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: An architecture 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 switched storage network in the storage area networks the architecture comprising one or more processors in communication with switching capability for the switched storage network, wherein the one or more processors include program logic for embodying logical constructions of a storage presentation layer including target virtualization and logical unit (LU) virtualization; and a volume presentation layer including volume virtualization for replication of data.

Abstract: This invention is a system and method for managing one or more data storage networks using a new architecture. A method for handling logical to physical mapping is included in one embodiment with the new architecture. A method for handling errors is included in another embodiment with the new architecture.

Abstract: In one aspect, a computer-implemented method includes receiving a storage request having a storage pool policy, a volume creation policy, and volume creation attributes; searching available storage in a dynamic storage pool and storage connectivity elements based upon the storage request; selecting front-end and back-end virtual local area networks (VLANs), zones, and virtual initiators (VIs) matching a service level agreement (SLA) for the storage request; determining a provisioning plan for the storage request including an array, array ports, the virtual targets (VTs), the VIs, the zones, the VLANs, virtual volume identity, and logical units by examining resources for the VTs and VIs including resource usage and input/output operations per second to select a VT/VI pair based on the SLA; masking and mapping the virtual volume to the array ports to the VIs; creating a back-end zone for connectivity between the virtual targets and host bus adaptor ports; and outputting the provisioning plan to a user for displ

Abstract: A system and method for managing one or more Storage Area Networks (SAN), in which the one or more SAN's consist of one or more data storage volumes and one or more hosts. Whereas the one or more data storage volumes are in a switched storage network.

Abstract: An architecture for managing a switched storage network consisting of one or more data storage volumes and one or more hosts. The data storage volumes are in a switched storage network. One or more processors provide the switching capability for the switched storage network. The one or more processors are capable of embodying logical constructions of a storage presentation layer and a volume presentation layer.

Abstract: Described is a technique for asynchronous event notification in a data storage system. Lower level software, such as a device driver or other software application generating events, reports the occurrence of an event to an event handler. The event handler implements an event reporting policy which may include event consolidation. The event handler reports the events to an event dispatcher which notifies event subscribers of the occurrence of events in accordance with registration information of each subscriber. The event handler may execute in kernel mode or user mode depending on the particular execution mode of lower level software initially reporting the occurrence of events. There may be a hierarchical arrangement of multiple event dispatchers in connection with event reporting. Event dispatchers may implement data sharing of registration information.
