SYSTEM AND METHOD FOR PROVIDING AN INFINIBAND SR-IOV vSWITCH ARCHITECTURE FOR A HIGH PERFORMANCE CLOUD COMPUTING ENVIRONMENT

A method for supporting virtual machine live migration in a subnet, comprising:

• providing, at one or more computers, including one or more microprocessors,
• one or more switches, the one or more switches comprising at least a leaf switch, wherein each of the one or more switches comprise a plurality of ports,
• a plurality of host channel adapters, wherein each of the host channel adapters comprises at least one virtual function, and wherein the plurality of host channel adapters are interconnected via the one or more switches,
• a plurality of hypervisors, wherein each of the plurality of hypervisors are associated with at least one of the plurality of host channel adapters, and
• a plurality of virtual machines, wherein each of the plurality of virtual machines are associated with at least one virtual function;
• arranging 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;
• and
• live migrating a first virtual machine of the plurality of virtual machines running on a first hypervisor of the plurality of hypervisors to a second hypervisor of the plurality of hypervisors;
• and
• wherein the first hypervisor is associated with a first host channel adapter of the plurality of host channel adapters, and the second hypervisor is associated with a second host channel adapter of the plurality of host channel adapters.

A non-transitory computer readable storage medium, including instructions stored thereon for supporting virtual machine live migration in a subnet which when read and executed by one or more computers cause the one or more computers to perform steps comprising:

• providing, at one or more computers, including one or more microprocessors,
• one or more switches, the one or more switches comprising at least a leaf switch, wherein each of the one or more switches comprise a plurality of ports,
• a plurality of host channel adapters, wherein each of the host channel adapters comprises at least one virtual function, and wherein the plurality of host channel adapters are interconnected via the one or more switches,
• a plurality of hypervisors, wherein each of the plurality of hypervisors are associated with at least one of the plurality of host channel adapters, and
• a plurality of virtual machines, wherein each of the plurality of virtual machines are associated with at least one virtual function;
• arranging 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;
• and
• live migrating a first virtual machine of the plurality of virtual machines running on a first hypervisor of the plurality of hypervisors to a second hypervisor of the plurality of hypervisors;
• and
• wherein the first hypervisor is associated with a first host channel adapter of the plurality of host channel adapters, and the second hypervisor is associated with a second host channel adapter of the plurality of host channel adapters.
