Mixing Switch-Attached and Loop Devices
Stealth-3 Loop Switching Mode allows you to mix private loop devices with
“switch-attached” (N_Port) single-AL_PA devices (such as RAIDs) that perform
fabric login. This flexible topology improves the performance of host-to-storage
interconnection by providing dedicated bandwidth and eliminating loop arbitration
delays. Hubs and other 1-Gigabit speed devices can be connected to switch ports
that are running at 1-Gigabit speed.
