摘要： Described is a storage system and method for managing and optimizing power consumption in a storage system. Logical devices are mapped to physical disk drives. A plurality of power profiles is defined. Each power profile is associated with a mode of operation for a physical disk drive. One of the power profiles is assigned to each logical device. One of the physical disk drives is identified for which every logical device mapped to that physical disk drive has been assigned the same power profile. The identified physical disk drive is operated in the mode of operation associated with said same power profile. The mapping of the logical devices to the physical disk drives may be changed in order to group logical devices assigned the same power profile onto the same physical disk drive.

摘要： Described is a storage system and method for reducing power consumption in a storage system by shortening seek distances associated with input/output (I/O) requests to a physical disk drive. A sweep direction is set. An offset of a new I/O request is evaluated to determine whether to send the new I/O request to the physical disk drive. The new I/O request is sent to the physical disk drive if the offset is consistent with the sweep direction. Otherwise, sending the new I/O request to the disk drive is deferred until the sweep direction is set to a reverse direction.

摘要： Described are a storage network and method of migrating data from a source virtual array to a destination virtual array transparently with respect to a storage application executing on a host. The storage application provides particular storage functionality at a source storage array while using metadata during its execution. The metadata used by the storage application are associated with the source virtual array and forwarded, during a data migration event in which data resident in logical units of storage (LUNs) of the source virtual array are copied to LUNs of the destination virtual array, to a destination storage array where the metadata is associated with the destination virtual array.

摘要： Failover is provided from a primary Fiber Channel device to a secondary Fiber Channel device. Source and secondary Fiber Channel devices are coupled to a Fiber Channel fabric having a database that associates Fiber Channel names and Fiber Channel addresses of Fiber Channel ports coupled to it. All data is copied from the primary Fiber Channel device to the secondary Fiber Channel device. In response to a failure, secondary port names and LUN names are replaced with the primary port names and LUN names, and the fabric updates its database so that the database associates the secondary port and LUN addresses with the primary port and LUN names. The secondary Fiber Channel device thereby assumes the primary Fiber Channel device's identity.

摘要： Described are systems and methods of migrating data from a source virtual array to a destination virtual array transparently with respect to a management application program executing on a host and using management information to send management messages to the virtual arrays. Data from the source virtual array are copied to the destination virtual array during a data migration event. First and second virtual array management interfaces are associated with the source and destination virtual arrays, respectively. The first and second virtual array management interfaces are exchanged during the data migration event so that the virtual array management interface associated with the destination virtual array becomes associated with the source virtual array and the virtual array management interface associated with the source virtual array becomes associated with the destination virtual array.

摘要： Described are a storage network and method of presenting a virtual array in the storage network. The storage network includes a first storage array and a second storage array. At least one of the first and second storage arrays has one or more logical units of storage assigned to a virtual array that spans the first and second storage arrays. In addition, at least one of the first and second storage arrays has one or more physical ports coupled to the virtual array. The virtual array is assigned a unique virtual port identifier (ID) for each physical port coupled to the virtual array. A host coupled to a switch can communicate with the virtual array using a virtual port ID assigned to the virtual array.

摘要： A disk drive apparatus has a magnetic platter, a disk drive motor, and a disk drive controller. The disk drive controller is capable of storing data onto and retrieving data from the magnetic platter while the magnetic platter turns at a predefined maximum speed. The disk drive controller is configured to receive a command to access a storage location on the magnetic platter from an external storage controller, and direct the disk drive motor to increase rotational speed of the magnetic platter to the predefined maximum speed in response to the command. The disk drive controller is further configured to, prior to the magnetic platter reaching the predefined maximum speed, access the storage location on the magnetic platter in response to the command. Accordingly, early access to storage locations on the magnetic platter is not substantially hindered by the spin up process.

摘要： Redundancy in storage arrays is used to extend the life of disk drives and conserve power. In an exemplary storage array, a group of storage devices includes y storage devices. Data and redundant information is distributed across the y devices to provide m levels of redundancy. “Spun down devices” are provided by spinning down a set of one or more of up to m of the y storage devices. Meanwhile, data transfers to and from the group of storage devices continue to be serviced. After a predetermined time, the currently spun down disks can be spun up, and new spun down devices are provided by spinning down another set of one or more of m of the y storage devices. An array may include several groups of storage devices, each having its own value for y and m.
