    摘要： 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.

    摘要： A method for allocating resources of a storage system including at least a first and second group of storage devices. The method identifies a first set of resources to be reserved for use by the first group of storage devices, identifies a second set of resources to be reserved for use by the second group of storage devices, and identifies a third set of resources The method then allocates resources from the third set of resources to the first group of storage devices or the second group of storage device according to an allocation algorithm, and restricts use of the first set of resources to the first group of devices and use of the second set of resources to the second group of devices.

    摘要： A set of logical extents, each having compressed logical tracks of data, is mapped to a head physical extent and, if the head physical extent is determined to have been filled, to at least one overflow extent having spatial proximity to the head physical extent. Pursuant to at least one subsequent write operation and destage operation, the at least one subsequent write operation and destage operation determined to be associated with the head physical extent, the write operation is mapped to one of the head physical extent, the at least one overflow extent, and an additional extent having spatial proximity to the at least one overflow extent.
