HP Servicecontrol Manager Introduction
The Management Domain
Chapter 1
11
Nodes can belong to one or more node groups, but they do not have to belong to a node
group. A node group cannot be a member of another node group, but all the nodes of a
node group can be completely contained within another node group. In Figure 1-2,
Node11 is in node groups B and C. Nodes 9 and 10 represent nodes that do not belong to
a node group.

Central Management Server
The central management server (CMS) is the node in the management domain that
executes the SCM software and initiates all central operations within the SCM. In
addition to the SCM software, the CMS maintains a data repository using MySQL
relational database for storage of persistent objects. Typically, servers for the
multiple-system aware applications, such as Software Distributor (SD) and Ignite-UX
(I/UX), also reside on the CMS. These applications are not required to reside on the
CMS; they can reside anywhere on the network.
Since the CMS is a node within the management domain, it manages itself as part of the
domain. You can add the CMS as a node within another management domain if you want
to manage it using a separate CMS.
