Product Description
IBM EN0G PCIe2 8Gb 2-Port Fibre Channel Adapter (CCIN 578D, P/N 00WT111)
The IBM EN0G is a reliable, dual-port 8 Gb/s Fibre Channel host bus adapter designed for IBM Power Systems servers. This PCIe Gen2 x8 adapter provides two 8 Gb/s FC ports for cost-effective, low-latency storage connectivity to Fibre Channel SANs, supporting enterprise storage arrays (DS8000, Storwize/SVC, FlashSystem older models), tape libraries, and traditional FC fabrics in AIX, IBM i, Linux, and VIOS environments.
Product Description
The IBM EN0G (feature code EN0G, CCIN 578D, part number 00WT111) is a PCIe Gen2 x8 dual-port 8 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 8 Gb/s, 4 Gb/s, and 2 Gb/s Fibre Channel (backward compatible with older FC infrastructure), delivering up to 16 Gbps aggregate bandwidth across both ports. The adapter uses QLogic-based controllers (typically QLE2562 or equivalent) 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 EN0G is optimized for legacy and mid-range SAN attachment in Power7+, Power8, and select Power9 systems, providing economical, high-performance block storage access, virtualization (PowerVM, VMware), and disaster recovery/replication workloads where dual-port redundancy is preferred over higher-speed 16 Gb/s or 32 Gb/s adapters.
Features

- NPIV support for virtualized environments (PowerVM, VMware)
- Hardware offload for checksum, header splitting, and large send/receive
- Support for boot-from-SAN, multipath I/O (MPIO), and fabric services
- Hot-plug SFP+ transceivers (short-wave/long-wave/multimode/single-mode)
- LED indicators for link/activity and speed per port
- Full IBM driver and firmware support for AIX, IBM i, Linux, VIOS
