Method for configuring a physical adapter with virtual function (VF) and physical function (PF) for controlling address translation between virtual disks and physical storage regions |
摘要 |
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 transmitted mapping information for the allocated virtual disks to the VM.
