Appendix B. PCIe Gen 4 x16 2-port HDR 100 Gb
InfiniBand ConnectX-6 adapter (FC EC6G; CCIN
590E)
Learn about the specifications and operating system requirements for feature code (FC) EC6G.
Overview
FC EC6G is a low-profile adapter. The PCIe Gen 4 x16 2-port high data rate (HDR) 100 Gb InfiniBand (IB)
ConnectX-6 adapter is a PCI Express (PCIe) generation 4 (Gen 4) x16 adapter. This adapter can be used
in a x16 PCIe slot in the system. The adapter enables higher HPC performance with new Message Passing
Interface (MPI) offloads, such as MPI Tag Matching and MPI AlltoAll operations, advanced dynamic
routing, and new capabilities to perform various data algorithms. The HDR 100 Gb adapter supports
connecting to an HDR 200 Gb switch by using HDR 100 Gb splitter cables such as Direct Attach Copper
(DAC) or Active Optical Cables (AOC). Splitter cables allow a single HDR 200 Gb switch port to connect to
HDR 100 Gb ports, doubling a typical HDR switch capacity from 40 ports to 80 ports. The HDR 100 Gb
adapter also supports enhanced data rate (EDR) copper and optical cables when connecting to EDR 100
Gb or HDR 200 Gb InfiniBand switches. For more information about cables, see the cable matrix table.
Note: The Virtual Protocol Interconnect (VPI) feature is supported on this adapter. The adapter may be
used as an InfiniBand adapter or an Ethernet adapter.
