Product Description
IBM EC3M PCIe3 2-port 100GbE NIC RoCE Adapter 00WT041
The IBM EC3M 00WT041 is a high-performance dual-port 100 Gigabit Ethernet Network Interface Card based on Mellanox ConnectX-5 technology. This PCIe Gen3 x16 adapter delivers ultra-low latency, high bandwidth, and RDMA over Converged Ethernet (RoCE) support, making it ideal for demanding networking applications in IBM Power Systems environments.
With two QSFP28 ports supporting 100GbE (or 4x25GbE breakout), the EC3M enables high-speed connectivity for cloud, HPC, big data analytics, AI/ML workloads, and storage fabrics. It offloads TCP/IP, RoCE v2, and other protocols to reduce CPU utilization, improve throughput, and minimize latency in virtualized and bare-metal deployments.
Features include advanced congestion control, adaptive routing, hardware-accelerated encryption (IPsec), and full IBM certification for Power Systems running AIX, IBM i, or Linux. The adapter supports direct attach copper (DAC), active optical cables (AOC), and transceivers for flexible cabling options.
The IBM EC3M PCIe3 2-Port 100GbE NIC RoCE Adapter (00WT041) is backed by a 60-day warranty, providing assurance in its quality and operation.
