Product Description
IBM EC2U PCIe3 2-Port 25/10Gb NIC&ROCE SR/Cu Adapter
The IBM EC2U PCIe3 2-Port 25/10Gb NIC & RoCE SR/Cu Adapter (CCIN 58FB, part number 01FT753) is a low-profile, dual-port converged network adapter designed for IBM Power Systems servers. This PCIe Gen3 x8 card provides two SFP28 ports supporting 25 GbE and 10 GbE Ethernet (backward compatible with 1 GbE), plus full RoCE (RDMA over Converged Ethernet) v1/v2 support, delivering ultra-low latency, high throughput, and CPU-efficient networking for AIX, IBM i, Linux, and VIOS environments in high-performance computing, virtualization, AI/ML, database clustering, and storage fabrics (iSER, NVMe-oF).
Product Description
The IBM EC2U (feature code EC2U, CCIN 58FB, part number 01FT753) is a low-profile PCIe Gen3 x8 dual-port 25/10 GbE adapter with RoCE support. It occupies a single PCIe Gen3 x8 slot and features two SFP28 ports that auto-negotiate 25 GbE, 10 GbE, and 1 GbE speeds over direct-attach copper (DAC) or fiber optic cabling. The adapter uses Mellanox ConnectX-4 Lx-based technology with advanced offload features including RoCE v1/v2 (RDMA), TCP/UDP/IP checksum offload, large send offload (LSO), receive side scaling (RSS), SR-IOV (up to 127 VFs), and hardware-based flow steering. It supports low-latency RDMA for HPC, storage fabrics (iSER, NVMe-oF), and virtualized environments (PowerVM, VMware). The EC2U is fully qualified for Power9 and Power10 systems requiring high-bandwidth, low-latency networking with RoCE acceleration, making it ideal for modern data center, cloud, AI, and converged storage workloads on AIX, IBM i, Linux, and VIOS.
