Book description
In today’s highly competitive and real-time environment, the ability to manage all IT operations on a continuous basis makes the creation of copies and backups of data a core requirement for any IT deployment. Furthermore, it is necessary to provide proactive efficient disaster recovery strategies that can ensure continuous data availability for business operations. The Copy Services functions available with the IBM® System Storage® DS8000® are part of these strategies.
This IBM Redbooks® publication helps you plan, install, configure, and manage the Copy Services functions of the DS8000 when they are used in Open System and IBM i environments. This book provides the details necessary to implement and control each of the Copy Services functions. Numerous examples illustrate how to use the various interfaces with each of the Copy Services.
This book also covers the 3-site Metro/Global Mirror with Incremental Resync feature and introduces the IBM Tivoli® Storage Productivity Center for Replication solution.
This book should be read with The IBM System Storage DS8000 Series: Architecture and Implementation, SG24-8886. There is also a companion book, IBM System Storage DS8000 Copy Services for IBM System z, SG24-6787, which supports the configuration of the Copy Services functions in IBM z/OS® environments.
