2.18 Managing a large system comprised of multiple departments or networks

You can provide multiple management servers depending on the size of the organization or network structure, to perform load distribution among system administrators and management servers, and support systems which involve a NAT environment.

A system with multiple management servers is called a multi-server configuration. A multi-server configuration is constructed hierarchically by a primary management server (that organizes the entire system), and a multiple management relay server (that controls each office or network).

The following figure shows an example system configuration with four-level hierarchy.

Each management relay server connects to one of the management servers (primary management server or management relay server) that resides one level higher in the hierarchy, to report managed information or to have configuration assigned. Each of these destination management servers is called a higher management server. Conversely, each management relay server, as viewed from the destination management server, is called a lower management relay server. In addition, lower management relay servers and management relay servers that connect to the lower management relay servers are collectively called management relay servers under the local server.

In the above example configuration, the following applies:

• The higher management server of the management relay server (A): The primary management server

• The lower management relay server of the primary management server: The management relay server (A) or (B)

• The management relay servers under the local server of the management relay server (A): The management relay servers (A1), (A2), (A11) and (A12)

In addition, the management server to which a managed computer connects, as seen from the managed computer, is called a management server that manages the device. On the other hand, the managed computer, as seen from the destination management server, is called a computer directly under the server.
