4.4.3 Multi-server configuration
A multi-server configuration refers to a hierarchical system that consists of a primary management server and multiple management relay servers. In this configuration, you can perform load distribution among administrators or management servers, or support a NAT environment operation. In a multi-server configuration, you can have a maximum of seven levels of hierarchy, with the primary management server being the first level.
Design the system in a multi-server configuration if you want to use JP1/IT Desktop Management 2 in the following environments:
-
To operate JP1/IT Desktop Management 2 separately for each department or network configuration
-
To reduce loads on the network induced by job execution or package distribution when Remote Install Manager is used for data distribution
As in the basic configuration, you can have relay systems in a multi-server configuration. A relay system is considered to belong to one level lower than the management server to be connected by the relay system. If you place a relay system, you will not be able to place any management relay servers on levels that are lower than the level to which the relay system belongs. Note that you cannot place a relay system for a management relay server on the seventh level. For an overview of system configuration with a relay system, see 4.4.2 Basic configuration.
The following figure shows a multi-server configuration.

A maximum of 100 management relay servers can be connected to a management server.
A management relay server can manage a maximum of 30,000 computers.
Restriction on the host names of a management relay servers
The sum of lengths of host names from the hosts directly under the primary management server to the hosts at the lowest level must be no more than 255 bytes, including the separators between the host names. Specify host names for relay systems and management relay servers accordingly.
