Abstract
Systems and methods are provided for supporting scalable multi-homed routing for virtual switch based host channel adapter (HCA) virtualization in a subnet. An exemplary method can provide one or more switches, a plurality of host channel adapters, a plurality of hypervisors, and a plurality of virtual machines. The method can arrange the plurality of host channel adapters with one or more of a virtual switch with prepopulated local identifiers (LIDs) architecture or a virtual switch with dynamic LID assignment architecture. The method can further perform a multi-homed routing for the subnet, wherein at least one of the plurality of host channel adapters comprises two virtual switches, wherein the two virtual switches are treated as endpoints of the subnet, and wherein the multi-homed routing for the subnet ensures that each the two virtual switches are routed through independent paths.
