Sizing Requirements

The Sun Management Server host sizing requirements are highly dependent on the number of agents being managed by the server layer and the management activity on these agents. Management activity consists of system-generated activity such as event generation and processing, and user-initiated operations such as browsing data, network discovery, group operations, and system monitoring and diagnosis.

Because of the impact of management activity, the sizing requirements depends on the number, type and configuration of all Sun Management Center add-on packages that are installed on the server, and on the number of managed nodes. In general, the more add-ons that are in use, the greater the management activity and the higher the server hardware requirements.

The following diagram shows the machine classes recommended for the Sun Management Center server as a function of the number of agents under management, and the estimated management activity. The diagram assumes that Sun Management Center consoles are not running on the server machine. The diagram also assumes that there are 5 remote console sessions for the small server; 10 remote console sessions for the medium server; and 15 remote console sessions for the large and extra large server.

The machine classes depicted in the above diagram are representative of classes of hosts with similar performance.

Server performance is adversely affected by running the Sun Management Center console application on the server layer host and by the number of active console sessions. If the server host is not sized generously to support the server layer components, do not run Sun Management Center consoles on the server machine.
