[5] VMware SRM is an automation tool for disaster recovery and allows a RPO of 5 minutes, if vSphere version 6.5 or above replication gets used for replication (RPO = 5 → data loss up to 5 minutes possible). For details please review following, [7] SAP general sizing recommendations is to Scale-Up first. [4] SAP HANA VMs can get co-deployed on a ESXi host server with SAP non-production HANA VMs or any other workload VMs. VMware host restriction for PMem: max.

For any applications or databases that require a RPO < 5 minutes then VMware SRM can get combined with physical synchronous storage replication. SAP S/4HANA ("High-Performance Analytic Appliance") is SAP's ERP for large enterprises. SAP HANA VMware’s HANA certification/support strategy starting with Haswell, is to support a single chipset with 2 versions of the hypervisor and to have a single hypervisor version span normally 2 chipsets. This is the preferred setting as it allows VM host evacuation for instance during a maintenance event. This results in following supported configurations per ESXi host for SAP HANA: Please keep in mind, that the number of SAP HANA VMs depend strongly on the used storage configuration and that the SAP HANA TDI storage KPIs must be met for all SAP HANA production level VMs.
