Switch and HCAs InfiniBand Cable Connectivity Matrix
NVIDIA Quantum™ based switches and NVIDIA® 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 |
FDR | 56Gb/s | 4 lanes of 14Gb/s |
The following tables present the connectivity matrix, between NVIDIA Quantum based switches, ConnectX-6 HCA, and the cables.
