A system and method for exposing volumes with underlying read-write mediums to user operations. When a medium is in the process of being migrated to a storage array, a volume which relies on the medium can be exposed to user operations (e.g., snapshots, read and write operations) once the portions of the medium which underlie the volume have been migrated. The volume can be exposed to user operations while one or more other portions of the medium are unfilled and while the medium is in an intermediate read-write state.

Systems, methods, and computer readable storage mediums for maintaining the history of remapped data in a storage system. A first portion of a first medium may be remapped to a second medium as part of read optimization operations, wherein the second medium is younger than the first medium. A tag associated with the first portion of the first medium may be retained when the first portion is remapped to the second medium. When the second medium is replicated to another storage array, the first portion of the first medium may be prevented from being replicated based on the tag identifying the first portion as being part of a previous replication operation.

A system and method for utilizing unmapped and unknown states in a storage system. When a first portion of a first medium is determined to be unreachable from any other mediums, the first portion of the first medium may be put into an unmapped state, and its data may be discarded and the corresponding storage locations may be freed. During replication of the first medium to a replica storage array, the state of the first portion of the first medium may be translated from the unmapped state into an unknown state on the replica storage array. If another storage array has the data of the first portion of the first medium, this data may be used to overwrite the first portion of the first medium on the replica storage array, converting the first portion of the first medium from the unknown state into the mapped state.

G06F 3/06

A system and method for performing replication using mediums. A snapshot ‘S’ is selected for replication, and the anchor medium ‘M’ of S is identified. The replica storage array ‘R’ to which M is being replicated determines a list of medium extents which are available. R sends this list to an original storage array ‘O’ and O generates a list of medium extents which need to be sent to R. Only those medium extents corresponding to M which R does not already have will be sent from O to R. Also, R can obtain medium extents from other source storage arrays during the replication process.
