Switch and HCAs InfiniBand Cable Connectivity Matrix
NVIDIA Quantum™ based switches and NVIDIA® ConnectX® 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 |
NDR |
400Gb/s InfiniBand |
4 lanes of 100Gb/s |
NDR200 |
200Gb/s InfiniBand |
2 lanes of 100Gb/s |
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 |
The following tables present the connectivity matrix, between NVIDIA Quantum based switches, ConnectX HCA, and the cables.
Switch-to-Switch Connectivity
NVIDIA Quantum-2 switches come with OSFP cages. NVIDIA Quantum and Switch-IB 2 switches come with QSFP cages. The connectivity matrix below are separated into multiple tables due to the above physical differences between the switches.
