Question
An engineer is implementing a storage area network where an NPV is used. The engineer notices that the servers in a storage farm are experiencing heavy traffic contention. The engineer needs to migrate traffic from heavily loaded server interfaces to interfaces with less load. When the new links are deployed, the existing traffic is not rebalanced as expected. Which feature must be used to meet these requirements?

Explanation
In NPV mode, by default, a load-balancing algorithm assigns server interfaces to NPV core switch links upon initial login, but when new links are deployed, existing traffic is not automatically redistributed to achieve better load balance. Disruptive load balancing is a feature that forces reinitialization of the server interfaces to rebalance traffic across the available NPV external (uplink) interfaces. This enables the migration of traffic away from heavily loaded interfaces to less busy ones. Without disruptive load balancing enabled, traffic remains on the initial assigned uplink until manual intervention (such as manually flapping interfaces).
