VPLEX for SAP and ORACLE RAC:Unmatched High Availability Over Distance

On May 17th, 2012, EMC announced that Oracle has certified VPLEX Metro in a stretch cluster configuration which provides Oracle Real-Application Clusters (RAC) customers with unprecedented high availability and resiliency when used with 2 data centers located up to 100km apart - this new solution provides the capability of having RPO = 0 and RTO = 0 (RPO is Recovery Point Objective, or the amount of data that could be lost when an Oracle system is recovered, while RTO is Recovery Time Objective, or the amount of time needed to fully recover a failed system).

The EMC Solutions Group SAP Engineering team further built upon this ground break solution to implement the separation of the enqueue and message server (the SCS components) from the CI (Central Instance) as described in SAP OSS note 821904 (see attachment below), to provide for maximum high availability for a SAP environment with non-stop availability over a distance of up to 100km, even if the primary data center was to be completely non-operational.
