Course Description
Do you need to learn about the architecture associated with z/OS data storage devices that includes the media characteristics of current Direct Access Storage Device (DASD) and tape subsystems? In this entry-level course, look at how data is stored on traditional DASD (3380's and 3390's) and how traditional DASD concepts are emulated in today's array disk technology (specifically, the Enterprise Storage Server). Also, examine the flow of an Input/Output (I/O) operation and how concepts, such as caching, remote mirroring, and point-in-time backups work. Review the current tape subsystems and how data is stored in a Virtual Tape Server.
Learn the prerequisite information you need for further training in specialized areas, such as storage administration, storage subsystem configuration, and system measurement and tuning.

Audience
This is a course for anyone who needs the basic knowledge and fundamental concepts associated with data storage devices. In particular, storage administrators, system programmers, and operations staff who are responsible for developing storage management techniques or who need to understand issues associated with storage management.
Pre-requisites
You should have:
- Basic knowledge of System z terminology and concepts is helpful.
Course Objective
- Identify the concepts of Redundant Array of Independent Disks (RAID) technology and understand the fundamental difference between traditional DASD and Array DASD
- Describe the tape media and data recording mechanisms used in the current generation of tape technology
- Correlate data set formats and organization with supported access methods and media
- Trace the flow of an I/O request through operating the components of the storage subsystem and identify system and potential performance bottlenecks
- Discuss the effect of cache, DASD fast write, and write penalties on the response time of an I/O operation
- Specify characteristics of data that exploit hardware features, such as cache, remote mirroring, and point-in-time backups
Key topics
- Overview of DASD hardware
- Data structure organization and access
- The anatomy of an I/O operation
- Array DASD introduction
- The Enterprise Storage Server
- Tape storage
- The Virtual Tape Server
