  • Configuring VM and IO storage adapter VF for virtual target addressing during direct data access
    Patent number: 9262189
    Abstract: A method is provided for use in a system that includes a host computing machine configured to implement a virtualization intermediary and that includes a physical storage adapter, the configures a virtual machine (VM) and a virtual function (VF) to support IO operations to physical storage through a direct IOV path to the VF of the physical storage adapter, the method comprises: creating by the virtualization intermediary mapping information that includes a first mapping between virtual disks and physical regions of physical storage and that includes a second mapping between virtual disks and virtual disk addresses; transmitting the mapping information from the virtualization intermediary over the physical storage adapter from a physical function (PF) of the physical storage adapter to the VF; associating a virtual port with the mapping information within the virtualization intermediary; binding the virtual port to the VF; communicating virtual disk addresses indicated within the second mapping within the tra

  • Live migration of virtual machine during direct access to storage over SR IOV adapter
    Patent number: 9086904
    Abstract: A method is provided to migrate a virtual machine from a source computing machine to a destination computing machine comprising: suspending transmission of requests from a request queue disposed in source computing machine memory associated with the VM from the request queue to a VF; while suspending the transmission of requests, determining when no more outstanding responses to prior requests remain to be received; in response to a determination that no more outstanding responses to prior requests remain to be received, transferring state information that is indicative of locations of requests inserted to the request queue from the VF to a PF and from the PF to a memory region associated with a virtualization intermediary of the source computing machine.

  • Virtualization intermediary/virtual machine guest operating system collaborative SCSI path management
    Patent number: 8719817
    Abstract: A method of direct access by a virtual machine (VM) running on a host machine to physical storage via a virtual function (VF) running on an input/output (IO) adapter comprising: providing by a virtualization intermediary running on the host machine an indication of an active path associated with a virtual storage device; obtaining by a guest driver running within a guest operating system of the VM the stored indication of the active path from the shared memory region; dispatching an IO request by the guest driver to the VF that includes an indication of the active path; and sending by the VF an IO request that includes the indicated active path.
