 * of initiator port WWN and storage port WWN keyed by zone-key, where zone-key
 * is the concatenation of the initiator port WWN and the storage port WWN.
 * <p>
 * Note that the map returned contains only the zones that were selected for use by ViPR. In the case of duplicate zones between an
 * initiator-port pair, ViPR applies a selection criteria to choose one. See {@link #selectZonesForInitiatorsAndPorts}

 * entries in the map, one for each initiator/port pairs.
