Starting with the Sun StorageTek Common Array Manager (CAM) 6.4.1, support for Access Configuration (also known as “zoning”) of the Sun StorageTek J4000 array series (J4200, J4400, and J4500) has been added. Through CAM Access Configuration, you can assign each host (and each initiator in a host) its own storage resources. Accomplished on a per host initiator (HBA) port, per hard-disk level basis, Access Configuration offers the following benefits: storage resource segregation, controlled resource sharing, protection, and topology control.
Sun Storage J4500 Array with Zoned Storage shows a color-coded example of how you might divide the array storage among multiple hosts using zoning. Four connected hosts (on the left), each has exclusive ownership of a specific set of disks allocated to their zone (as indicated by the matching color disks shown in the open cover view of the array on the right). Disks may be zoned in a single array or across cascaded arrays.
Figure 3-1 Sun Storage J4500 Array with Zoned Storage
The dual SAS fabric design of the J4500 array (SAS A and B) is seen in CAM as two separate SAS domains. These domains are zoned separately. In a multipath situation, where you want two initiators to have access to the same disks for failover, each domain, or path, must be configured identically in CAM. CAM provides zoning templates to aid the user in setting up the appropriate configurations, as well as the ability to import and export user-defined templates.
Note - For multipath failover support with zoned disks, you will need to perform Access Configuration in CAM first, and then enable the appropriate multipath driver for your operating system. For information on enabling a multipath driver, refer to Chapter 4, SAS Multipathing.
Two Hosts With Zoned Disks in CAM shows a zoned configuration of the J4500 array's 48 disks with host 1 owning the even number disks, and host 2 owning the odd numbered disks.

 | Caution - In a multipath failover configuration, granting multiple hosts access to the same disks is not supported. Only single host, multi-initiator access is allowed. |
