摘要： A method for copying data over a network operating in accordance with a protocol, such as the ESCON protocol, that supports a given logical address range includes establishing a logical path over the network from a primary storage system to a secondary storage system using path logical addresses within the given logical address range. A virtual path is created over the logical path to carry the data from a source storage device in a first logical subsystem of the primary storage system to a target storage device in a second logical subsystem of the secondary storage system, wherein the first and second logical subsystems have respective first and second subsystem logical addresses which are outside the given logical address range. The virtual path is used in a peer-to-peer remote copy (PPRC) operation to copy the data from the source storage device to the target storage device.

摘要： A method for synchronizing data storage systems is provided. The method comprises designating a relationship between a first data storage system and a second data storage system, such that data stored in the first data storage system is copied to the second data storage system, in response to determining that the data stored in the first data storage system has been modified; receiving a first request to modify data stored in a first data block of a first storage volume in the first data storage system, wherein the data block is modified according to the first request; determining that the first data block has not been successfully synchronized when the modified data stored in the first data block is not copied to the second data storage system; and executing a process to retry synchronization of the first data block until synchronization of the first data block is successful, without suspending the relationship while the process is executed.

摘要： A revision control service is included in a hypervisor. The revision control service manages revision control operations relating virtual machine images transparently to the virtual machine. The revision control service interacts with a conventional revision control program, stores relevant revision control metadata external to the virtual machine image with file-level granularity, and synchronizes virtual machine operations with the revision control operations. From the perspective of the virtual machine, the revision control service provides a clean image from which to boot, without modification of the revision control program.

摘要： A system and method for creating N customized disk images from N identical disk images. A computing system creates N identical disk images from a master image. The computing system customize a first identical disk image according to a customization written in customization scripts. While customizing the first identical disk image, the computing system monitors block-level operations applied on the first identical disk image. The computing system applies the monitored block-level operations simultaneously to other N−1 identical disk according to similar customizations written in customization scripts. After applying the block-level operations, the N identical disk images become N customized disk images. Identical Virtual Machines (VMs) operating in the N identical disk images become N customized VMs by operating based on the N customized disk images.

摘要： Two or more received SMS messages can be aggregated into a single consolidated SMS message. The consolidated SMS message can be conveyed across a boundary in accordance with SMS protocols. A fee per SMS message can be incurred for conveying SMS messages across the boundary. The fee can be minimized by use of the consolidated SMS message in lieu of having to convey multiple SMS messages. Once the consolidated SMS message have been conveyed across the boundary, the consolidated SMS message can be parsed or decomposed into its constituent SMS messages, each of which can be conveyed to an intended recipient.

摘要翻译： 两个或多个接收到的SMS消息可以聚合成单个合并的SMS消息。 合并的SMS消息可以根据SMS协议跨越边界传送。 每个SMS消息可能会在跨越边界传输SMS消息。 可以通过使用合并的SMS消息来代替不必传送多个SMS消息来最小化费用。 一旦整合的SMS消息已经跨越边界传送，则合并的SMS消息可以被解析或分解成其组成的SMS消息，每个消息可以被传送到预期的接收者。

摘要： A data storage control unit is coupled to one or more host devices and to one or more physical storage units. Data is stored in one of the storage units and, for data integrity, copied to another storage unit. An updated state of the copy process (metadata) is maintained and updated in metadata tracks in a memory of the storage controller and periodically destaged to corresponding metadata tracks of a storage unit. If the copy process is interrupted, such as by a power failure, an error handling routine commences. Track state fields associated with each in-memory metadata track are initialized to an ‘invalid’ state and background staging of metadata tracks from the storage unit to the memory. After a track is staged, the associated track state field is changed to a ‘valid’ state. If a request is received to access a track of copy state data and the track has been staged (as indicated by the state of the associated track state field), the track is accessed. If the requested track has not been staged, requester waits while the requested track is staged; then the requested track is accessed. Once the error handling routine is completed, normal I/O operations with customer data may resume. Preferably, completion of the error handling routine is independent of the completion of the staging of copy state data tracks.
