PCIe4 2-port 100 GbE RoCE x16 adapter (FC EC75 and EC76; CCIN 2CFB)
Learn about the specifications and operating system requirements for feature code (FC) EC75 and EC76 adapters.
Overview
FC EC75 is a low-profile adapter, and FC EC76 is a full-height adapter.
The PCIe4 2-port 100 GbE RoCE x16 adapter is a PCI Express (PCIe) generation 4 (Gen4) x16 adapter. The adapter provides two 100 GbE En ConnectX-6 DX QSFP56 ports. The PCIe4 2-port 100 GbE RoCE En ConnectX-6 DX QSFP56 Adapter supports both NIC (Network Interface Controller) and IBTA RoCE standards. RoCE is Remote Direct Memory Access (RDMA) over Converged Ethernet. Using RoCE, the adapter can support significantly greater bandwidth with low latency. It also minimizes the CPU overhead by more efficiently using memory access. This offloads the CPU from I/O networking tasks, improving performance and scalability.

- Cables
-
For 100G, IBM® offers either Direct Attach Copper (DAC) cables up to 2 M or Active Optical Cables (AOC) up to 50 M. QSFP based transceivers are included on each end of these cables. For more information about adapter cabling, see the Cable and transceiver matrix.
- Transceivers
-
IBM qualifies and supports QSFP optical transceiver (FC EB59) to install into the adapter. Customers can also use their own optical cabling and QSFP56 optical transceiver for the other end. This is a 100Gbase-SR4 based active optical transceiver capable up to 100 M through the OM4 cable or 70 M through OM3 cable. Either one or both of the adapter's two QSFP56 ports can be populated. When two ports are filled, both can have copper cables or optical cables. Additionally, one of the cables can be copper and the other can be optical.
