Product Description
IBM EN0H PCIe3 4-port (10Gb FCoE & 1GbE) SR & RJ45 Adapter (CCIN 2B93, P/N 00E3498)
The IBM EN0H is a converged network adapter (CNA) combining 10 Gigabit Fibre Channel over Ethernet (FCoE) and 1 Gigabit Ethernet connectivity in a single PCIe card for IBM Power Systems servers. This PCIe Gen3 x8 low-profile adapter provides two 10 Gb FCoE ports (short-range optical) and two 1 GbE RJ45 copper ports, enabling unified networking and storage fabric convergence for AIX, IBM i, Linux, and VIOS environments in data centers requiring both high-speed SAN (FCoE) and legacy Ethernet connectivity.
Product Description
The IBM EN0H (feature code EN0H, CCIN 2B93, part number 00E3498) is a PCIe Gen3 x8 converged network adapter that occupies a single low-profile PCIe slot on the host server. It features:
- 2 × 10 Gb FCoE ports (SFP+ optical, short-range multimode fiber) for Fibre Channel storage traffic over Ethernet
- 2 × 1 GbE RJ45 ports (copper) for standard Ethernet LAN connectivity
The adapter uses Broadcom-based controllers (typically BCM57840S or equivalent) with hardware offloads for FCoE, TCP/UDP/IP checksum, large send offload (LSO), VLAN tagging (IEEE 802.1Q), jumbo frames (up to 9K), and NPIV (N_Port ID Virtualization) for virtualized storage. It supports converged networking (unified FCoE + Ethernet fabric), reducing cabling complexity and switch ports while maintaining full FC protocol compatibility. The EN0H is fully qualified for Power8, Power9, and select Power10 systems, making it ideal for transitioning legacy 1 GbE networks to 10 Gb FCoE SANs, virtualized environments (PowerVM, VMware), iSCSI offload, and mixed LAN/storage workloads on AIX, IBM i (iSeries/AS/400), Linux, and VIOS platforms.

- LED indicators for link/activity and speed per port
- Hot-plug SFP+ transceivers on FCoE ports
- Full IBM driver and firmware support for AIX, IBM i, Linux, VIOS
