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： A method for managing a data storage system includes maintaining a record predictive of locations to which data are to be written on the primary storage subsystem by a host processor. Upon receiving data from the host processor at the primary storage subsystem to be written to a specified location on the first non-volatile storage media, if the specified location is not included in the record, the record is updated responsively to the specified location. The primary storage subsystem signals the host processor that the data have been stored in the data storage system responsively to receiving the data and, if the specified location was not included in the record, responsively to updating the record.

摘要： A novel and useful mechanism and method for writing data updates to a data cache subsystem of a storage controller. Updates received by the storage controller requiring storage allocation on a repository volume are delayed prior to being written to the data cache subsystem. The delay is based on the storage utilization of the repository volume. As the utilization of the repository volume increases, the cache write delay increases, thereby limiting the possibility that there will still be any updates in the data cache subsystem waiting to be destaged to the repository volume when the repository volume is fully utilized. When the repository volume is fully utilized all writes to the data cache of updates that will cause destage of tracks in the repository volume are stopped, thereby causing an infinite delay.
摘要翻译：一种用于将数据更新写入存储控制器的数据高速缓存子系统的新颖有用的机制和方法。存储控制器需要在存储库卷上进行存储分配的更新在被写入数据高速缓存子系统之前被延迟。延迟是基于存储库卷的存储利用率。随着存储库容量的利用率的增加，高速缓存写入延迟增加，从而限制了当存储库卷被充分利用时，数据高速缓存子系统中仍然存在任何等待被转储到存储库卷的更新的可能性。当存储库卷被充分利用时，所有写入数据高速缓存的数据缓存会导致资源库容量中的磁道出现故障，从而导致无限延迟。

摘要： Provided are a method, system, and article of manufacture for splitting writes between a storage controller and replication engine. A splitter executing in a storage controller manages access to primary volumes. An initialization command is received to communicate with a replication engine. A replication command is received for one primary volume and the primary volume is indicated as subject to replication. A write request is received to write data to a target primary volume of the primary volumes that is indicated as subject to the replication. The data in the write request is written to the target primary volume. The data in the write request is sent to the replication engine. The replication engine executes a copy services function associated with the target primary volume to write the data to a replication engine volume.
