WHO'S USING 100G?

The CloudEngine 12800 series consists of three chassis-based platforms with four-, eight- and 12-I/O slots, and two slots for main processing units. On the rear side of the switch are slots for six fabric modules -- five primary, plus one for redundancy.

The line is based on a non-blocking CLOS fabric architecture, and features front-to-rear ventilation to improve heat dissipation. The high-end CloudEngine 12812 will support up to 96 100G Ethernet ports, 288 40G Ethernet ports and 1,152 10G Ethernet ports.
