摘要: I/O bandwidth reduction using storage-level common page information is implemented by a storage server, in response to receiving request from client for stored at first virtual address, determining that the address maps duplicate of second or and addresses map deduplicated within system, transmitting metadata mapping also page. For one embodiment, transmitted anticipation redundant/deduplicated via address. an alternate sent determination was previously client.
