NameData TypeValue
CompressionIdleIntervaldatetime
DescriptionstringNumber of days data on a volume must be idle before the Automated Storage Tiering subsystem starts compressing the data. Valid interval must be in number of days between 1 and 365.

Writebooleantrue
CompressionRateuint16
DescriptionstringIndicates the rate at which the Automated Storage Tiering subsystem compresses the data. The smaller the number, the higher the rate of compression.
MaxValuesint6410
MinValuesint641
Writebooleantrue
DeleteOnEmptyStorageTierbooleanfalse
DescriptionstringIf true and empty storage tiers are allowed, the storage tier will be deleted when the last component object is removed from the storage tier. If empty storage tiers are not allowed, the storage tier will be deleted automatically when the last component object is removed from the storage tier.
Writebooleantrue
Dynamicbooleanfalse
DescriptionstringIf true any new objects added to the system that have a similar performance characteristics (and QoS) to this tier become part of this tier automatically. If false, the new objects needs to be added to this tier manually.
Writebooleantrue
InitialStateuint162
DescriptionstringThis property indicates whether the storage tier is actively being used or not.

Writebooleantrue
Percentageuint16
DescriptionstringA value between 0 to 100 to indicate the maximum percentage of the underlying capacity that can be used for storage tiering activities. For example, a value of 80 indicates no more than 80 percent of the storage tier can be used for automated tiering. The remaining 20 percent of the underlying storage is set aside for elements that do not participate in automated storage tiering.
Writebooleantrue
RelativePerformanceOrderGoaluint16
DescriptionstringA number starting from 0 to indicate the relative performance characteristics of the storage tier. The smaller the number, the higher the performance characteristics.

RelativePerformanceOrderMaxuint16
DescriptionstringIndicates the maxmimum value for RelativePerformanceOrder that this storage tier can have. The maximum value for RelativePerformanceOrder that this storage tier can have, which represents the lowest level of performance.

RelativePerformanceOrderMinuint16
DescriptionstringIndicates the minimum value for RelativePerformanceOrder that this storage tier can have. The minimum value for RelativePerformanceOrder that this storage tier can have, which represents the highest level of performance.

StorageObjectTypeuint16
DescriptionstringThis property indicates the type of storage objects comprising a storage tier. ComponentsOfStoragePool: Storage tier is comprised of ConcreteComponents of a StoragePool. ElementsOfStoragePool: Storage tier is comprised of elements, e.g. volumes, allocated from a StoragePool.

StorageTierCharacteristicsuint16[]
DescriptionstringIndicates the storage tier charateristics. Performance generally relates to the underlying technology, for example, Solid State versus Fibre Channel drives. QoS refers to the Quality of Service, for example, RAID protected versus unprotected.
