Abstract

Peripheral storage systems employ buffer stores for giving a virtual backing store status to a plurality of users. The activity of the users with respect to the plurality of buffer stores can require a balancing between the buffer stores, replacement control for replacing data in the buffer with data from a backing store for enhancing operation. When such load balancing/replacement occurs, based upon user activity, certain data may be purged from the buffer store. The result of such purging requires adjusting the backing store (the tape or disk) such that access to data in the backing store is enhanced. For example, the virtual position of a tape, as represented by data stored in the buffer, may include several blocks of data.
