Mellanox InfiniBand HCA Overview One of the features of an InfiniBand fabric is that individual components can contain an InfiniBand host channel adapter (HCA) or a mezzanine HCA. The components that contain HCAs are visible and manageable parts of your InfiniBand fabric. The HCA may be an integrated circuit embedded on the circuit board of a component (such as a storage array controller) or it can be a PCI card that is installed in a server. In an HP Cluster Platform configuration, the HCA can be a single-port or dual-port InfiniBand PCI card. These Mellanox HCAs were installed by HP, but it is assumed that you are familiar with the Mellanox HCAs and have the knowledge necessary to maintain and troubleshoot the HCA and mezzanine card technology. This document contains links to the documentation that describe the various Mellanox and HP HCAs. All of the documentation referenced in this document is currently available on the docs.hp.com and Mellanox websites.
