You can create a NetMRI failover pair using two NetMRI appliances, in which one acts as the primary appliance and the other as the secondary appliance. A failover pair provides a backup or redundant operational mode between the primary and secondary appliances so you can greatly reduce service downtime when one of them is out of service. You can configure two Operation Center (OC) appliances, collector appliances, or standalone appliances to form a failover pair.
