The following configuration example illustrates the basic principles in the PowerMaxOS iSCSI Target Model. This configuration is an example of a basic port binding configuration where the host initiator would have a single connection and session with the iSCSI IP Interface on the PowerMax. The IP Interface is associated with a single port and attached to a single target on the director SE instance. This configuration is sometimes called a 1/1/1 configuration.
X The 1/1/1 configuration is a commonly used configuration by PowerMax iSCSI customers. Even though a PowerMax iSCSI target can make use of multiple IP interfaces on different ports (on the same director), many customers prefer to the more simplistic approach of having a single target and IP interface per SE port on the array. In order to enable multipathing, multiple iSCSI targets are placed into the port group of the masking view created for the host that has multipathing software (PowerPath/Multipath IO) installed.
A multipathing enabled masking view for the above configuration would include the following components:
Note: In the above configuration example, the IP interfaces for the two targets use unique VLANs (VLAN 82 and VLAN 83). In many production implementations, only a single VLAN will be used for the entire iSCSI SAN. The use of a single VLAN for an iSCSI environment is shown in the next implementation example.
