ElementName A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information.

Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following preferred algorithm:

<OrgID> : <LocalID>

Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, <OrgID> must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between <OrgID> and <LocalID> . <LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If the above preferred algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance. For DMTF-defined instances, the preferred algorithm must be used with the <OrgID>set to CIM.

MinNumberNeeded 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.

RedundancyStatus provides information on the state of the RedundancyGroup.

Possible values are:

• 0 = Unknown
• 1 = DMTF Reserved
• 2 = Fully Redundant — Indicates that all of the configured redundancy is still available
• 3 = Degraded Redundancy — Indicates 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);
• 4 = Redundancy Lost — Indicates that sufficient configured elements are missing or failed that no redundancy is available and the next failure experienced will cause overall failure.
• 5 = Overall Failure — Indicates that there has been an overall failure of the RedundancySet.

TypeOfSet 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.

Possible values are:

• 0 = Unknown
• 1 = Other
• 2 = N+1
• 3 = Load Balanced — Indicates all members are active. However, there functionality is not independent of each other. Their functioning is determined by some sort of load balancing algorithm (implemented in hardware and/or software). Sparing is implied (i.e. each member can be a spare for the other(s).
• 4 = Sparing — 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).
• 5 = Limited Sparing — 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.
• .. = DMTF Reserved
• 0x8000.. = Vendor Reserved
