Assign different amounts of bandwidth to traffic classes (Ethernet, FCoE, or iSCSI) that require different bandwidth, latency, and best-effort treatment during network congestion. ETS divides traffic into different priority groups using their 802.1p priority value. To ensure that each traffic class is correctly prioritized and receives required bandwidth, configure bandwidth and queue scheduling for each priority group. You can allocate more bandwidth to a priority group to prioritize low-latency storage and server-cluster traffic. Allocate less bandwidth to a different priority group to rate-limit best-effort LAN traffic. Converged data center services 651
