Description
The NVIDIA Mellanox MCX653106A-HDAT is a ConnectX-6 adapter card that supports both InfiniBand and Ethernet. It offers two QSFP56 ports for HDR 200Gb/s InfiniBand and 200GbE. On the InfiniBand side it supports SDR, DDR, QDR, FDR, EDR, HDR100 and HDR rates. On the Ethernet side it supports 1, 10, 25, 40, 50, 100 and 200Gb/s. The card uses a PCIe x16 edge connector and is compatible with PCIe Gen 3.0 and Gen 4.0. It can deliver up to 200Gb/s in a PCIe Gen 4.0 slot, or up to 100Gb/s in a Gen 3.0 slot.
Built on the MT28908A0-XCCF-HVM adapter IC, this card measures 167.65mm x 68.90mm in a half-height, half-length form factor and ships with a tall bracket. Typical power with passive cables is 23.6W, and each QSFP56 port can supply up to 5W to attached modules. Install the card in a PCIe slot that can supply the required power and airflow.
