| Name | Data Type | Default Value | Qualifiers |
| Name | Data Type | Value |
| InstanceID | string | |
| Description | string | Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. In order 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 creating/defining the InstanceID, or is a registered ID that is assigned to the business entity by a recognized global authority (This 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 re-used to identify different underlying (real-world) elements. If the above 'preferred' algorithm is not used, the defining entity MUST assure that the resultant InstanceID is not re-used across any InstanceIDs produced by this or other providers for this instance's NameSpace.
For DMTF defined instances, the 'preferred' algorithm MUST be used with the <OrgID> set to 'CIM'. |
| Key | boolean | true |
| Override | string | InstanceID |
| PoolID | string | |
| Description | string | A unique name in the context of the System that identifies this pool. |
| MaxLen | uint32 | 256 |
| Required | boolean | true |
| Primordial | boolean | false |
| Description | string | If true, "Primordial" indicates that this StoragePool is the base from which storage capacity is drawn and returned in the activity of storage management. Being primordial means that this StoragePool 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 StoragePools. If false, "Primordial" indicated that the StoragePool, a concrete Storage Pool, is subject to storage services functions. This distinction is important because higher-level StoragePools may be assembled using the Component or AllocatedFromStoragePool associations. Although the higher-level abstractions can be created and deleted, the most basic, (i.e. primordial), hardware-based StoragePools 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. |
| RemainingManagedSpace | uint64 | |
| Description | string | The remaining usable capacity after the allocation of StorageVolumes, LogicalDisks, or child Storage Pools. This property is maintained here to provide efficient access to this information. However, note that it is possible to compute RemainingManagedSpace as (TotalManagedSpace minus the sum of SpaceConsumed from all of the AllocatedFromStoragePool references from this StoragePool). Note that SpaceConsumed remains useful to determine the amount of capacity consumed by a particular allocated element. |
| ModelCorrespondence | string | CIM_StoragePool.TotalManagedSpace, CIM_AllocatedFromStoragePool.SpaceConsumed |
| Required | boolean | true |
| Units | string | Bytes |
| TotalManagedSpace | uint64 | |
| Description | string | The total amount of capacity usable for the allocation of StorageVolumes, LogicalDisks, or child Storage Pools.
For primordial Storage Pools, this capacity reflects the usable capacity of Disk Drives or LUNs, for example, to the owning storage device or application. For example, in storage array, a primordial Storage Pool's TotalManagedSpace does not include metadata such as the disk label area and absolute disk drive capacity lost in disk formatting.
For concrete Storage Pools, the same applies, but the metadata not included in TotalManagedSpace is consumed in virtualization like RAID and concatenation. Concrete Storage Pool may also be simple reserve of capacity. In such a case, no capacity may be lost in formation of the Storage Pool.
Conceptually TotalManagedSpace is the sum of all storage known via AssociatedComponentExtent associations to underlying StorageExtents. However, note some of these underlying storage may not be modeled by the instrumentation. |
| ModelCorrespondence | string | CIM_StoragePool.RemainingManagedSpace |
| Units | string | Bytes |
| Name | Data Type | Value |
| Description | string | This method can be used to retrieve a list of available Extents that may be used in the creation or modification of a StoragePool, StorageVolume, or LogicalDisk. The GetAvailableExtents method MUST return the Extents from the set of Component Extents of the Pool on which the method is being invoked. The returned Extents are available at the time the method returns. There is no guarantee that the same Extents will be available later. This method MUST return the Extents that are not being used as supporting capacity for any other Pools, Volumes, or LogicalDisks that have been allocated from this Pool. The Extent returned MUST be a component Extent of the Pool or subdivisions of a component Extent, the subdivisions themselves represented as Extents. |
