Example 1 with TrafficStatistics

use of com.emc.fapiclient.ws.TrafficStatistics in project coprhd-controller by CoprHD.

the class RecoverPointUtils method getPreferredRPAForNewCG.

/**
 * Returns the preferred RPA number to use as the primary RPA for a new
 * consistency group. The preferred RPA is determined by examining the
 * current throughput for all of the passed in cluster's RPAs and selecting
 * the RPA that is currently handling the least amount of throughput.
 *
 * @param impl - the established connection to an appliance
 * @param clusterUID - corresponding to the site that we are trying to determine the preferred RPA for.
 * @return RpaUID - object with the preferred RPA number
 * @throws FunctionalAPIActionFailedException_Exception
 * @throws FunctionalAPIInternalError_Exception
