    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: 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.

    摘要: A storage system includes a backend storage unit for storing electronic information; a controller unit for controlling reading and writing to the backend storage unit; and at least one of a cache and a non-volatile storage for storing the electronic information during at least one of the reading and the writing; the controller unit executing machine readable and machine executable instructions including instructions for: testing if a frequency of non-volatile storage full condition has occurred one of above and below an upper threshold frequency value and a lower threshold frequency value; if the frequency of the condition has exceeded a threshold frequency value, then calculating a new size; calculating an expected average response time for the new size; comparing actual response time to the expected response time; and one of adjusting and not adjusting a size of the non-volatile storage to minimize the response time.

    摘要: Provided are a computer program product, system, and method for determining server write activity levels to use to adjust write cache size. Information on server write activity to the cache is gathered. The gathered information on write activity is processed to determine a server write activity level comprising one of multiple write activity levels indicating a level of write activity. The determined server write activity level is transmitted to a storage server having a write cache, wherein the storage server uses the determined server write activity level to determine whether to adjust a size of the storage server write cache.
