  • System and method for providing access to replicated data
    Patent number: 8103625
    Abstract: A system and method for providing access to replicated data is disclosed. Embodiments of the present invention utilize a remote access file system to provide access to replicated data concurrently with replication. According to one embodiment including unidirectional replication, access to a replicated target volume is provided using a remote access file system to perform reads locally or “directly” and to perform writes indirectly to a replication source volume which are subsequently replicated to the replication target volume. According to another embodiment, bi-directional replication is provided and access to both replication source and replication target volumes are provided locally and subsequently replicated as necessary.
