1.5.3 Configuring SAS Zones The following figure shows a sample configuration with three hosts and five JBODs.
Figure 8: Configuration for Zoning Example
Host 1 belongs to a local work group and accesses JBOD 1 as its primary resource. But
Host 1 also accesses JBOD 2, JBOD 3, and JBOD 4, as a backup resource.
Host 2 is a backup server, and has JBOD 2, JBOD 3, and JBOD 4 as its primary resource,
but also accesses JBOD 1.
Host 3 is a web server, and has exclusive access to JBOD 5, but also accesses JBOD 2,
JBOD 3, and JBOD 4 for backup.
Because Host 1 and Host 2 have the same JBOD access requirements, you can define
them as a single zone group. You can define JBOD 2, JBOD 3, and JBOD 4 as a zone
group because they are always used together as a backup resource.
