The vCenter server is a central management server from Vmware for ESX. With vCenter multiple ESX host servers along with their resources and vm guests can be managed from one location. vCenter also provides additional advanced options and configurations that can enhance the management and redundancy of a multiple ESX host environment. Some features such as High Availability (HA), Distributed Resource Scheduling (DRS), Vmotion, and Storage Vmotion require vCenter. vCenter 4 adds new features like vCenter Linked Mode for managing multiple vCenter servers, Host Profiles to drive consistency between ESX hosts, Vmware vApp which pools vm guests together that makeup an application, the Distributed Virtual Switch, centralized licensing so there’s no more separate license server, Fault tolerance (FT), better performance charts, Storage Vmotion is now built into the GUI, and much more.
