Abstract: Methods and apparatus for migrating data with minimal disruption in a storage virtualization system. In one embodiment, a method includes collecting information on a backend logical unit (LUN) having a direct path from a host, presenting the backend LUN to the host through a virtual target via the storage virtualization application, disconnecting the direct path from the host to the backend LUN so that the backend LUN is accessed by the host via the storage virtualization application transparently to the host, and migrating data from the backend LUN to a destination storage transparently to the host.

Abstract: A method and system for managing allocation of storage resources, comprises the steps of: the storage network management system allocating one or more virtual data storage volumes for use by a host computer; the storage network management system presenting the virtual data storage volumes to the host computer as representative of available physical storage on the one or more storage arrays, but not allocating physical data storage for the virtual data storage volumes, wherein the virtual data storage volumes can include regions that are either allocated to physical storage or are unallocated to physical storage; the storage management system creating a data storage pool that includes the one and the more data storage arrays; and upon receiving a write request to the virtual data volume that covers an unallocated region of the volume, the storage network management system allocating physical storage from the storage pool for the virtual data volume.

Abstract: An architecture for protecting against failure in a switched storage network using virtualization.

Abstract: A method, system, and program product for managing a plurality of storage area networks including a plurality of data storage volumes and one or more hosts, wherein the volumes are in a storage network, wherein the network includes one or more processors in the network, the program product comprising a computer-readable storage medium encoded with computer-executable program code enabling controlling virtualization of volumes in the storage network and managing a SCSI virtualization service; wherein the volume virtualization controller service supports virtualization enabling virtual Storage Area Networks (SAN)s by parsing between front-end SANs and back-end SANs regardless of physical configuration of the front and back-end SANs, to enable mapping from virtual volumes to back-end storage elements across virtual SANs.

Abstract: Technology for minimizing disruptions when host data on a physical volume is encapsulated into a virtualization layer or de-encapsulated is disclosed. Evaluation of a physical volume used as data storage for a virtualization layer before committing to direct access to the physical volume is enabled by preventing direct access before presenting the physical volume directly to the host and by preventing the virtualization layer from moving data on the physical volume while redirecting to the physical volume a first plurality of I/O requests that were directed to the virtualization layer.

Abstract: This invention is a system and method for managing provisioning of resources for one or more data storage networks using a new architecture.

Abstract: Methods and apparatus for a storage virtualization system with distributed event processing. In an exemplary embodiment, a method comprises receiving an event by an intelligent switch in a storage virtualization system in which the intelligent switch is coupled to a control path cluster, identifying a type of the event to determine whether the event can be processed by the intelligent switch, processing the event by the intelligent switch where the event type is of a type that can be processed by the intelligent switch, wherein the intelligent switch continues to run in the absence of the control path cluster without direct communication between data path controllers, and processing the event at a control path cluster if the event type cannot be processed by the intelligent switch.

Abstract: This invention is a system and method for managing allocation of storage resources in a storage network, the storage network including physical data storage on a plurality of storage arrays that are in the storage network, and the network is in communication with one or more hosts and the network further includes a storage network management system, communicatively coupled to the storage arrays via the network, the storage management system includes a storage virtualizer capable of intercepting and virtualizing an IO stream from the one or more hosts and which storage network management system further includes a storage and switch controller in communication with the storage virtualizer for storage network management.

Abstract: Systems and methods are provided for executing a vendor specific command in a storage area network including a plurality of data storage volumes and at least one host. In one embodiment, a system includes an intelligent multi-protocol switch (IMPS) and a storage and switch controller that is coupled to the IMPS. The IMPS receives a command from the at least one host. The command includes a command byte field storing a vendor specific service action. The storage and switch controller receives the command from the IMPS. A processor included in the storage and switch controller interprets the vendor specific service action and executes the command.
