Management Server Considerations
Hard drive capacity and the number of manageable servers to be managed are the primary considerations for your management server.
-
Hard drive capacity is affected by two factors: the number of OS distributions that are to be provisioned, and the log files generated by N1 System Manager. OS distributions are stored in the/var file hierarchy on the management server. Allocate 3 Gbytes for each OS distribution and its associated profiles and scripts.
Sufficient disk space should also be allocated for the N1 System Manager event logs. Log file size depends on how you set up event monitoring and the amount of detail chosen for each log. The n1smconfig utility is used to configure logging during initial N1 System Manager configuration, and can subsequently be used after the system is in production to reconfigure logging. For further information, see Chapter 6, Monitoring Servers and Server Groups, in Sun N1 System Manager 1.3 Discovery and Administration Guide.
-
System processing is affected by three major factors: The number of managed servers being managed, the types of monitoring being performed on the managed servers, and the number of jobs running on the management server.
The following table provides sizing guidelines for the management server.
