Figure 4 shows the supported cabling scheme for remote replication on EVA models with 4–port
controllers. On these models, each controller has redundant connections to both fabrics. Even-numbered
ports are c onnected to one fabric and odd-numbered ports are connected to the other fabric.

Figure 5 shows the supported cabling scheme for remote replication on arrays with controller software
version VCS 3.x. These models require the order in which ports are attached to a fabric to be reversed on
the two controllers. For example, if you attach the first port on one controller to the gray fabric, attach the
second por t on the other controller to the g ray fabric.
