摘要： By incorporating a referral mechanism, a failover method and system for remotely mirrored clustered file servers enables a client computer to transparently access a remotely mirrored file system during a failover of a first NAS (network attached storage) storing the file system. The first NAS is clustered with a second NAS that takes over the IP address of the first NAS on failover. A mirroring relationship is established between the first NAS and a third NAS whereby a copy of the file system is replicated to the third NAS. A referral is created on the second NAS, such that an access attempt from the client computer for accessing the first file system that is directed to the second NAS following IP address takeover from the first NAS after failover is referred to the third NAS by the referral to enable the client computer to access the copy of the file system.

摘要： Described is a long-term data archiving system. The inventive methodology provides a method for legacy applications to access long-term archived data even if the storage system access method has changed. Data from the legacy storage system is migrated to the modern storage system. During the migration, the notations associated with the data storage units within the legacy storage system are converted to the notations of the modern storage system using one or more conversion rules. In this manner, the proper location for the migrated data within the modern storage system is determined. Upon the completion of the migration, the new location of the migrated data is preserved.

摘要： A system and method for object-level snapshot creation in an object-based storage system. The host device includes a first object management table (OMT) and a file system. The object-based storage system is connected to the host device and includes a controller and object-based storage devices (OSD). The controller includes a snapshot module, a second OMT. The snapshot module receives and processes OSD and other commands from the file system or a service processor, creates an original object and a mirror object in an OSD, and initiates a snapshot operation in an OSD. The first OMT may also reside at a metadata server. A snapshot operation may be a mirror operation or a copy on write operation. The first OMT and the second OMT maintain mapping information of a file identifier, a partition ID, and an object ID, and an object status and a generation number of snapshots.

摘要： System and method for restricting the number of times the objects may be copied in an object based storage system. A command is generated by a host device that sets a copy limit for an object at the storage system. An OSD command is generated at the storage system that sets a copy limitation flag attribute and a copy limit attribute of the object. Updating the value of the copy limitation attribute of an object during a copy pair creation operation includes: starting an initial copy of objects from a source LU to a destination LU if neither of the logical units are used for the other copy pair, reading each object in the source LU, decrementing by one a copy limit value of each object, sending each object to a second processor module at a remote site, and writing each object at the second processor module to the destination LU.
