2.4 Host Channel Adapters and Firmware
Every node that is part of the high-speed InfiniBand fabric requires a host channel adapter (HCA)
installed in its PCI bus. The HCA is installed in a specific PCI slot on an unshared bus of the
appropriate speed, ensuring system performance. For more information on supported HCA
models, supported drivers, and installation instructions, see
