In a cluster of Array appliances(h/w load balancer), one appliance becomes Master for a particular VIP and handles all traffic related to that VIP. All others stay in Backup status. If the appliance containing the Master fails, one of the appliances in Backup status changes to Master status. Note: If multiple VIPs are configured, then Masters can be configured so that they are distributed among the appliances in the cluster, providing additional performance.
