Abstract
A method of moving data between first, second, and third storage levels of a hierarchically arranged data storage system is described. The method includes the steps of dividing address space into a plurality of contiguous segments, each of which is further divided into a plurality of contiguous groups. Each of the groups may store a sequence of records, each of which is represented by a sequence of bytes. When it is necessary to move a designated record between the second and third levels of the data storage system, the segment in which that designated record is stored is moved; and when it is necessary to move the designated record between the first and second levels, the group in which that designated record is stored is moved.
