CIM_ResourcePool class

  • Artigo

A ResourcePool is a logical entity (with associated controls) provided by the host system for the purpose of allocation and assignment of resources. A given ResourcePool may be used to allocate resources of a specific type. Hierarchies of ResourcePools may be created to provide administrative control over allocations. In the cases where resources are subdivided, multiple resource pools may exist (e.g. nodal boundaries in NUMA-like systems). In systems that support over commitment, pools represent the reservable capacity, not an upper bound or limit on the maximum amount that can be allocated. Admission control during power on may detect and prevent systems from powering due to resource exhaustion. For example, over commitment on a ResourcePool with ResourceType=Memory would require that sufficient space be available in some backing-store, that may be managed through a storage ResourcePool.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Members

The CIM_ResourcePool class has these types of members:

Properties

The CIM_ResourcePool class has these properties.

AllocationUnits

Data type: string

Access type: Read-only

This property specifies the units of allocation used by the Reservation and Limit properties. For example, when ResourceType=Processor, AllocationUnits may be set to MegaHertz. When ResourceType=Memory, AllocationUnits may be set to MegaBytes The value of this property shall be a legal value of the Programmatic Units qualifier as defined in Appendix C.1 of DSP0004 V2.4 or later.

Capacity

Data type: uint64

Access type: Read-only

This property represents the maximum amount (in units of AllocationUnits) of reservations that the ResourcePool can support.

Caption

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64)

The Caption property is a short textual description (one- line string) of the object.

This property is inherited from CIM_ManagedElement.

Description

Data type: string

Access type: Read-only

Contains a textual description of the object.

This property is inherited from CIM_ManagedElement.

ElementName

Data type: string

Access type: Read-only

Contains a user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information.

This property is inherited from CIM_ManagedElement.

HealthState

Data type: uint16

Access type: Read-only

Indicates the current health of the element. This attribute expresses the health of this element but not necessarily that of its sub-components.

This property is inherited from CIM_ManagedSystemElement.

The following values have been defined:

Unknown (0)

The implementation cannot report on HealthState at this time.

OK (5)

The element is fully functional and is operating within normal operational parameters and without error.

Degraded/Warning (10)

The element is in working order and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element might not be operating at optimal performance or it might be reporting recoverable errors

Minor failure (15)

All functionality is available but some might be degraded.

Major failure (20)

The element is failing. It is possible that some or all of the functionality of this component is degraded or not working.

Critical failure (25)

The element is non-functional and recovery might not be possible.

Non-recoverable error (30)

The element has completely failed, and recovery is not possible. All functionality provided by this element has been lost.

DMTF Reserved

DMTF has reserved the unused portion of the continuum for additional HealthStates in the future.

InstallDate

Data type: datetime

Access type: Read-only

Qualifiers: MappingStrings ("MIF.DMTF|ComponentID|001.5")

Indicates when the object was installed. The lack of a value does not indicate that the object is not installed.

This property is inherited from CIM_ManagedSystemElement.

InstanceID

Data type: string

Access type: Read-only

Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following "preferred" algorithm: <OrgID>:<LocalID> Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, <OrgID> must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between <OrgID> and <LocalID>. <LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If the above "preferred" algorithm is not used, the defining entity must ensure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance. For DMTF-defined instances, the "preferred" algorithm must be used with the <OrgID> set to CIM.

Name

Data type: string

Access type: Read-only

Qualifiers: MaxLen (1024)

The Name property defines the label by which the object is known. When subclassed, the Name property can be overridden to be a Key property.

This property is inherited from CIM_ManagedSystemElement.

OperationalStatus

Data type: uint16 array

Access type: Read-only

Qualifiers: ArrayType ("Indexed"), ModelCorrespondence ("CIM_ManagedSystemElement.StatusDescriptions")

Contains indicators of the current status of the element. The first value of OperationalStatus should contain the primary status for the element.

Note

OperationalStatus replaces the deprecated Status property. Due to the widespread use of the existing Status property in management applications, Microsoft strongly recommends that providers or instrumentation provide both the Status and OperationalStatus properties. When instrumented, Status (because it is single-valued) should also provide the primary status of the element.

