摘要： Host input/output (I/O) operations are performed via a file stored in a non-volatile storage coupled to a storage controller while data structures are being generated in the storage controller to copy data from source logical volumes to target logical volumes. The source logical volumes and the target logical volumes are logical representations of physical storage maintained in a plurality of direct access storage devices. The contents of the file are transferred from the non-volatile storage to one or more of the plurality of direct access storage devices, after the data structures have been generated, wherein the host I/O operations are performed via the file while the contents of the file are being transferred to the one or more of the plurality of direct access storage devices. The host I/O operations to the plurality of direct access storage devices are resumed, in response to transferring entire contents of the file to the one or more of the plurality of direct access storage devices.
摘要翻译：主机输入/输出（I / O）操作通过存储在与存储控制器耦合的非易失性存储器中的文件执行，同时在存储控制器中生成数据结构以将数据从源逻辑卷复制到目标逻辑卷。源逻辑卷和目标逻辑卷是在多个直接访问存储设备中维护的物理存储器的逻辑表示。在生成数据结构之后，文件的内容从非易失性存储器传送到多个直接访问存储设备中的一个或多个，其中通过文件执行主机I / O操作，该文件被传送到多个直接访问存储设备中的一个或多个。响应于将文件的全部内容传送到多个直接访问存储设备中的一个或多个，恢复对多个直接访问存储设备的主机I / O操作。

摘要： Provided are techniques for introducing a delay in responding to host write requests. A percentage of fullness of a write cache is determined. Based on the determined percentage of fullness of the write cache (f), a low cache threshold (L), alpha (α), and k, an amount of delay to introduce into responding to a host write request is determined. Techniques wait the amount of the delay before responding to the host write request although the host write request processing has completed.
摘要翻译：提供了用于引入响应主机写请求的延迟的技术。确定写入高速缓存的百分比。基于所确定的写入高速缓存（f）的百分比，确定低速缓存阈值（L），α（α）和k，引入对主机写入请求的响应的延迟量。尽管主机写入请求处理已经完成，技术仍然等待主机写请求响应之前的延迟量。

摘要： A method to store point-in-time data, comprising establishing a block size, providing source data storage comprising (S) blocks, and target data storage comprising (T) blocks. The method configures (B) source storage segments and (B) target storage segments, and receives updated point-in-time data for original point-in-time data written to an (i)th source storage segment. The method then determines if a (j)th target storage segment comprises available storage capacity to store the original point-in-time data. If a (j)th target storage segment comprises available storage capacity to store the original point-in-time data, the method writes the original point-in-time data to that (j)th target storage segment.
