Segmenting Private Loops
Stealth-3 Loop Switching Mode allows you to segment a private loop of devices that
do not yet support public loops into interconnected multiple loops—each with its
own 200 MBytes (full duplex) bandwidth. As shown in Figure 1-2, these multiple-
loop topologies allow you to isolate one or more devices on a switch port.
Switches running in Stealth-3 Mode also support cascaded switches (in a star
configuration) and “switch-attached” (N_Port) single-AL_PA devices (such as
RAIDs) that perform fabric login. For more information, see CHAPTER 5 on page
27 or APPENDIX C on page 57.
Figure 1-2. With the Vixel 9000 Series Switch, devices can migrate from a single
loop topology to a multiple loop topology
