Abstract:
An access request including a client address for data is received. A metadata server determines a mapping between the client address and storage unit identifiers for the data. Each of the one or more storage unit identifiers uniquely identifies content of a storage unit and the metadata server stores mappings on storage unit identifiers that are referenced by client addresses. The one or more storage unit identifiers are sent to one or more block servers. The one or more block servers service the request using the one or more storage unit identifiers where the one or more block servers store information on where a storage unit is stored on a block server for a storage unit identifier. Also, multiple client addresses associated with a storage unit with a same storage unit identifier are mapped to a single storage unit stored in a storage medium for a block server.
