Zone management
The zone manager (SAS-2 compliant software) lets you configure and manage each zone. As shown
in Figure 13 (top), the zone manager can control a zone by using an end device with a SAS port
connected to one of the zoning expanders. The zone manager can also control a zone through a
sideband interface (such as Ethernet) on one or more zoning expanders (Figure 13 bottom).
