This section provides guidelines for determining your management server and switch needs. The following topics are discussed:
Hard drive capacity and the number of provisionable 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 each N1 System Manager job. 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 5, Monitoring Your Servers, in Sun N1 System Manager 1.2 Administration Guide.
System processing is affected by three major factors: The number of provisionable servers being managed, the types of monitoring being performed on the provisionable servers, and the number of jobs running on the management server.
The following table provides sizing guidelines for the management server.

Switch requirements are determined by the following factors:
Whether you have added a third 1–Gbit NIC to the management server
The number of management ports on each provisionable server
The number of provisionable servers to be connected to the switch
The Sun Fire V20z and V40z servers have two management ports, and subsequently can be daisy-chained. For further information, see Appendix A, Alternate Sun Fire V20z and V40z Reference Configuration.
The network topology you have chosen
The following worksheet can assist you in determining the total number of switch ports by type that you will need on your switch or switches.
Table 2–6 Switch Port Requirements Worksheet
Use the above totals to determine your switch requirements, and then connect the servers and switches according to your site plan.
