MSFT_SMPool class
Represents a storage pool. A storage pool is a logical grouping of physical disks that may be used to create virtual disks.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.
Windows Server 2012 R2 and Windows Server 2012: This class does not inherit from MSFT_SMStorageObject which is new for Windows Server 2016.

-
Qualifiers: MinValue (0), MaxValue (100), ModelCorrespondence ("CIM_StoragePool.RemainingManagedSpace"), PUnit ("percent"), Units ("Percentage")
A low space warning is generated when the remaining space is reduced to this percentage of the total storage capacity.
Name
-
