Product Description
IBM EN1B PCIe3 LP 32Gb 2-port Fibre Channel Adapter (CCIN 578F, P/N 01FT704)
The IBM EN1B is the low-profile variant of the high-performance PCIe3 dual-port Fibre Channel host bus adapter (HBA), delivering up to 32 Gb/s per port using SR (Short Range) optics via SFP+ transceivers. Designed specifically for IBM Power Systems servers with low-profile PCIe slots, this adapter supports auto-negotiation down to 16 Gb/s and 8 Gb/s for broad compatibility, ensuring high-throughput, reliable connectivity to storage area networks (SANs) in 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 3.0 x8 low-profile interface for high bandwidth and low latency in space-constrained servers
- 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 depending on fiber type)
- Low-profile form factor (includes low-profile bracket) compatible with PCIe3 slots requiring reduced height
- Compliant with Fibre Channel standards for reliable SAN connectivity
- High-performance Emulex-based design optimized for Power Systems storage workloads
