Cisco DNA Center Appliance

Cisco DNA Center is available as a physical appliance, with the DNA Center ISO image pre-installed and tested. You can deploy this appliance within your network in one of two modes: Standalone: As a single host offering all DNA Center functions. This option is often preferred for initial or test deployments and in smaller network environments. Cluster: As one of a maximum of three hosts, with DNA Center sharing all of its services and data among the hosts. This is the preferred option for high availability and best performance at scale. If you choose standalone mode for initial deployment, you can still add more appliances later to form a cluster.
