  • Directory and file mirroring for migration, snapshot, and replication
    Patent number: 7720796
    Abstract: A NAS switch provides mirroring in a NAS storage network that is transparent to client. A source file server exports an original NAS file handles indicative of object locations on the source file server to the NAS switch. The NAS switch modifies the original NAS file handles to an internal file system and maps the original NAS file handles to a switch file handles independent of location. The NAS switch exports the switch file handles to a client. The client looks-up objects and makes NAS requests to the source file server using switch file handles. The NAS switch performs mirroring of a namespace when during processes such as data migration, data replication, and data snapshot.
