Abstract

A cached peripheral storage system has a DASD (direct-access storage device) backing store which is addressable by device, track, and rotational position or sector. Host communications are via a virtual system involving device address DADDR, track, and record number. To access the DASD, the peripheral storage system converts the record number to a sector number and then transfers data between the cache and the DASD. Accessing the record in the cache is by record number.
