Class CIM_RedundancySet
extends CIM_SystemSpecificCollection

A class derived from SystemSpecificCollection that is a special collection of ManagedElements. This collection indicates that the aggregated elements together provide redundancy, or that redundancy is provided via sparing. All elements collected in a RedundancySet SHOULD be instantiations of the same object class.

LoadBalanceAlgorithmuint162
DescriptionstringThe current load balance algorithm. Least Blocks, Least IO, and Address Region are used in storage device path redundancy drivers to optimize load balancing by routing requests to a path with the least queued blocks or IO requests, or based on locality of reference. 'Product Specific' indicates that the algorithm is optimized for a particular type of product. Information about that product SHOULD be provided in an associated CIM_Product instance.

MaxNumberSupporteduint32
DescriptionstringMaxNumberSupported indicates the largest number of elements that can participate in the RedundancySet. A value of 0 indicates there is no limit on the number of elements.
MinNumberNeededuint32
DescriptionstringMinNumberNeeded indicates the smallest number of elements that MUST be operational in order to function. For example, in an N+1 redundancy relationship, the MinNumberNeeded property is set equal to N. In a 'LimitedSparing' environment, this property is meaningless and SHOULD be set to zero.

DescriptionstringWhen LoadBalanceAlgorithm is Other, this property describes the algorithm.

RedundancyStatusuint16
DescriptionstringRedundancyStatus provides information on the state of the RedundancyGroup. 'Fully Redundant' (value=2) means that all of the configured redundancy is still available; 'Degraded Redundancy' (3) means that some configured elements are degraded, missing or failed but that the number of elements in the set is still greater than the minimum required ('MinNumberNeeded'); 'Redundancy Lost' (4) means that sufficient configured elements are missing or failed that no redundancy is available and the next failure experienced will cause overall failure. 'Overall Failure' (5) means that there has been an overall failure of the RedundancySet.

VendorIdentifyingInfostring
DescriptionstringVendorIdentifyingInfo captures the vendor identifying data for the RedundancySet. One example is the product name for a cluster.

DescriptionstringWhen the corresponding array entry in TypeOfSet[] is 'Other', this entry provides a string describing the type of set.

ArrayTypestringIndexed
DescriptionstringTypeOfSet provides information on the type of redundancy. N+1 (=2) indicates all members are active, are unaware and function independent of one another. However, there exist at least one extra member to achieve functionality. 'Sparing' is implied (i.e. each member can be a spare for the other(s). An example of N+1 is a system that has 2 power supplies, but needs only 1 power supply to functioning properly. N+1 is a special case of N+M redundancy where M=1. A value of N+1 (=2) shall be used for N+M redundancy. - Load Balanced (=3) indicates all members are active. However, there functionality is not independent of each other. Their functioning is determined by some sort of load balancing algrothim (implemented in hardware and/or software). 'Sparing' is implied (i.e. each member can be a spare for the other(s). - Sparing (=4) indicates that all members are active and are aware of each others. However, their functionality is independent until failover. Each member can be a spare for the other(s). - Limited Sparing (=5) indicates that all members are active, and they may or may not be aware of each and they are not spares for each other. Instead, their redundancy is indicated by the IsSpare relationship.
