Primary Datacenter Secondary Datacenter
• After Failover to DR site, network identity of replicated VMs must get changed to take over production system identity!
• Manual scripts or automated via cluster manager (e.g. SLES HAe)
• QA HANA may get turned off, evacuated or run in overcommit modus to free up resources for replicated PRD systems that get “turned on” after disaster.
