Architecture Overview
The switch benefits from an intelligent, multi-layer switching, fully distributed and passive backplane 
architectural design that provides redundancy of critical hardware and software elements for a continuous 
(non-stop) traffic processing in any network conditions without a single point of failure. Switch process-
ing scheme includes a non-blocking store-and-forward crossbar design switching fabric with a distributed 
processing. The architecture supports a true redundancy of management and the switch fabric. The 
OmniSwitch 7000 new and highly intelligent design encompasses advanced distributed architecture 
including state-of-the-art ASICs. 
The architecture is designed around three major ASICs named the Catalina, the Coronado and the 
Nantucket.
