Benefits Running SAP Applications on VMware vSphere

• SAP HANA (Suite on HANA as well as BW/BI) in production fully supported by SAP and VMWare

• Infrastructure is always available and standardized for SAP

• Improved Infrastructure (compute, storage and network) planning process

• Higher infrastructure utilization rates-(Multiple production SAP HANA VM’s on a single certified physical server is supported by SAP in vSphere 6.x)

• Higher SLAs at less costs (out of the box 99.9% availability) HANA Auto Restart with VMWareHA

• Enabling SAP HANA specific monitoring and reporting with vROPS, SolMan through BlueMedora

• In house experience with VMWare

storage replication

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.

DR HANA VMs are not needed when replicated via storage
