2.2.5Single Host Connected to Four Controller Modules in a Loop Using Hubs

FIGURE 2-6shows an example of one host connected through fiber-optic cables to four StorEdge A3500FC controller modules in a loop using hubs.

Note –No other type of fibre channel device should share the same loop or hub connected to the A3500FC controller module.

Each controller that is connected to a hub must have a unique loop ID. Whenever you add a second controller to a hub, make sure that the loop ID of the controller being connected is different from the loop ID of any other controller currently connected to the same hub.

Refer to Section 2.3 “Setting the Loop ID” on page 2-13 for instructions on setting the loop ID of a controller.

Caution –Ensure that the controller module IDs are set so that each hub is connected to A and B controller canisters.
