Class CIM_StorageSetting
extends CIM_SettingData

StorageSetting is roughly equivalent to a Service Level Agreement (SLA) It defines the characteristics, qualities of service and goals when used in a CreateOrModifyElement FromStoragePool or CreateOrModifyStoragePool method in the StorageConfigurationService. It specifies a series of properties with Maximum and Minimum values that define the (inclusive) bounds that the object should maintain. Note that the setting is associated to a StorageVolume or LogicalDisk, using ElementSetting. The use of these properties differs depending on whether the StorageSetting instance is being used as a goal for a configuration operation or being used as a Service Level Agreement for a created Volume. In addition the properties fall into two categories: The QOS properties(PackageRedundancy, Data Redundancy, & NoSinglePointOfFailure) and the Detailed RAID properties(ExtentStripeLength, ParityLayout, and UserDataStripeDepth). In a Setting used as a goal, the QOS properties are required as a set; The Detailed RAID properties(if supported as indicated by the scoping StorageCapabilities instance) may be used optionally in any combination. The implementation MUST supply it's own best practice in the case where one or more supported RAID properties are not supplied. In this situation the use of StorageSettingWithHints can be useful to provide direction to the implementation. In a Setting used as a service agreement for a Volume, the QOS properties reflect the Service Level Agreement, with goal, min, & max. The actual current service level is exposed by corresponding values in StorageExtent. The Detailed RAID properties, by contrast, reflect specific values that reflect the RAID construction of the Volume. Only the primary values are meaningful; Min and Max are set to match. Certain StorageSetting instances may be classed as "Fixed", by using the "ChangeableType" property, indicating the setting is preset. Such settings are used when the possible setting variations are low enough to be instantiated in their entirety. The StorageCapabilities "CreateSetting" method MAY NOT be used to return settings that are not changeable. Other StorageSetting instances are created using the "CreateSetting" method. If the capabilities specifies ranges, then the setting can be used by a client to narrow the range to particular values within the range. In other words, the capabilities MAY be broad, but the related setting MUST be as capable or less capable, that is more narrowly defined, before it is used to create or modify resources. These created StorageSetting instances MUST have their "ChangeableType" property = 1, "Changeable - Transient". GeneratedSettings MAY not remain after the restart or reset of the implementation. They may be deleted by implementation at any time. A reasonable minimal time to retain the generated transient settings is five minutes, although there is no minimal retention time.

ChangeableTypeuint16
DescriptionstringEnumeration indicating the type of setting. "Fixed - Not Changeable" settings are primordial. These setting are defined at the implementor of the class. "Changeable - Transient" is the type of setting produced by the "CreateSetting" method. A client can subsequently request that the implementation persist the generated and potentially modified setting indefinately. Only a "Changeable - Transient" setting SHALL be converted to a "Changeable = Persistent" setting; the setting SHALL NOT be changed back.

ExtentStripeLengthuint16
DescriptionstringExtentStripeLength 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'. When used in a goal setting instance, ExtentStripeLength is the optimal desired value. The bounds (max and min) for Stripe Length are defined using the properties ExtentStripeLengthMax and ExtentStripeLengthMin. ExtentStripeLength MUST be set to NULL if the scoping StorageCapablities indicates that it is not supported in this context. ExtentStripeLength can be used in conjunction with CreateOrModifyElementFromELements to explicitly configure storage. An example would be RAID 0+1 with mirroring two stripe sets, each set being three wide. In this case CreateOrModifyElementFromElements would be passed a goal setting with DataRedundancy = 2 and ExtentStripeLength = 3. The size of the InElements array would be 6 and would contain the StorageExtents to be used to construct the StorageElement as a RAID 0+1. ExtentStripeLengthMin and ExtentStripeLengthMax are meaningless and wouldbe set to NULL. If the property is supported, and is part of StorageSettingWithHints it MAY be set to NULL. If used it will constrain the effects of Hint selections. When used in a Setting instance associated to a Volume, this property indicates the specific value that the Volume was created with, and ExtentStripeLengthMin and ExtentStripeLengthMax will be set to the same specific value.
