ABSTRACT:
A computer having capabilities for hierarchical storage of data, said computer including an interpreter that maps logical user read and write requests to physical block level read and write requests, and a hierarchical performance driver having a disk driver interface for receiving the block level read and write requests from the interpreter, the hierarchical performance driver issuing instructions to read and write data from plural data storage devices in response to block level read and write requests, plural data storage devices having different data access speeds, the hierarchical performance driver monitoring the rates of access of blocks of data stored on the data storage devices and transferring blocks of data accessed infrequently from a faster data storage device to a slower data storage device.
