DCImanager Administrator

What is a location

An administrator can add servers to DCImanager regardless of their geographical location and data centers. Remote servers can be grouped according to their location. To do so, you can utilize locations in the control panel. 

A location is an interface that allows DCImanager to manage servers from one data center. Every location in the data center has a special server that is used as a DHCP server and storage of OS templates for all servers in the location. A server must be physical or virtual based on KVM virtualization. A server with DCImanager can be used as a location. Learn more in the article How to add a location
