Dell EMC SmartFabric OS10 User Guide Release 10.5.0

ETS provides customized bandwidth allocation to 802.1p classes of traffic. Assign different amounts of bandwidth to Ethernet, FCoE, or iSCSI traffic classes 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 the required bandwidth, configure bandwidth and queue scheduling for each priority group. To prioritize low-latency storage and server-cluster traffic, allocate more bandwidth to a priority group. To rate-limit best-effort LAN traffic, allocate less bandwidth to a different priority group.
