Hypervisor Storage Intercept Method

摘要

Two levels of address masquerading are employed to make a virtual appliance a transparent gateway between a hypervisor and a storage controller. This approach allows a virtual appliance to be inserted or removed from the IP storage path of a hypervisor without disrupting communications. One embodiment of the invention enables a virtual appliance to intercept, manipulate, reprioritize, or otherwise affect IP (Internet Protocol) storage protocols sent or received between a hypervisor and storage controller(s).

主权项

1. A software program for use in a data network, said data network comprising at least one server having a central processing unit executing instructions which create a plurality of virtual machines and a hypervisor, said data network further comprising a storage controller, and a physical network connecting the server and the storage controller, said software program comprising a non-transitory media having instructions, which, when executed by said central processing unit, creates a virtual appliance in an active I/O stream between said hypervisor and said storage controller, said virtual appliance adapted to:
masquerade as a targeted storage controller, causing the virtual appliance to receive storage requests from the hypervisor that would otherwise have been sent directly to the storage controller, and masquerade as the storage interface of the hypervisor to capture responses from the storage controller.
