Redundancy and Latency
When planning a fabric, consider how to create redundant paths and minimize
latency. Initiators and targets experience the least amount of latency when
connected to the same I/O blade. For example, connecting initiator and target “A”
ports together on one I/O blade and initiator and target “B” ports on another I/O
blade, as shown in Figure 3-1, creates redundant paths and minimizes latency.
