How many 400GE ports can be supported by a single board on the next-generation flagship...

The CloudEngine S16700 is Huawei's flagship core switch for large-scale enterprise campuses. It features an orthogonal Clos architecture with massive per-slot bandwidth (up to 14.4 Tbps). To support the evolution to ultra-high-speed backbones, the S16700 supports a high-density 400GE line card that provides 18 ports per board. When fully populated (8 slots), the S16700-8 chassis can support up to 144x400GE ports.
