CIM_SystemResource
The CIM_SystemResource class listed in Table 3-38 provides access to system resources from an operating system. SystemResources consist of interrupt requests (IRQs) and direct memory access (DMA) capabilities.

Class Name:
CIM_SystemResource
Parent Class:
CIM_LogicalElement
CIM_IRQ
The CIM_IRQ class described in Table 3-39 contains IRQ information. An IRQ is a signal that data is about to be sent to or received by a peripheral device. The signal travels by an IRQ line to the microprocessor. Each peripheral connection must be assigned an IRQ number. For example, the first serial port in your computer (COM1) is assigned to IRQ4 by default.
Indicates the availability of the IRQ. Values for the Availability property are as follows:
Other
Unknown
Available
In use/not available
In use and available
uint16
TriggerLevel
Indicates whether the interrupt is triggered by the hardware signal going high or low. Values for the TriggerLevel property are as follows:
Other
Unknown
Active low
Active high
uint16
TriggerType
Indicates whether edge (value=4) or level triggered (value=3) interrupts occur.
Other
Unknown
Level
Edge
uint16
Shareable
Indicates whether the IRQ can be shared. A value of TRUE indicates that the IRQ can be shared.
Boolean
Hardware
Indicates whether the interrupt is hardware- or software-based. (A value of TRUE indicates that the interrupt is hardware based.) On a personal computer, a hardware IRQ is a physical wire to a programmable interrupt controller (PIC) chip set through which the microprocessor can be notified of time critical events. Some IRQ lines are reserved for standard devices such as the keyboard, diskette drive, and the system clock. A software interrupt is a programmatic mechanism to allow an application to get the attention of the processor.
Boolean
CIM_MemoryMappedIO
The CIM_MemoryMappedIO class explained in Table 3-40 addresses both memory and port I/O resources for personal computer architecture memory mapped I/O.
Identifies the starting address of memory mapped I/O.
uint64
EndingAddress
Identifies the ending address of memory mapped I/O.
uint64
MappedResource
Indicates the type of memory mapped I/O. MappedResource defines whether memory or I/O is mapped, and for I/O, whether the mapping is to a memory or a port space. Memory mapped I/O values are as follows:
Other
Mapped memory
I/O mapped to memory space
I/O mapped to port space
uint16
CIM_DMA
The CIM_DMA class explained in Table 3-41 contains DMA information. A DMA channel allows certain types of data transfer between RAM and a device to bypass the microprocessor.
Identifies a part of the object's key value, the DMA channel number.
uint32
Availability
Indicates the availability of the DMA. Values for the Availability property are as follows:
Other
Unknown
Available
In use/not available
In use and available/shareable
uint16
CIM_RedundancyGroup
The CIM_RedundancyGroup class explained in Table 3-42 is a set of components that provide more instances of a critical component than are required for the system's operation. The extra components are used in case of critical component failure. For example, multiple power supplies allow a working power supply to take over when another power supply has failed.
Serves as the key for the redundancy group's instance in an enterprise environment.
string
RedundancyStatus
Provides information on the state of the redundancy group. Values for the RedundancyStatus property are as follows:
Unknown
Other
Fully redundant. Fully redundant means that all of the configured redundancy is still available.
Degraded redundancy. Degraded redundancy means that some failures have been experienced but some reduced amount of redundancy is still available.
Redundancy lost. Redundancy lost means that a sufficient number of failures have occurred so that no redundancy is available and the next failure experienced will cause overall failure.
uint16
CIM_ExtraCapacityGroup
The CIM_ExtraCapacityGroup class explained in Table 3-43 applies to systems that have more capability and components than are required for normal operation, for example, systems that have extra fans or power supplies.

MinNumberNeeded
Specifies the smallest number of elements that must be operational in order to have redundancy. For example, in an N+1 redundancy relationship, the MinNumberNeeded property should be set to N.

DELL_PSRedundancyGroup
The DELL_PSRedundancyGroup described in Table 3-44 is a Dell-specific extension of the CIM_PowerSupply class. The DELL_PSRedundancyGroup class defines what constitutes power supply redundancy in a system.

CIM_EnabledLogicalElement Group
The CIM_EnabledLogicalElementGroup class described in Table 3-46 extends the CIM_LogicalElementGroup class to abstract the concept of an element that is enabled or disabled, such as a LogicalDevice or ServiceAccessPoint.
The CIM_ServiceAccessPointGroup class described in Table 3-47 represents the ability to utilize or invoke a service. Access points indicate that a service is available to other entities for use.
The CIM_RemoteServiceAccessPointGroup class identified in Table 3-48 describes the accessing and addressing of information for a remote connection that is known to a "local" network element. This information is contained in the "local" network element since this is the context in which it is "remote". The relevance of the remote service access point and information on its use are described by subclassing or associating to the CIM_RemoteServiceAccessPointGroup class.
Describes accessing or addressing of information for a remote connection. This can be a host name, network address, and other similar information.
