In Mainframe, DASD (Direct Access Storage Device) volumes are used for storing data and executable programs (including the operating system itself), and for temporary working storage. IBM 3390 model DASD disk drives are commonly used on mainframes. The 3390 Model 9 was the last Single Large Ex...
A storage device that supports direct access is referred to as a direct access storage device (DASD). Each data block on a DASDvolumeis assigned a unique address that represents a distinct location. Direct access storage devices use electrical or electromechanical mechanisms to provide immediate acce...
Additional DASD is required at month end and year end. Collective Form: An Exploration of Large-Group Writing 1998 Outstanding Researcher Lecture Mainframe users - and eventually Unix and NT users - will be able to carry out regular point-in-time saves, for backup, Y2K testing, business intell...
Libraries can use the extended addressing space (EAS) of an extended address volume (EAV) DASD volume You can place CICS DFHRPL libraries, such as SDFHLOAD, and dynamic program LIBRARY concatenations, in the EAS of an EAV DASD volume. In previous releases, if the DFHLDSVC module tried to...
Mainframe workers use the terms central storage, real memory, real storage, and main storage interchangeably. Likewise, they use the terms virtual memory and virtual storage synonymously. What is an address space? The range of virtual addresses that the operating system assigns to a user or separa...

It keeps the rest of the code and data in files called page data sets on auxiliary storage, which usually consists of a number of high-speed direct access storage devices (DASD). Virtual storage, then, is this combination of real and auxiliary storage. z/OS uses a series of tables and ...
