Central Management allows you to administer multiple Web Gateway appliances in your network as nodes in a common configuration.

A configuration of multiple appliances administered through Central Management is also referred to as a cluster.

When administering a Central Management cluster, you are dealing mainly with:

Nodes — Appliances run as nodes that are connected to each other sending and receiving data to perform updates, backups, downloads, and other jobs.
Node groups — Nodes are assigned to different types of node groups that allow different ways of transferring data.
Scheduled jobs — Data can be transferred according to time schedules that you configure.

NOTE: A Central Management cluster is not necessarily a High Availability (HA) cluster with fail-over functions. To provide these functions, you must also configure the Proxy HA mode for the proxy functions of the appliances that are involved.
