Book description
This IBM® Redbook captures some of the best practices based on field experience and details the performance gains that can be achieved by implementing the IBM System Storage™ SAN Volume Controller.
This book is intended for very experienced storage, SAN, and SVC administrators and technicians.
Readers are expected to have an advanced knowledge of the SVC and SAN environment, and we recommend these books as background reading:
IBM System Storage SAN Volume Controller, SG24-6423
Introduction to Storage Area Networks, SG24-5470
Using the SVC for Business Continuity, SG24-7371
