Storage management administration & exploitation

This course describes and explains how to implement and exploit the features provided by the z/OS storage environment, and covers SMS in particular. It examines both hardware and software features and explains how to fully exploit them. The course will gives attendees a detailed knowledge of how best to design and test the SMS Constructs and ACS routines. It provides a basis for evaluating standards and for establishing an optimised System Managed Storage (SMS) environment. The course also explains key components such as catalogs, VTOCs and I/O definitions. There are a number of online practical sessions during the course which, among other things, teach how to write optimised ACS routines.

On successful completion of this course attendees will be able to:

  • explain IBM's storage management concept as implemented through SMS
  • exploit the hardware features utilised by SMS
  • define I/O devices and get them recognised by z/OS
  • define VTOCs and VTOCIXs
  • administer ICF Catalogs
  • define and maintain data classes, storage classes, management classes and storage groups
  • write and maintain optimised ACS routines
  • audit and optimise the SMS environment
  • describe the functions of HSM.
