As today’s trends drive the demand for increasing bandwidth in data centers, Ethernet switches must respond with the ability to use the available bandwidth effectively. Congestion management is particularly important, along with advanced quality-of-service (QoS) features that enable the switches to maximize throughput for priority traffic.


This technology backgrounder profiles the capabilities of the Fujitsu MB8AA3021 Ethernet switch chip with a focus on data center requirements. To explain why these capabilities are vital, the paper opens with an overview of data center trends.
