Switch and HCAs InfiniBand Cable Connectivity Matrix

Mellanox Quantum™ based switches and ConnectX®-6 HCAs support HDR (PAM4, 50Gb/s per lane) and EDR (NRZ, 25Gb/s per lane) technologies. As the ConnectX adapter cards are identified by their maximum supported throughput (e.g. ConnectX-6 VPI 100Gb/s card can support either 2-lanes of 50Gb/s or 4-lanes of 25Gb/s), the exact connectivity will be determined by the cable that is being used.

As a reference:

Speed Mode

Speed Supported

Number of Lanes Used

HDR

200Gb/s InfiniBand

4 lanes of 50Gb/s

HDR100

100Gb/s InfiniBand

2 lanes of 50Gb/s

EDR

100Gb/s InfiniBand

4 lanes of 25Gb/s
