Truth: In the properly designed environment with appropriate supporting dependencies and assets, SAP HANA virtual machines are simply another application running on the vSphere hypervisor, achieving also the goals of lower TCO, better service levels and faster time-to-value.ECC 6.0 EHP7 IDES software component list is provided in the following table for your reference. Myth: Virtualizing of SAP HANA requires a fundamental change in the operation and additional resources needed. With this support it is possible to scale-out SAP HANA until 16 nodes and up to 64 TB of memory for BW on HANA workload. Truth: SAP HANA Scale-out is officially and fully supported by SAP and VMware since SAP HANA 1.0 SPS 09. Myth: VMware can’t be scaled-out for SAP HANA workload on vSphere hypervisors.
SAP HANA VMWARE 6.0 ARCHIVE
Truth: SAP and VMware invested considerable resources to create best practices for SAP HANA workload on VMware vSphere to reduce the complexity and to archive the optimal support results. Myth: Customers can ignore the recommendations of the SAP HANA on VMware best practices guide. Truth: VMware vSphere vMotion can be used successfully to migrated running virtual machines in a SAP HANA environment when the best practices are followed.Īrchitecture Guidelines and Best Practices for Deployments of SAP HANA on VMware vSphere Guide Myth: VMware’s technology vSphere vMotion for the live migration is incompatible with SAP HANA workload. In the case of VMware products and technologies VMware vCenter Site Recovery Manager (SRM) is supported for SAP HANA workload on VMware vSphere. Truth: Disaster a Recovery is supported by different technologies and products. Myth: Disaster Recovery (DR) is not possible and not supported for virtualized SAP HANA workload. Truth: After two years of intense testing, not a single functional error occurred while running SAP HANA on VMware platform based on vSphere hypervisor. Myth: The SAP HANA data is not accurately and/or properly stored on a virtual environment and could be causing functional errors. Virtualized SAP HANA performance evolution with the HPE ConvergedSystem 500 and VMware vSphere 6.0 More details of a “BWL-EML” benchmarks are documented () by HPE with a delta of 5%. But, in the past “physical to virtual” benchmarks showed an overhead of less than 10% compared to bare metal servers. Truth: There is a performance overhead by the hypervisor.
Myth: The virtualization overhead degrades the performance severely. VMware Announces Support from SAP of VMware ESX Server for Production Environments “SAP and VMware will assist joint customers in collaborative support services and problem resolution, backed by a global technology partnership agreement and dedicated support staffing.” Truth: Both, SAP and VMware have a long strategic partnership and together both companies are providing a joined support for virtualized SAP HANA on VMware. Myth: On technical or engineering related challenges with virtualized SAP HANA you’re on your own. SAP Note 2393917 - SAP HANA on VMware vSphere 6.5 and 6.7 in production.
“SAP HANA VMs can get co-deployed with SAP non-production HANA or any other workload VMs, as long as the production SAP HANA VMs are not negatively impacted by the co-deployed VMs. Truth: Co-deployments besides SAP HANA virtual machines in production is supported independent of SAP HANA or Non-SAP HANA virtual machines on the same vSphere host. Myth: Other applications are not supported on the same hosts besides SAP HANA virtual machines. SAP Note 2393917 - SAP HANA on VMware vSphere 6.5 and 6.7 in production Due to the underlying certified hardware OLAP can only use with maximum 3TB, the actual usable RAM is a matter of SAP Sizing.” “The maximum size for Skylake of a virtual SAP HANA instance is limited CPU-wise by the maximum size of a virtual machine on VMware vSphere 6.5 and 6.7 release, which is 128 vCPUs on 4 Sockets (4 sockets on up to 8 socket hardware), and 6TB of RAM.
Truth: The supported limitation of virtual machine memory size is 6 TB on OLTP workload and 3TB on OLAP workload – both on Intel Skylake CPUs. Myth: Limited memory size of SAP HANA on vSphere, the largest implementation is 1 TB of virtual memory. This blog article shows the most named myths and their truths. There are some myths in the field about the virtualization of SAP HANA on VMware.
