# Class CIM_TargetPortGroup
extends CIM_SystemSpecificCollection

TargetPortGroup aggregates the ProtocolEndpoints representing a group of target ports in a storage server. The ProtocolEndpoints may be a subclass of CIM_ProtocolEndpoint as appropriate for the type of target port implemented by the storage server. The target ports are aggregated because they have the same affinity for an associated storage processor for failover and the same accessibility state to storage resources in a given StorageResourceLoadGroup. The TargetPortGroup may have either a fixed affinity for a storage processor within the server or an affinity that changes during failover from one storage processors to another. TargetPortGroup has a instance of the StorageProcessorAffinity association to each instance of CIM_ComputerSystem representing a storage processor that may host the TargetPortGroup in either a healthy or failover state. Each instance of TargetPortGroup in a storage server is also associated to each instance of StorageResourceLoadGroup in the server by the AsymmetricAccessibility class. There is an instance of CIM_HostedCollection associating the StorageResourceLoadGroup with the top-level CIM_ComputerSystem that aggregates the storage processor ComputerSystem instances.
