Abstract
I/O bandwidth reduction using storage-level common page information is implemented by a storage server. In response to receiving a request from a client for a page stored at a first virtual address, the storage server determines that the first virtual address maps to a page that is a duplicate of a page stored at a second virtual address. Or the storage server determines that the first and second virtual addresses map to a deduplicated page within a storage system. The storage server then transmits metadata to the client. The metadata maps the first virtual address to a second virtual address that also maps to the deduplicated page.
