Virtual host bus adapter and method

摘要

A virtualized storage adapter architecture and method is provided wherein lower level details of the storage adapter architecture are isolated from an operating system and its applications that execute on a virtualization architecture. This isolation may be performed, for example, by providing a virtual storage adapter that is backed by one or more physical storage adapters. The virtual storage adapter may be referenced by a globally unique identifier. For example, the virtual storage adapter may be referenced by a World Wide Node Name (WWNN). In another example, changes may be made to the underlying physical storage configuration without the need for changes in the virtual storage adapter or its interface to an operating system or its applications.
