Object storage hierarchy management

Abstract
The Object Access Method (OAM) component of MVSIData Facility Product is responsible for the stor-age, retrieval, and management of objects in IBM MVSIESA" ImagePlus" systems and in other applica-tions. The OAM Storage Management Component is the subcomponent of OAM that provides storage man-agement for objects stored within an object storage hierarchy. Storage management is a cyclic procedure which assures that data are stored in conformity to a policy defined by the data processing storage adminis-trator. During a storage management cycle, the OAM Storage Management Component (OSMC) selects ob-jects for processing based on requirements for backup, expiration, or service level changes. This pa-per describes the concepts of object storage manage-ment using a storage hierarchy that contains DASD and optical disk storage.
