Managing High-Density Ethernet

With a 100 Gbps fabric configuration, the overall data rate for the ES2 4G LM with ES2-S1

GE-8 IOAs is 3.3 Gbps. With a 120 Gbps fabric configuration or a 320 Gbps fabric

configuration, the overall data rate for the ES2 4G LM with ES2-S1 GE-8 IOAs is 3.8 Gbps.

In both configurations, the line module becomes highly oversubscribed because of the

IOA available wire rate. When paired with the ES2 4G LM, the data rate of the ES2-S1

GE-8 IOA is bandwidth limited with larger frames, and the packet rate is limited with

smaller frames.

NOTE: The overall data rate of the ES2-S1 GE-8 IOA is 0.1 Gbps less than other IOAs

that pair with the ES2 4G LM because of fair bandwidth allocation across the eight

ports.

Currently, flow control using MAC pause frames is disabled on the ES2-S1 GE-8 IOA. The

IOA does not transmit or receive pause frames.
