VMware vCenter Server 6.0 brings significant improvements over previous vCenter server versions with respect to cluster size and performance. vCenter Server 6.0 supports up to 64 ESXi Hosts and 8000 VMs in a single cluster. A new white paper, ” VMware vCenter Server 6.0 Cluster Performance “, describes the improvements along several dimensions:
- VMware vCenter 6.0 can support more hosts and more VMs in a cluster.
- VMware vCenter 6.0 can support higher operational throughput in a cluster.​
- VMware vCenter 6.0 can support higher operational throughput with ESXi 6.0 hosts.
- VMware vCenter 6.0 VCSA can support higher operational throughput in a cluster, compared to vCenter Server on Windows.
Here is a chart from the white paper summarizing one of the key improvements: operational throughput in a cluster:
