The second major difference compared to VIPRION, is the introduction of centralized/redundant SX410/SX1610 system controllers. The pictures above show the two redundant system controllers that are standard with the VELOS 4RU CX410 & the 16RU VELOS CX1610 chassis:

For the CX410 chassis, the system controllers are responsible for providing non-blocking connections and layer 2 switching between the 8 slots within the system. The system controllers are star-wired with multiple connections to each slot. There are currently two different generations of line cards supported: the BX110 and BX520. Each BX110 blade has one 100Gb backplane connection to each system controller (200Gb total). The picture below shows the backplane interconnections of a fully populated 8 slot CX410 chassis with 8 BX110 blades installed.
