Dell EMC ECS U2000 User Manual

The daisy-chain or ring topologies are not recommended for large installations. When
there are four or more ECS appliances, an aggregation switch is recommended. The
addition of an aggregation switch in a star topology can provide better fail over by
reducing split-brain issues.

U-Series or below the hare switch in a C-Series segment.
