Customers deploy SAP databases and integrated applications in many mission-critical functions, including manufacturing, financial accounting, inventory management, sales, and marketing. These and other functions are the lifeblood of a business, and interruptions or loss of data can be catastrophic. Ensuring the availability of these systems for the businesses that depend on them requires a comprehensive approach to business continuity planning and execution.
SAP landscapes include many separate business-critical modules that all interact and communicate with critical cross-dependent data. Every complex business IT landscape includes not only many SAP systems, but non-SAP systems that feed SAP, receive data from SAP, or are critical stand-alone systems.
Recovering these many interrelated systems, or periodically testing the effectiveness of recovery for business and audit requirements, is a unique requirement of federated systems such as SAP. True cross-database, cross-business system recovery is required for a single point in time, in contrast to recovering many individual databases separately.
Dell PowerMax storage systems are widely used in mission-critical SAP landscapes with traditional databases. The PowerMax family of arrays now provides the same reliable platform for the SAP HANA database. In this solution, Dell PowerMax Symmetrix Remote Data Facility (SRDF) replication with consistency technology, in combination with Dell PowerMax TimeFinder SnapVX, enables SAP customers to perform local and remote replications consistently across databases to reliably restore or test the many business functions in the total SAP landscape. SRDF and SnapVX enable complete high availability and business continuity for mission-critical environments for synchronous and asynchronous data protection.
Note: SnapVX is part of TimeFinder.
Most customers who use the SAP HANA in-memory database in TDI deployments maintain a copy of the data either locally or remotely to protect their mission-critical applications and the SAP HANA database against disasters, hardware or software failures, and human errors.
While SAP HANA offers disaster recovery (DR) support with backups or with SAP HANA system replication, SAP HANA storage-based replication enables customers to seamlessly integrate SAP HANA into their existing business continuity solutions.
