SHARE Live! - Implementing and Using Extended-Addressing Volumes (EAVs)

Project and Program: MVS, MVS Storage Management

Tags: Proceedings, SHARE Atlanta 2016, 2016

Beginning as far back as z/OS version 1.10, IBM introduced Extended Address Volumes, or EAV, yet, surprisingly, few installations seem to have implemented them on a large scale. The increasing demand for z/OS storage is driving new interest in this architecture, which now supports virtually all types of data. EAV volumes can be much larger in size than traditional z/OS volumes, and contain structures, such as cylinder-managed areas, and format 8 and 9 DSCBs, that are different from those found on ordinary z/OS DASD. The speaker will examine what EAV volumes are, how they are defined and used, and their advantages and disadvantages and considerations for implementation.-Steve Pryor-DTS Software, Inc.
