fabric-attached devices communicate, the FL_Port automatically translates between private and public addresses. The FL_Port translative mode supports up to 32 fabric-attached devices (one is reserved for the fabric) appearing on each local loop of private devices, subject to the limit of 126 devices on a loop (the total of private and fabric-attached devices). Private devices are registered to the Simple Name Server (SNS), so the fabric-attached devices can query SNS for their addresses and initiate communication. NOTE: Loops may contain any combination of public or private loop devices. The following fabric topology samples show several different conceptual topology models. Each installation has a unique topology that is determined by the characteristics of the connected devices and your performance objectives. The simplest fabric consists of a single-switch topology as shown in Figure 2-1.

The switch connections are shown as they would be in a physical installation. Functionally, the switch becomes a fabric with every device connected to every other device by the fabric.
