Glossary 131
property
A property is a capability or characteristic of a CIM class. The temperature probe
class, for example, has a property that describes its thresholds for normal, lower
critical, and upper critical ranges of operation. Defining where normal operation
ends and where critical temperatures begin determines when warnings should be
sent to the systems manager for corrective action.
Every property has a Description and a Data Type
. The Description provides a brief
explanation of what a particular managed object does. The Data Type specifies the
form that the values of a property must take. For example, some values are bit fields
and others are integers or strings.
provider
A provider is an extension of a CIM schema that communicates with managed
objects. The provider accesses data and generates event notifications from a
variety of sources. The Dell CIM provider extends the standard CIM schema to
make it easier to manage systems.
MOF
A MOF is a management object file that models objects in a systems management
environment. The MOF models the relationships between different managed
objects. For example, the CIM_RedundancyGroup is a parent class for
components that are so critical to the proper functioning of a system that the
system is designed to have additional critical components. When a critical
component fails, redundancy allows the system to continue operation because
there are other components that can compensate for the loss. The
DELL_PowerSupply and DELL_FanRedundancy classes are derived from the
CIM redundancy group. The relationship is one of child to parent.
RAID
Acronym for redundant array of independent disks.
response file
The file that records the features that an administrator wants to incorporate into
an unattended installation is called a “response file” or an “answer file.”
set operation
An operation used to write or “set” data to MIB variables maintained by the SNMP
agent.
