Claim Text:
1. A first virtual tape library comprising: a local, non-tape based storage for emulating tape storage elements; a store to store a data structure which associates a first subset of emulated tape storage elements of an emulated tape library with the storage elements in the first virtual tape library and which associates a second subset of emulated tape storage elements of the emulated tape library with corresponding storage elements emulated by remote storage in a second virtual tape library that is separate from the first virtual tape library, wherein the first virtual tape library is to present the emulated tape library that includes the storage elements of the first and second virtual tape libraries to a requesting entity that is separate from the first and second virtual tape libraries and that is configured to interact with a tape library having a target geometry, where the emulated tape library has a geometry that conforms to the target geometry even though the second virtual tape library has a geometry that does not conform to the target geometry; and at least one interface to receive, from the requesting entity, first tape library commands identifying emulated tape storage elements associated with the first virtual tape library, and second tape library commands identifying emulated tape storage elements associated with the second virtual tape library.
