DASD

The more often that the data requested by applications is in memory rather than out on DASD, the better overall performance will be.

DASD is cheap, and the time on the wire might be only a small part of the total time in the process.

The term DASD applies to disks or to simulated equivalents of disks and magnetic drums.

The total direct access storage device (DASD) attached to this physical system, through its various fiber channels, was well over 200 TB.

A storage group is a set of volumes on a physical storage device, DASD (direct access storage devices) on the mainframe.

This saves you from using up a real device and on DASD tracking and management.

Partitioned data sets are mostly used to store application programs and JCLs. They can only be stored on DASD.

Let's simulate this scenario, assuming that objects stay six months in DASD, three years in external storage, and seven years in tapes.

In other words, end users will not realize where the document is sitting, either DASDs, external disk, or tape.

We distributed the DASD for the user mail boxes over these mount points.

Typically, users will store objects into DASD initially.

Represent the first and second partitions of the first DASD device in your system.

Therefore, the first step is to define the shared DASD in HACMP.

Also, we added four more CPs, increased the memory to 26 GB, and added more DASD to support the full user load.

Such designs not only waste DASD space, but also require higher resource consumption for many DB2 operations.

This is achieved by using a transactional log, based on a recoverable media (such as physical DASD).
