HP-UX System Administrator's Guide: Overview

Managing Multiple Servers from a Single Point of Control Using HP SIM
While the HP Systems Insight Manager can be used to manage a single HP-UX server,
it is probably better to use the “HP System Management Homepage (HP SMH)” for
that purpose.
HP Systems Insight Manager allows you to manage multiple servers called managed
systems from a Central Management Server (CMS). Collectively, the CMS and the managed
systems are referred to as a management domain. The CMS is also a managed system
within its own management domain and can simultaneously be a managed system of
management domains controlled from other CMSs.
The CMS is the server where the HP Systems Insight Manager software resides, and
you can access this software from any network client (any computer capable of accessing
the CMS via a web browser (for a graphical user interface), or via ssh (for a secure
textual user interface). The network clients can be, but do not have to be members of
the managed domain.
NOTE: HP Systems Insight Manager is capable of managing large groups of systems
but for Enterprise-wide operations HP recommends the more powerful OpenView
Suite of tools.
