ABSTRACT
Production Control in a manufacturing concern can either be an ingratiating system or the most grotesque complex procedure in operation. In a large company, the manual application of the system in question becomes unwieldy and economically impossible. The necessity of mechanizing Production Control thus becomes increasingly obvious, and, because of its effect to the total systems concepts, this mechanization must be handled with the upmost of care...
The next level of consideration becomes the mode of mechanization. The major criteria in Production Control are rapid access in seeking information regarding the location and status on any order or group of orders, immediate addition, updating, and deletion of orders in the file, and the ability to readily purge this file periodically. The establishment of the order file in punched cards would greatly relieve the economics of the system, but access to a large volume of orders over a days time would be extremely burdensome; even its application to magnetic tape would leave us with a cumbersome routine. The third storage device under consideration is the disk file which quite aptly satisfies the requirements: high volume of storage, 10 million BCD characters, or 100,000 sectors of 100 positions each; rapid access to any of these sectors, average seek time 600 milliseconds; and a file that can be readily purged, 150 minutes to dump the disk file on to the tape.

DCD—disk caching disk: a new approach for boosting I/O performance
ISCA '96: Proceedings of the 23rd annual international symposium on Computer architectureThis paper presents a novel disk storage architecture called DCD, Disk Caching Disk, for the purpose of optimizing I/O performance. The main idea of the DCD is to use a small log disk, referred to as cache-disk, as a secondary disk cache to optimize ...
Performance of Two-Disk Failure-Tolerant Disk Arrays
RAID5 disk arrays use the rebuild process to reconstruct the contents of a failed disk on a spare disk, but this process is unsuccessful if latent sector failures are encountered or a second disk failure occurs. The high cost of data loss has led to two-...
