High availability and disaster recovery solutions for SAP are essential. Tier 1 application outages are costly and disruptive to the business. Even short periods of planned downtime for maintenance events like software updates or hardware upgrades can negatively impact end-user and IT productivity as well as critical business processes. Larger unplanned outages can be devastating, with significant business disruption, missed revenue, and lost reputation. By nature, SAP® workloads are often business critical, making downtime increasingly unacceptable. For example, losing the ability to process high-volume transactions or perform real-time analytics can have substantial negative business impacts.
