ABSTRACT:
A mass storage/retrieval module for controlling the storage and retrieval operations of massive amounts of data in peripheral devices such as tape, disk, optical, etc. provides for a buffer memory system in each of the interface control modules which permit simultaneous and concurrent writing to buffer storage and reading out of buffer storage through multiple ports for high rates of data transfer operations. Redundancy and high reliability is provided in that each module of the system has dual busses and live replacement units such that, upon failure, an alternate unit can carry the circuitry requirements until the failing unit has been replaced.
