A system and method for operating a storage library. The system comprises a management server, a media agent connected to the management server, a library connected to the media agent and a database connected to the management server. The management server controls the media agent to monitor for the addition or removal of a piece of media in the library. When the media agent determines that the piece of media has been added to the library or removed from the library, the media agent causes the library to read a media label stored as data on the piece of media, the media label including an identifier identifying the piece of media. When a backup or restore is performed, the system checks the media label to ensure that the correct media is being used. Inventory procedures are disclosed. Media labels are stored in a database along with an indication of the corresponding slot where the media is stored, a time when the label was put on the medium, and a confidence parameter indicating how confident the system is that the particular medium is stored in the respective slot.

Remote replication is implemented with hierarchical storage. In exemplary embodiments, a first storage site has a first storage system providing an upper tier of storage and a second storage system providing a lower tier of storage. A remote second storage site has third and fourth storage systems configured to receive remote replication from the first and second storage systems, respectively. When a file is migrated from the upper tier to the lower tier, a stub file is stored in place of the migrated file indicating a storage location of the migrated file on the second storage system. When copies of the migrated file and the stub file are replicated to the fourth and third storage systems, respectively, information is transmitted to the second storage site for linking the copy of the stub file at the third storage system to the copy of the migrated file at the fourth storage system.

In at least one embodiment, in response to introduction of a first storage node into a storage network including a plurality of storage nodes, the first storage node discovers at least one second storage node that is a peer storage node. The first storage node downloads one or more versions of one or more shared soft configurations from the second peer storage node. In response to selection of a first version of a first shared soft configuration for activation, the first storage node subscribes to the first shared soft configuration and activates the first version of the selected shared soft configuration on the first storage node. Thereafter, in response to an update of the first shared soft configuration to a second version on the first storage node, the first storage node propagates the second version of the first shared soft configuration to the second storage node.

The present invention provides a novel coordinated shared storage architecture that permits the amortization of cost of the spares over any number of the storage systems and enables improvements to a number of storage system operations. The coordinated shared storage architecture comprises a plurality of storage systems disk shelves via a plurality of intermediate network devices, such as hubs. Each storage system includes a storage operating system having a target device driver module. The target device driver module permits the storage system to function as a SCSI target and thereby receive and process commands directed to it from other storage systems.

A storage system is configured to create and manage virtual ports on physical ports. The storage system can transfer associations between virtual ports and physical ports when a failure occurs in a physical port or a link connected to the physical port so that a host can access volumes under the virtual ports through another physical port. The storage system can also change associations between virtual ports and physical ports by taking into account the relative loads on the physical ports. When a virtual machine is migrated from one host computer to another, the loads on the physical ports in the storage system can be used to determine whether load balancing should take place. Additionally, the storage system can transfer virtual ports to a remote storage system that will take over the virtual ports, so that a virtual machine can be migrated to remote location.

The system further comprises at least one interposition agent communicatively interposed between the requestor(s) and the data storage device(s) to intercept requests for access from the requestor(s) to the data storage device(s), wherein the interposition agent is operable to selectively determine ones of the intercepted requests to impact and selectively simulate a fault for the selected at least one of the requests.

The present idea provides a high read and write performance from / to a solid state memory device. The main memory of the controller is not blocked by a complete address mapping table covering the entire memory device. Instead such table is stored in the memory device itself, and only selected portions of address mapping information are buffered in the main memory in a read cache and a write cache. A separation of the read cache from the write cache enables an address mapping entry being evictable from the read cache without the need to update the related flash memory page storing such entry in the flash memory device. By this design, the read cache may advantageously be stored on a DRAM even without power down protection, while the write cache may preferably be implemented in nonvolatile or other fail-safe memory. This leads to a reduction of the overall provisioning of nonvolatile or fail-safe memory and to an improved scalability and performance.
