VMware vCenter Server is the centralized platform for managing a VMware vSphere environment. It is the primary point of management for both VMware ESXi server virtualization and VMware vSAN. It is also the enabling technology for advanced capabilities such as vSphere vMotion, vSphere Distributed Resource Scheduler, and vSphere High Availability.
vCenter scales to enterprise levels. A single vCenter can support up to 2,500 hosts (Dell VxRail nodes) and 40,000 powered-on virtual machines. For the latest recommended limits, see . vCenter supports a logical hierarchy of data centers, clusters, and hosts. This hierarchy allows you to separate resources by use cases or lines of business and enables resources to be moved as needed dynamically. These resource changes are all performed from a single interface.
