The management domain is a collection
of resources that are placed under the control of the SCM. The dark-shaded
area in Figure 1-1 “Management Domain” represents a
management domain. The individual resources are called managed nodes.
One node in each management domain is the central management server
(CMS)
.
For more information about the CMS, see “Central
Management Server”.
Nodes |

Resources that make up a management domain are called managed nodes.
A node can be any device on the network that can communicate with
SCM, which includes servers, printers, workstations, hubs, and routers.
In most cases, these devices will have an IP address or a MAC address
associated with them.
Each node can have a variety of management protocols
or management applications installed. SCM tools use these protocols
or applications to perform tasks, monitor software, and monitor
hardware on the managed nodes.
Node Groups |
|
Node groups are
a powerful way to divide and organize your management domain into manageable
units. Often the nodes that belong to a node group have something
in common such as operating system, backup schedule, system function,
or hardware type. Working with node groups increases your efficiency
because you can perform a task on each node in a node group by performing
a single task.
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 “Node Groups in a Management Domain”, 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.
