Prior to the upgrades all clusters and services within the clusters (CAS arrays, DAG, etc.) were able to interact with each other. By utilizing VLAN and QoS on the switch we have been able to limit down the amount of multicast traffic and broadcasts between networks which dramatically improved network responsiveness within each cluster. By limiting the outside “noise” we have seen a 130% improvement of log shipment between DAG nodes across clusters and an 80% improvement of CAS related traffic. All in all these network changes directly improve the customer experience by providing a faster handling and response of requests to mailboxes.
