摘要： Data operations, requiring a lock, are batched into a set of operations to be performed on a per-core basis. A global lock for the set of operations is periodically acquired, the set of operations is performed, and the global lock is freed so as to avoid excessive duty cycling of lock and unlock operations in the computing storage environment.
摘要翻译：需要锁定的数据操作被分成一组要在每个核心的基础上执行的操作。定期获取该组操作的全局锁，执行一组操作，并释放全局锁，以避免在计算存储环境中锁和解锁操作的过多占空比。

摘要： Provided are techniques for, in response to establishing each incremental virtual copy from a source to a target, creating a target change recording structure for the target. While performing destage to a source data block at the source, it is determined that there is at least one incremental virtual copy target for this source data block. For each incremental virtual copy relationship where the source data block is newer than the incremental virtual copy relationship and an indicator is set in a target inheritance structure on the target for a corresponding target data block, the source data block is copied to each corresponding target data block, and an indicator is set in each target change recording structure on each target for the target data block corresponding to the source data block being destaged.

摘要： Provided are a method, system, and a computer program product for determining whether to use a repository to store data updated during a resynchronization. Writes to a primary storage are transferred to a secondary storage. A logical copy of the secondary storage as of a point-in-time is established. Writes to the secondary storage in the logical copy received from the primary storage during a logical copy duration after the point-in-time are stored in a repository that comprises less storage space than the secondary storage in the logical copy. The transferring of writes to the secondary storage is suspended. During the suspension writes to the primary storage are indicated in an out-of-synch data structure. A determination is made as to whether available storage space in the repository is sufficient to store writes transferred from the secondary storage while transferring the writes from the out-of-synch data structure in response to ending the suspension of the transferring of writes from the primary to the secondary storages. The repository is used to store data in the secondary storage as of the point-in-time that is to be updated by writes transferred from the primary storage following the ending of the suspension in response to determining that the available storage space in the repository is sufficient to store writes transferred from the secondary storage while transferring the writes indicated in the out-of-synch data structure.

摘要： Provided are a method, system, and article of manufacture for managing write requests in cache directed to different storage groups. A determination is made of a high and low thresholds for a plurality of storage groups configured in a storage, wherein the high and low thresholds for one storage group indicate a high and low percentage of a cache that may be used to store write requests to the storage group. A determination is made of a number of tasks to assign to the storage groups based on the determined high and low thresholds for the storage groups, wherein each task assigned to one storage group destages write requests from the cache to the storage group.
