摘要： Provided are a method, system, and program for an adaptor to read and write to system memory. A plurality of blocks of data to write to storage are received at an adaptor. The blocks of data are added to a buffer in the adaptor. A determination is made of pages in a memory device and I/O requests are generated to write the blocks in the buffer to the determined pages, wherein two I/O requests are generated to write to one block split between two pages in the memory device. The adaptor executes the generated I/O requests to write the blocks in the buffer to the determined pages in the memory device.

摘要： Provided are a method, system, and article of manufacture for determining whether to use a full volume or repository for a logical copy backup space. A determination is made of a source volume to backup using a logical copy operation. The logical copy operation is completed upon indicating the source volume data to backup. During a logical copy duration, point-in-time data in the source volume as of a point-in-time when the logical copy was established is copied to a backup space in response to receiving an update to the point-in-time data. A history of writes to the source volume is processed to determine whether to allocate a full target volume as the backup space providing a corresponding data unit for each data unit in the source volume or allocate a repository as the backup space, wherein the repository uses less storage space than the full target volume. The logical copy operation using the determined full target volume or repository as the backup space is initiated.

摘要： An apparatus, system, and method are disclosed for selecting a space efficient repository. A cache receives write data. A destage module destages the data sequentially to a coarse grained repository such as a stride level repository and destages a directory entry for the data to a coarse grained directory such as a stride level directory if the data satisfies a repository policy. In addition, the destage module destages the data to a fine grained repository such as a track level repository overwriting an existing data instance and destages the directory entry to a fine grained directory such as a track level directory if the data does not satisfy the repository policy.

摘要： Provided are a method for selecting a path comprising ports on primary and secondary clusters to use to transmit data at a primary volume to a secondary volume. A request is received to copy data from a primary storage location to a secondary storage location. A determination is made from a plurality of primary clusters of an owner primary cluster for the primary storage location, wherein the primary clusters are configured to access the primary storage location. A determination is made as to whether there is at least one port on the owner primary cluster providing an available path to the secondary storage location. One port on the owner primary cluster is selected to use to copy the data to the secondary storage location in response to determining that there is at least one port on the owner primary cluster available to transmit to the secondary storage location.

摘要： Disclosed is a technique for fault isolation. A first error check is performed on a block of data in storage to determine whether the block of data was corrupted after the block of data was transferred from memory to the storage. When the first error check indicates that the block of data was corrupted, a second error check is performed using the block of data in the memory to determine whether the block of data was corrupted before being transferred from the memory. When the second error check indicates that the block of data was corrupted before being transferred from the memory, it is determined that the block of data was corrupted before being stored in the memory. When the second error check indicates that the block of data was corrupted after being transferred from the memory, it is determined that the block of data was corrupted by at least one of the memory or a formatter that performed the transfer.Additionally disclosed is a technique in which a block of data is transferred from a memory at a first control unit to a memory at a second control unit. At the first control unit, when a second error check at the second control unit indicates that the block of data was corrupted before being transferred from the memory, a third error check is performed on the block of data in memory at the first control unit. When the third error check indicates that the block of data was corrupted, it is determined that the block of data was corrupted at the first control unit. When the third error check indicates that the block of data was not corrupted, it is determined that the block of data was corrupted during transfer from the first control unit to the second control unit.

摘要： Provided is a system, deployment and program for resource allocation unit queuing in which an allocation unit associated with a task is classified. An allocation unit freed as the task ends is queued for use by another task in a queue at a selected location within the queue in accordance with the classification of said allocation unit. In one embodiment, an allocation unit is queued at a first end of the queue if classified in a first class and is queued at a second end of the queue if classified in said second class. Other embodiments are described and claimed.
