Channel with SR optics (multimode fiber)
- Auto-negotiation for 32/16/8 Gb/s speeds per port
- PCIe 4.0 x8 interface for superior bandwidth and reduced latency compared to PCIe3
- Each port capable of independent 32 Gb/s Fibre Channel throughput
- Support for standard SR transceivers and multimode fiber cabling (typically up to 100 m at 32 Gb/s with OM3/OM4 fiber)
- Short, full-height form factor with bracket for standard PCIe4 slots
- Compliant with Fibre Channel standards for reliable, high-speed SAN connectivity
- Marvell QLE2772-based design optimized for Power Systems storage workloads with advanced features like NPIV support
