Abstract

Systems and methods for application of virtual host channel adapter configuration policies. An exemplary embodiment can provide a host channel adapter (HCA) with a control circuit and a memory, and at least one port operative to connect the HCA to a network fabric. A software driver of the HCA can provide a control API that exposes functionality to hyper-privileged software executing on the host. The hyper privileged software, through the control API, can request registration of a virtual HCA (vHCA) with a virtual function of the HCA. The HCA can forward the registration request to a subnet manger, which can retrieve configuration policies from a cache and return the policies to the HCA for implementation with the virtual function of the HCA.
