ABSTRACT:
In an information processing method and system including a secondary storage, a primary storage for storing data blocks of the secondary storage and a directory containing control information for the data blocks stored in the primary storage, the directory is consulted to determine whether a desired data block is in the primary storage, and if it is, the data block is read from the primary storage. The control information of the directory contains pairs of addresses on the primary storage of the data blocks stored in the primary storage and the addresses on the secondary storage.