This property is inherited from CIM_ManagedSystemElement.

The following values have been defined:

Unknown (0)

Indicates the implementation cannot report on OperationalStatus at this time.

Other (1)

Indicates an undefined state.

OK (2)

Indicates full functionality without errors.

Degraded (3)

Indicates the element is working and all functionality is provided. However, the element is not working to the best of its abilities. For example, the element might not be operating at optimal performance or it might be reporting recoverable errors

Stressed (4)

Indicates that the element is functioning, but needs attention. Overload and overheated are examples of Stressed states.

Predictive Failure (5)

Indicates that an element is functioning nominally but predicting a failure in the near future.

Error (6)

Indicates that an error has occurred.

Non-Recoverable Error (7)

A non-recoverable error has occurred.

Starting (8)

The job is starting.

Stopping (9)

The job is stopping.

Stopped (10)

The element has been intentionally stopped.

In Service (11)

Indicates the element is being configured, maintained, cleaned, or otherwise administered.

No Contact (12)

Indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it.

Lost Communication (13)

Indicates that the job is known to exist and has been contacted successfully in the past, but is currently unreachable.

Aborted (14)

Indicates the job stopped in an unexpected way. The state and configuration of the job might need to be updated.

Dormant (15)

Indicates that the job is inactive.

Supporting Entity in Error (16)

Indicates that an element on which this job depends is in error. This element may be OK but is unable to function because of the state of a dependent element. An example is a network service or endpoint that cannot function due to lower-layer networking problems.

Completed (17)

Indicates that the job has completed its operation. This value should be combined with either OK, ErrorError, or Degraded so that a client can tell if the complete operation Completed with OK (passed), Completed with Error (failed), or Completed with Degraded (the operation finished, but it did not complete OK or did not report an error).

Power Mode (18)

"Power Mode" indicates that the element has additional power model information contained in the associated PowerManagementService association.

DMTF Reserved

DMTF has reserved this portion of the range for additional OperationalStatus values in the future.

Vendor Reserved

Microsoft has reserved the unused portion of the range for additional OperationalStatus values in the future.

OtherResourceType

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_ResourcePool.ResourceType")

A string that describes the resource type when a well defined value is not available and ResourceType is set to 0 for Other.

PoolID

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_ResourceAllocationSettingData.PoolId")

An opaque identifier for the pool. This property is used to provide correlation across save and restore of configuration data to underlying persistent storage.

Primordial

Data type: boolean

Access type: Read-only

If true, "Primordial" indicates that this ResourcePool is a base from which resources are drawn and returned in the activity of resource management. Being primordial means that this ResourcePool shall not be created or deleted by consumers of this model. However, other actions, modeled or not, may affect the characteristics or size of primordial ResourcePools. If false, "Primordial" indicates that the ResourcePool, a concrete Resource Pool, is subject to resource allocation services functions. This distinction is important because higher-level ResourcePools may be assembled using the Component or ElementAllocatedFromPool associations. Although the higher-level abstractions can be created and deleted, the most basic, (i.e. primordial), hardware-based ResourcePools cannot. They are physically realized as part of the System, or are actually managed by some other System and imported as if they were physically realized.

Reserved

Data type: uint64

Access type: Read-only

This property represents the current reservations (in units of AllocationUnits) spread across all active allocations from this pool. In a hierarchical configuration, this represents the sum of all descendant ResourcePool current reservations.

ResourceSubType

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_ResourcePool.ResourceType")

A string describing an implementation specific sub-type for this pool. For example, this may be used to distinguish different models of the same resource type.

ResourceType

Data type: uint16

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_ResourcePool.OtherResourceType", "CIM_ResourcePool.ResourceSubType")

The type of resource this ResourcePool may allocate.

Qualifiers: Deprecated ("CIM_ManagedSystemElement.OperationalStatus"), MaxLen (10)

Contains a string indicating the primary status of the object.

Note

This property is deprecated and replaced by the OperationalStatus property. If you choose to use the Status property for backward compatibility it should be secondary to the OperationalStatus property.

This property is inherited from CIM_ManagedSystemElement.
