Book description

Policy-based replication is the successor to Remote Copy for providing replication services for IBM Storage FlashSystem, IBM SAN Volume Controller, and IBM Storage Virtualize for version 8.5.2 and later. This new management model uses volume groups and replication policies to enable the system to automatically deploy and manage replication. This significantly simplifies the tasks that are associated with configuring, managing, and monitoring replication.

Compared to Remote Copy, policy-based replication replicates data between systems with minimal overhead, significantly higher throughput, and reduced latency characteristics.

This IBM Redpaper publication provides a broad understanding of policy-based replication and step-by-step implementation details.

This paper is intended for use by pre-sales and post-sales technical support and storage administrators.
