HSM Implementation & Customisation


This three-day course is designed, written and presented by the UK's foremost mainframe storage management specialists. It describes and explains how best to implement, customise and utilise HSM. Start-up commands and options are examined in detail, giving practical guidance on performance and availability issues. Customisation of the environment is also covered in detail.
Effective management and monitoring of HSM are important if you are to provide a good service to end-users, and techniques to do this are covered in detail, as is the important and often neglected subject of disaster backup using HSM.

This course is also available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.
