Microsoft's System Center Virtual Machine Manager (SCVMM) is a tool that provides a single location from which you can configure and manage your datacenters. Datacenter components such as virtualization servers, networking components, and storage resources can be managed through the SCVMM tool. You can manage multiple instances of Microsoft's Hyper-V Server virtualization platform and those virtual machines that are hosted on them from within SCVMM.
SCVMM is installed on a device that is different from those hosting your Hyper-V servers.
