Supported SAP HANA Systems for VMware virtualization VMware vSphere and SAP HANA HA and Operation Features For additional reference, see SAP Note 1788665 et. The below table states capabilities, supported deployment options and best practices, like minimal vCPU count or maximal vRAM sizes for SAP HANA VMs on VMware vSphere as of May 2016. Please be aware that the use of CPU hot-add feature disables vNUMA and hence may lead to performance degradation. Noticing a certain interest in our CPU hot-add feature, w e would like to highlight that the use of this capability also requires the OS and the SAP HANA database itself to be capable of leveraging the additional resources instantly.We recommend to read VMware KB 144984 and configure hosts correspondingly. We have lately seen some issues with VMs configured with large virtual hardware resources and memory-intensive workloads becoming temporally unresponsive after vMotion has completed.Customers running SAP HANA on VMware shall follow the Architecture Guidelines and Best Practices for Deployments of SAP HANA on VMware vSphere.Supporting more physical compute resources inside a VM ultimately provides more “power” to a virtualized SAP HANA system – this alone is worth considering an upgrade from a vSphere 5.5 to a vSphere 6.0 based SAP HANA environment.Beside increased RAM sizes, vSphere 6 supports also more vCPUs: Up to 128 vCPUs may now be configured and used by a single SAP HANA VM. The support for vSphere 6 allows customers to increase the RAM to up to 4 TB (4080 GB) of existing virtual SAP HANA systems when migrated to vSphere 6.See SAP Note 2315348 and for more details on what’s supported, which deployment options can get used and summary of the best practices. Since May 2016, SAP supports also SAP HANA on vSphere 6 deployments for production workloads.
These and other advanced features – to an large extend found exclusively in virtualization – lower the total cost of ownership and ensures the best operational performance and availability.
