Abstract:
An apparatus, system, and method are disclosed for storage write caching. A storage address translation table is used to overlay a user image and a common image. A storage driver stack module receives a storage access call and generates a storage access request with a requested file path and a requested storage address. A storage mapper module receives the storage access request, accesses the storage address translation table, and looks up a matching entry in the storage address translation table where the requested file path matches a saved file path and the requested storage address matches a saved common storage address, and maps a saved user storage address from the matching entry if a match exists.
