# Class CIM_StorageRedundancyGroup
extends CIM_RedundancyGroup

A class derived from RedundancyGroup containing mass storage-related redundancy information. StorageRedundancy Groups are used to protect user data. They act on one or more underlying StorageExtents, associated via ExtentRedundancyComponent and produce one or more protected StorageExtents that are associated to the underlying StorageExtents via ProtectedExtentBasedOn or CompositeExtentBasedOn. StorageRedundancyGroups may overlap. However, the underlying StorageExtents within the overlap should not contain any check data. The use of this class is being deprecated in lieu of using the StorageRedundancySet class.

Description | string | A class derived from RedundancyGroup containing mass storage-related redundancy information. StorageRedundancy Groups are used to protect user data. They act on one or more underlying StorageExtents, associated via ExtentRedundancyComponent and produce one or more protected StorageExtents that are associated to the underlying StorageExtents via ProtectedExtentBasedOn or CompositeExtentBasedOn.

## Class Properties

### Local Class Properties

Name | Data Type | Default Value | Qualifiers
--- | --- | --- | ---
Name | Data Type | Value
IsConcatenated | boolean |
Deprecated | string | CIM_CompositeExtent.IsConcatenated
Description | string | True indicates that the data is concatenated across the various StorageExtents in the Group.
IsStriped | boolean |
Deprecated | string | CIM_CompositeExtent.ExtentStripeLength
Description | string | True indicates that the data is striped across the various StorageExtents in the Group.
StorageRedundancy | uint16 |
Deprecated | string | No value
Description | string | StorageRedundancy provides additional information on the state of the RedundancyGroup, beyond the RedundancyStatus property. Information like "Reconfig In Progress" (value =1) or "Redundancy Disabled" can be specified using this property.
ValueMap | string | 0, 1, 2, 3, 4, 5, 6, 7, 8
Values | string | No Additional Status, Reconfig In Progress, Data Lost, Not Currently Configured, Protected Rebuild, Redundancy Disabled, Unprotected Rebuild, Recalculating, Verifying
TypeOfAlgorithm | uint16 |
Deprecated | string | CIM_StorageRedundancySet.TypeOfAlgorithm
Description | string | The TypeOfAlgorithm specifies the algorithm used for data redundancy and reconstruction. For example, "P+Q" (value =5) or "P+S" (7) may be specified. The value of 0, is defined as "None" to indicate that data redundancy is not active. An inactive redundancy should only be instantiated if data striping or concatenation are active. These are indicated by the IsStriped or IsConcatentated boolean properties of this RedundancyGroup.
MappingStrings | string | MIF.DMTF|Redundancy Group|001.2
ValueMap | string | 0, 1, 2, 3, 4, 5, 6, 7
Values | string | None, Other, Unknown, Copy, XOR, P+Q, S, P+S
