The following figure shows a simple example of zoning.

		Figure 7:	Simple Zoning Example
1.5.2	Creating SAS Zones	You create SAS zones by first creating zone groups that include hosts or storage devices
		that share common access privileges, and zone sets that connect the zone groups
		together. Use the SDM utility to create zones. The SDM-GUI utility provides zoning
		wizards to create zone groups and zone sets automatically. You also can create zone
		groups and zone sets manually by using the SDM utility.

The following rules apply to zone groups and zone sets:

„ Only phys on the edge of the ZPSDS can be grouped into administrator-defined zone groups. Phys that interconnect zoning expanders are automatically placed into Zone Group 1.

„ An administrator defines zone group permissions. This procedure allows end devices attached to, or downstream of, the zoned phy to communicate with one another.

„ Zoning limits a host's access to only the targets downstream of zoned phys in which its zone phy is granted zoning permission to access. A host may access all logical unit numbers (LUNs) behind the SAS phy, and it does not restrict access to individual storage LUNs.

„ You may create up to 248 zone groups within a single zone set.

„ SAS phys within a zone group cannot automatically access each other, but you may grant them access privileges.

„ You may grant a zone group permission to access multiple zone groups, if required. „ A zone group may be a member of more than one zone set.

„ A phy may be a member of only one zone group per zone set.
