In today’s digital age, downtime is not an option. Businesses rely on constant access to critical data to maintain productivity and help ensure customer satisfaction. IBM® Storage Virtualize provides capabilities to safeguard data against a range of threats. Policy-based replication and policy-based high availability protect against site failures by enabling rapid recovery and continuous access to critical workloads.

This IBM Redbooks® publication explores policy-based replication and policy-based high availability, helping you design and operate resilient high availability and disaster recovery (HADR) solutions that minimize downtime and maximize data protection. In addition, this edition covers 3-site replication designs that combine policy-based high availability across two sites with asynchronous DR replication to a third site.

Whether you are a seasoned IT professional or just starting to explore business continuity solutions, this book provides a comprehensive guide to navigating these essential technologies and building a resilient IT infrastructure.

This publication is revised to include the latest advancements in IBM Storage Virtualize 9.1.3.
