Abstract:
Provided are a method, system, and article of manufacture, wherein a storage manager application implemented in a first computational device maintains a virtual logical volume that represents a plurality of segments of a linear storage medium of a secondary storage, wherein the virtual logical volume and the plurality of segments are created by the storage manager application. A request for data is received at the first computational device, from a second computational device. The storage manager application moves selected segments of the plurality of segments from the linear storage medium of the secondary storage to a cache storage, in anticipation that the requested data is included in the selected segments that are moved from the linear storage medium of the secondary storage to the cache storage.
