Abstract: A method and computer program product are provided to ensure a timely secure data erase by comparing a number of secure data erase operations in a queue to a maximum queued threshold, the secure data erase operations corresponding to physical volumes to be secure data erased. In response to determining that the number of secure data erase operations in the queue is greater than the threshold, an average time to a secure data erase deadline is determined. The average time to the secure data erase deadline is compared to a predefined expiration threshold. In response to determining that the average time to the secure data erase deadline is less than the predefined expiration threshold, at least one additional resource is allocated to perform the queued secure data erase operations for completing the secure data erase operations prior to the secure data erase deadline.

Abstract: A method and computer program product are provided to ensure a timely secure data erase by determining an erasure deadline for each physical volume of a plurality of physical volumes and calculating a remaining time for each physical volume. The remaining time is calculated for each physical volume by comparing a current date to the erasure deadline of each physical volume respectively. A secure data erase is performed on the plurality of physical volumes in an order based on the calculated remaining time, where the secure data erase is performed on the physical volume with a shortest calculated remaining time first.

The remaining time is calculated for each physical volume by comparing a current date to the erasure deadline of each physical volume respectively. The physical volumes may then be sorted based on the remaining time and the physical volume with a shortest calculated remaining time will be selectively secure data erased.

Abstract: A method according to one embodiment includes determining whether to reallocate one or more of a plurality of tape drives that are presently allocated for a secure data erase process in response to an evaluation of a quantity of physical volumes to be secure data erased and a minimum queued threshold; and in response to said determination that one or more of said plurality of tape drives is to be reallocated, reallocating the one or more of said plurality of tape drives from the secure data erase process to another function.

Abstract: 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.

Abstract: A method and computer program product are provided to ensure a timely secure data erase by determining whether allocating an additional tape drive would improve secure data erase performance by evaluating a quantity of physical volumes to be secure data erased, a maximum queued threshold, an average time to an erasure deadline and a minimum expiration threshold. An additional tape drive is allocated for the secure data erase process when it is determined that allocating an additional tape drive would improve secure data erase performance.

Abstract: 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.

Abstract: 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 (?), 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.
