    Abstract: Provided are a computer program product, system, and method for managing data in a cache system comprising a first cache, a second cache, and a storage system. A determination is made of tracks stored in the storage system to demote from the first cache. A first stride is formed including the determined tracks to demote. A determination is made of a second stride in the second cache in which to include the tracks in the first stride. The tracks from the first stride are added to the second stride in the second cache. A determination is made of tracks in strides in the second cache to demote from the second cache. The determined tracks to demote from the second cache are demoted.

    Abstract: Provided are a method, system, and article of manufacture, wherein a primary storage control unit receives an information unit from a remote host over a fibre channel connection, wherein persistent information unit pacing is implemented over the fibre channel connection. Information is maintained on how many large writes have been received at the primary storage control unit over at least one logical path established over the fibre channel connection between the primary storage control unit and the remote host, wherein a large write is an input/output (I/O) operation for which a number of data information units that are processed exceeds a default value of an information unit pacing credit. The primary storage control unit adjusts an information unit pacing parameter included in a response sent from the primary storage control unit to the remote host, wherein the adjusting is based at least on the information maintained on how many large writes have been received at the primary storage control unit over the at least one logical path.

    Abstract: An apparatus, system, and method are disclosed for concurrently relocating a RAID array. The apparatus includes an identification module, a designation module, and an implementation module. The identification module identifies an availability of a physical device within a donor arrayed storage device to offload a source drive of a relocation enclosure. The designation module designates an available physical device as a target drive and thereby designate the target drive and the source drive as a linked pair. The implementation module implements a mirroring relationship between the target drive and the source drive. The apparatus, system, and method provide a dynamic relocation of the raid array, minimizing system downtime and maximizing efficient utilization of system resources.

    Abstract: Provided are a method, system, and computer program product for determining whether to use a full volume or repository for a logical copy backup space. A determination is made of a source volume to backup using a logical copy operation. The logical copy operation is completed upon indicating the source volume data to backup. During a logical copy duration, point-in-time data in the source volume as of a point-in-time when the logical copy was established is copied to a backup space in response to receiving an update to the point- in-time data. A history of writes to the source volume is processed to determine whether to allocate a full target volume as the backup space providing a corresponding data unit for each data unit in the source volume or allocate a repository as the backup space, wherein the repository uses less storage space than the full target volume. The logical copy operation using the determined full target volume or repository as the backup space is initiated.
