IMS Design--Alternatives, Analysis, and Strategies. Revision.
Abstract
It is expected that future high-performance Data Base Management Systems will be required to provide storage capacities and transaction rates several orders of magnitude greater than those of any current systems. To meet the requirements for increased speed, capacity, and availability the IMS Data Base Computer (INFOPLEX) employs a highly parallel, distributed control architecture. The preliminary INFOPLEX design consists of two logically and physically separate components: a physical storage hierarchy and a functional hierarchy. The general structure of an INFOPLEX data storage hierarchy has been developed and a preliminary set of control algorithms has been proposed. This report presents a refind architectural specification and outlines a set of control algorithms which take advantage of theoretical properties of INFOPLEX-like storage systems. Sect 2 discusses the overall rationale for the INFOPLEX hierarchial design concept. Sect 3 presents the details of the design issues and tradeoffs related to performance and reliability, and developes a general strategy for efficient READ/WRITE control and reliable fault handling. Finally, Sect 4 summarizes this report, and indicates the directions for further research. Keywords: Data storage hierarchy, data base management system, hierarchical decomposition, distributed control, data location.
