COMPARE VMWARE VSPHERE 6.5 VS 6.7 SOFTWARE
In our vcbench workload, we measure not just the overall operations per second, but also the average latencies of individual operations like powerOn (which exercises the majority of the DRS software stack).
Note that this is different from the setup used in our previous blog about vCenter 6.5 performance improvements.
This setup represents a high-consolidation environment with 125 VMs per host. What is cluster scale? Here, it is an environment that includes a vCenter server that is configured for the largest vSphere cluster that VMware currently supports, namely 64 hosts and 8,000 powered-on VMs. Let us first explain what all metrics compared at cluster scale limits means. We also briefly explain some of the technical details behind these improvements. power-on virtual machine)Īs senior engineers within the VMware Performance and vSphere teams, we are writing this blog to provide more details regarding these numbers and to explain how we measured them. Moreover, with vSphere 6.7 vCSA delivers phenomenal performance improvements (all metrics compared at cluster scale limits, versus vSphere 6.5):ĢX faster performance in vCenter operations per secondģX faster DRS-related operations (e.g. In a recent blog, the VMware vSphere team shared the following performance improvements in vSphere 6.7 vs.
