Product Description
IBM EN0B PCIe3 16Gb 2-port Fibre Channel Adapter (CCIN 577F, P/N 00E3496)
The IBM EN0B is a high-performance, dual-port 16 Gb/s Fibre Channel host bus adapter designed for IBM Power Systems servers. This PCIe Gen3 x8 adapter provides two 16 Gb/s FC ports for reliable, low-latency storage connectivity to Fibre Channel SANs, supporting enterprise storage arrays (FlashSystem, DS8000, Storwize/SVC), tape libraries, and NVMe over Fibre Channel (NVMe/FC) in compatible configurations, ideal for AIX, IBM i, Linux, and VIOS environments in mission-critical data centers.
Product Description
The IBM EN0B (feature code EN0B, CCIN 577F, part number 00E3496) is a PCIe Gen3 x8 dual-port 16 Gb/s Fibre Channel adapter that occupies a single PCIe slot on the host server. It features two SFP+ ports supporting auto-sensing speeds of 16 Gb/s, 8 Gb/s, and 4 Gb/s Fibre Channel (backward compatible with older FC infrastructure), delivering up to 32 Gbps aggregate bandwidth across both ports. The adapter uses Emulex-based controllers (typically LPe32002 or similar) with advanced offload features including NPIV (N_Port ID Virtualization), large queue depths, hardware-assisted fabric management, and multipath I/O (MPIO) support. It enables boot-from-SAN, zoning, and full IBM qualification for reliability, power management, and firmware integration. The EN0B is optimized for balanced SAN attachment in Power8, Power9, and Power10 systems, providing cost-effective, high-performance block storage access, virtualization (PowerVM, VMware), and disaster recovery/replication workloads where dual-port redundancy is required.
