Client Signal Latency on Aggregation Card
4-Port 1-Gbps/2-Gbps FC Aggregation Cards
The 4-port 1-Gbps/2-Gbps FC aggregation card adds latency to FC traffic. The amount of latency
depends on how traffic is configured on the node. Table 4-12 shows the FC latency values for different
configurations of the 4-port 1-Gbps/2-Gbps FC aggregation card.
