			ModelCorrespondence	string	CIM_StorageCapabilities.DataRedundancyMax, CIM_StorageCapabilities.DataRedundancyDefault
DeltaReservationDefault	uint16
			Description	string	Delta reservation is a number between 1 (1%) and a 100 (100%) that specifies how much space should be reserved by default in a replica for caching changes. For a complete copy this would be 100%, but it can be lower in some implementations. This parameter sets the default value, while DeletaReservationMax and DeltReservationMin set the upper and lower bounds.
			MaxValue	sint64	100
			MinValue	sint64	0
			ModelCorrespondence	string	CIM_StorageCapabilities.DeltaReservationMax, CIM_StorageCapabilities.DeltaReservationMin
			PUnit	string	percent
			Units	string	Percentage
DeltaReservationMax	uint16
			Description	string	DeltaReservatioMax is a number between 1 (1%) and a 100 (100%) that specifies the maximum amount of space reserved in a replica for caching changes. For a complete copy this would be 100%, but it can be lower in some implementations. This parameter sets the upper limit, while DeltaReservationMin sets the lower limit.
			MaxValue	sint64	100

			ModelCorrespondence	string	CIM_StorageCapabilities.DeltaReservationMin, CIM_StorageCapabilities.DeltaReservationDefault
			PUnit	string	percent
			Units	string	Percentage
DeltaReservationMin	uint16
			Description	string	DeltaReservationMin is a number between 1 (1%) and a 100 (100%) that specifies the minimum amount of space that should be reserved in a replica for caching changes. For a complete copy this would be 100%, but it can be lower in some implementations. This parameter sets the lower limit, while DeltaReservationMax sets the upper limit.

			ValueMap	string	0, 1, 2, 3, 4, 5, 6, 7, 8
			Values	string	Unknown, Reserved, Any Type, StorageVolume, StorageExtent, StoragePool, StorageConfigurationService, LogicalDisk, StorageTier

			Experimental	boolean	true
			ValueMap	string	0, 1, 2
			Values	string	Unknown, Not Supported, Supported
ExtentStripeLengthDefault	uint16
			Description	string	Extent Stripe Length describes the number of underlying StorageExtents across which data is striped in the common striping-based storage organizations. This is also known as the number of 'members' or 'columns'. A NULL value for ExtentStripeLengthDefault indicates that the system does not support configuration of storage by specifying Stripe Length. If Extent Stripe Length is supported, and this Capabilities instance is associated with a pool that was created with a range of QOS then ExtentStripeLengthDefault represents the default value. Other available values(such as min, max, and discrete values) can be determined by using the 'GetSupportedStripeLengths' and 'GetSupportedStripeLengthRange' methods. If Extent Stripe Length is supported and the pool was created with a single specific QOS, representing a Raid group, set, or rank, then this property represents the current/fixed value for the pool, and Extent Stripe Length is not supported in subsequent creation of elements from this pool. Consequently, the 'GetSupportedStripeLength' methods cannot be used, and in a StorageSetting instance used as a goal when creating or modifying a child element of the pool, ExtentStripeLengthGoal, ExtentStripeLengthMin, and ExtentStripeLengthMax MUST be set to NULL.
			MinValue	sint64	1
NoSinglePointOfFailure	boolean
			Description	string	Indicates whether or not the associated element supports no single point of failure. Values are: FALSE = does not support no single point of failure, and TRUE = supports no single point of failure.
			ModelCorrespondence	string	CIM_StorageCapabilities.NoSinglePointOfFailureDefault
NoSinglePointOfFailureDefault	boolean
			Description	string	Indicates the default value for the NoSinglePointOfFailure property.
			ModelCorrespondence	string	CIM_StorageCapabilities.NoSinglePointOfFailure
PackageRedundancyDefault	uint16
			Description	string	PackageRedundancyDefault describes the default number of redundant packages that will be used. For example, in the storage domain, package redundancy describes how many disk spindles can fail without data loss including, at most, one spare. An example would be RAID5 with a spare disk which would have a PackageRedundancy of 2. Possible values are 0 to n. The bounds for redundancy are specified using the properties, PackageRedundancyMax and PackageRedundancyMin.
			ModelCorrespondence	string	CIM_StorageCapabilities.PackageRedundancyMin, CIM_StorageCapabilities.PackageRedundancyMax
PackageRedundancyMax	uint16
			Description	string	PackageRedundancyMax describes the maximum number of redundant packages that can be used. For example, in the storage domain, package redundancy describes how many disk spindles can fail without data loss including, at most, one spare. An example would be RAID5 with a spare disk which would have a PackageRedundancy of 2. Possible values are 0 to n. The default redundancy is specified using PackageRedundancyDefault, while the maximum is defined by PackageRedundancyMax.
			ModelCorrespondence	string	CIM_StorageCapabilities.PackageRedundancyMin, CIM_StorageCapabilities.PackageRedundancyDefault
PackageRedundancyMin	uint16
			Description	string	PackageRedundancyMin describes the minimum number of redundant packages that can be used. For example, in the storage domain, package redundancy describes how many disk spindles can fail without data loss including, at most, one spare. An example would be RAID5 with a spare disk which would have a PackageRedundancy of 2. Possible values are 0 to n. The default redundancy is specified using PackageRedundancyDefault, while the minimum is defined by PackageRedundancyMin.
			ModelCorrespondence	string	CIM_StorageCapabilities.PackageRedundancyMax, CIM_StorageCapabilities.PackageRedundancyDefault
ParityLayoutDefault	uint16
			Description	string	ParityLayout specifies whether a parity-based storage organization is using rotated or non-rotated parity. If this capabilities instance is associated with a pool that was created with a range of QOS then ParityLayoutDefault represents the default value. Other available values can be determined by using the 'GetSupportedParityLayouts' method. If the pool was created with a single specific QOS, representing a Raid group, set, or rank, then this property represents the current/fixed value for the pool, and ParityLayout is not supported in subsequent creation of elements from this pool. Consequently, the 'GetSupportedParityLayouts' method cannot be used, and the ParityLayoutGoal property in StorageSetting instances used in child element operations on this pool MUST be set to NULL. A NULL value for ParityLayoutDefault indicates that the system does not support configuration of storage by specifying ParityLayout.
			ValueMap	string	2, 3
			Values	string	Non-Rotated Parity, Rotated Parity
UserDataStripeDepthDefault	uint64
			Description	string	User Data Stripe Depth describes the number of bytes forming a strip in common striping-based storage organizations. The strip is defined as the size of the portion of a stripe that lies on one extent. Thus, ExtentStripeLength * UserDataStripeDepth will yield the size of one stripe of user data. A NULL value for UserDataStripeDepthDefault indicates that the system does not support configuration of storage by specifying Stripe Depth. If User Data Stripe Depth is supported, and this Capabilities instance is associated with a pool that was created with a range of QOS then UserDataStripeDepthDefault represents the default value. Other available values(such as min, max, and discrete values) can be determined by using the 'GetSupportedStripeDepths' and 'GetSupportedStripeDepthRange' methods. If User Data Stripe Depth is supported and the pool was created with a single specific QOS, representing a Raid group, set, or rank, then this property represents the current/fixed value for the pool, and User Data Stripe Depth is not supported in subsequent creation of elements from this pool. Consequently, the 'GetSupportedStripeDepth' methods cannot be used, and in a StorageSetting instance used as a goal when creating or modifying a child element of the pool, UserDataStripeDepthGoal, UserDataStripeDepthMin, and UserDataStripeDepthMax MUST be set to NULL.
