摘要： Described are techniques and criteria used in connection with cache management. The cache may be organized as a plurality of memory banks in which each memory bank includes a plurality of slots. Each memory bank has an associated control slot that includes groups of extents of tags. Each cache slot has a corresponding tag that includes a bit value indicating the availability of the associated cache slot, and a time stamp indicating the last time the data in the slot was used. The cache may be shared by multiple processors. Exclusive access of the cache slots is implemented using an atomic compare and swap instruction. The time stamp of slots in the cache may be adjusted to indicate ages of slots affecting the amount of time a particular portion of data remains in the cache. Each director may obtain a cache slot from a private stack of nondata cache slots in addition to accessing a shared cache used by all directors.

摘要： A method for controlling exclusive access to a resource shared by multiple processors in a data storage system includes providing a system lock procedure to permit a processor to obtain a lock on the shared resource preventing other processors from accessing the shared resource and providing a faked lock procedure to indicate to the system lock procedure that a processor has a lock on the shared resource where such a lock does not exist, and wherein the faked lock procedure prevents another processor from obtaining the lock on the shared resource, but does not prevent other processors from accessing the shared resource. A data storage system according to the invention includes a shared resource, a plurality of processors coupled to the shared resource through a communication channel, and a lock services procedure providing the system lock procedure and the faked lock procedure. In one embodiment, the shared resource is a cache and the system lock procedure permits a processor to lock the entire cache whereas the faked lock procedure is implemented by a processor seeking exclusive access of a cache slot.

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.
