Performance of an I/O channel with multiple paging drums
Samuel H. Fuller · 1973
For rotating storage units, a paging drum organization is known to offer substantially better response time to I/O requests than is a more conventional (file) organization [Abate and Dubner, 1969; Fuller and Baskett, 1972 ]. When several, asynchronous paging drums are attached to a single I/O channel, however, much of the gain in response time due to the paging organization is lost; this article investigates the reasons for this loss in performance.
