Explanation
The Aruba CX 6400 switch is a modular switch that supports high-performance and high-density Ethernet switching for campus and data center networks. One of the features that distinguishes the Aruba CX 6400 switch from most typical campus switches is virtual output queueing (VOQ). VOQ is a technique that implements large ingress packet buffers on each port to prevent head-of- line blocking and packet loss due to congestion. VOQ allows each port to have multiple queues for different output ports and prioritize packets based on their destination and QoS class. VOQ enables the Aruba CX 6400 switch to achieve high throughput and low latency for various traffic types and scenarios.
