Managing High-Density Ethernet

With a 100 Gbps fabric configuration, the overall data rate for the ES2 4G LM with the ES2-S1 10GE IOA is 3.4 Gbps for large packets. With a 120 Gbps or a 320 Gbps fabric configuration, the overall data rate for the ES2 4G LM with the ES2-S1 10GE IOA is 3.9 Gbps for large packets. In all configurations, the line module becomes highly oversubscribed because of the available wire rate on the IOA. When paired with the ES2 4G LM, the data rate of the ES2-S1 10GE IOA is bandwidth limited with larger frames, and the packet rate is limited with smaller frames.

Currently, flow control using MAC pause frames is disabled on the ES2-S1 10GE IOA. The IOA does not transmit or receive pause frames.
