With Mellanox CX-4 chipset, the 100G NIC supporting IBTA RDMA and RoCE delivers low-latency and high performance over Band and Ethernet networks. Leveraging DCB capabilities as well as CX4 advanced congestion control hardware mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3 networks.
Ethernet: 100GbE/ 50GbE / 40GbE / 25GbE / 10GbE / 1GbE.
EDR IB: SDR/DDR/QDR/FDR/EDR, each lane of a 4X port runs a bit rate of 25.78125G b/s with a 64b/66b encoding, resulting in an effective bandwidth of 100Gb/s. Single-port QSFP28. Connected with 10, 25, 40, 50 and 100Gb/s Direct Attach Copper cables (DACs), Copper Splitter cables, Active Optical Cables (AOCs) and Transceivers.
PCI Express Connectors: PCIe Gen 3.0 ( 8.0GT /s) x16.
