This IBM® Redpaper™chapter publication explains the configuration, relocation, and verification of the IBM Geographically Dispersed Resiliency on IBM Power Systems™ solution to protect SAP HANA and SAP NetWeaver applications.
This is a supplemental guide to IBM Geographically Dispersed Resiliency for IBM Power Systems, SG24-8382, which outlines the specifics when using Geographically Dispersed Resilience for SAP applications, including SAP HANA.
Business continuity is a part of business operations. Downtime and disruptions can cause financial losses and impact public relations and trust in your business. Also, governments in many countries require businesses to have disaster recovery (DR) plans demonstrate regularly that the recovery plan tests successfully.
IBM Geographically Dispersed Resiliency for IBM Power Systems is a DR solution that covers servers but can include business applications. In particular, this solution provides features to support the high availability (HA) of logical partitions (LPARs) running SAP HANA and SAP NetWeaver applications.
IBM Geographically Dispersed Resiliency enables simplified DR management for IBM Power Systems servers. In fewer than 10 steps, administrators can deploy and configure the solution. This is the only solution on IBM Power Systems that offers nondisruptive DR testing.
