摘要： Apparatus and associated methodology involving use of a multiple-core processor. A reserved hard allocation of resources partition (HARP) dedicates physical resources for operably supporting a first processing function. The dedicated resources of the reserved HARP include a reserved physical memory that is sized in relation to data processing requirements of the first processing function. The dedicated resources of the first HARP also include a command buffer residing in the reserved physical memory. The dedicated resources of the first HARP also include a reserved physical core of the multiple core processor. The apparatus also includes a second HARP having resources that are used for operably supporting a different second processing function. The second HARP resources operably put transaction requests from the second processing function to the command buffer in the first HARP.

摘要： A method for communicating between devices in a network includes creating an I/O tunnel between a first device and a second device through the network. The I/O tunnel is associated with I/O resources in both the first device and the second device, and wherein at least one of the I/O resources comprises a buffer resource. A data transfer operation may be sent between the first device and the second device by consuming at least some of the I/O resources associated with the I/O tunnel. A plurality of commands or a plurality of responses can be aggregated into a single buffer resource. Upon completion of the data transfer operation, the I/O resources that are consumed are automatically renewed.

摘要： A system and method for replicating data between a plurality of storage locations. Each storage location has a controller with a port to a data communication network and a pool of storage. A logical unit (LUN) of storage is implemented at each storage location such that each implemented LUN comprises a substantially complete replica of the data stored in each other LUN. At least two of the controllers at the plurality of storage locations present their implemented LUN as an active device to the one or more host systems for receiving operational data access requests. Preferably, there are three or more storage locations in the system. Preferably, there are three or more storage locations in the system and each storage location can behave as a source location or a destination location for a particular operational data transaction.

摘要： A system and method for identifying a failed storage device in a storage system comprising a plurality of storage devices connected by a ring-type network is disclosed. In one embodiment, when a storage device fails, all storage devices on the ring-type network are disconnected to re-establish communication on the ring-type network. An iterative process of connecting a subset of storage devices to the ring-type network and testing communication on the ring-type network is performed until communication on the ring-type network is re-established. Then, individual storage devices are connected to the ring-type communication until the connection of a storage device causes communication on the ring-type network to fail, thereby identifying the failed storage device. In another embodiment, devices in a reporting group are tested on a shelf-by-shelf basis.

摘要： A storage area network (SAN) controller and method for storing and replicating data between sites in a storage area network in which storage controllers at each site implement storage virtualization. A storage cell is implemented at each site comprising at least one storage controller and a pool of physical storage coupled to the controller. A copy set comprising a logical unit (LUN) of storage, referred to as a member, in each of the storage cells is defined. As operational data transactions are performed against one of the members of a copy set, they are replicated, immediately or after a delay, in each other member of the copy set. As changes are made to dependent attributes such as size of one member of the copy set, the change is replicated in each other member of the copy set automatically. Changes can be made in the independent attributes such as size of each member of the copy set independently of other members of the copy set.

摘要： A system which provides a completely redundant configuration including dual Fibre Channel fabric links interconnecting each of the components of two data storage sites, wherein each site comprises a host computer and associated data storage array, with redundant array controllers and adapters. The array controllers perform a command and data logging function which stores all host write commands and data ‘missed’ by the backup storage array during a situation wherein the links between the sites are down, the remote site is down, or where a site failover to the remote site has occurred. Log units are used to store, in order, all commands and data for every transaction which was ‘missed’ by the backup storage array when one of the above system error conditions has occurred. The system provides rapid and accurate recovery of backup data at the remote site by sending all logged commands and data from the logging site over the link to the backup site in order, while avoiding the overhead of a full copy operation.

摘要： A warmswap operation to replace modules in a mirrored cache system has been accomplished by disabling mirrored write operations in the cache system; testing the replacement memory module in the cache system; and restoring the mirrored data in the cache system. The restoring operation is accomplished by first quiescing write operations to stop writing data in the cache system not backed up in non-volatile data storage. Then data is copied from surviving memory modules to the replacement module, and the cooperative interaction of the surviving memory modules with the replacement memory module is validated. The validating operation verifies the cache modules are ready and the controllers are synchronized. After validation the quiesced write operations are un-quiesced, and mirrored-write operations for the cache system are enabled.
