Book description
This IBM® Redbook®s publication provides a practical understanding of theI BM XIV® Storage System copy and migration functions. The XIV Storage System has a rich set of copy functions suited for various data protection scenarios, which enables clients to enhance their business continuance, data migration, and online backup solutions. These functions allow point-in-time copies, known as snapshots and full volume copies, and also include remote copy capabilities in either synchronous or asynchronous mode. These functions are included in the XIV software and all their features are available at no additional charge.
The various copy functions are reviewed in separate chapters, which include detailed information about usage, and also practical illustrations.
This book also explains the XIV built-in migration capability, and presents migration alternatives based on the SAN Volume Controller (SVC).
Finally, the book illustrates the use of IBM Tivoli® Storage Productivity Center for Replication to manage XIV Copy Services.
This book is intended for anyone who needs a detailed and
practical understanding of the XIV copy functions.
