Example 3
This example maps three subsets of Fibre Channel LUN targets to three iSCSI virtual targets. Two iSCSI
targets have one LUN and the third iSCSI target has two LUNs (see

Presenting iSCSI Hosts as Virtual Fibre Channel Hosts

The IPS module or MPS-14/2 module connects to the Fibre Channel storage devices on behalf of the
iSCSI host to send commands and transfer data to and from the storage devices. These modules use a
virtual Fibre Channel N port to access the Fibre Channel storage devices on behalf of the iSCSI host.
iSCSI hosts are identified by either iSCSI qualified name (IQN) or IP address.

Initiator Identification

iSCSI hosts can be identified by the IPS module or MPS-14/2 module using the following:

iSCSI qualified name (IQN)
An iSCSI initiator is identified based on the iSCSI node name it provides in the iSCSI login. This
mode can be useful if an iSCSI host has multiple IP addresses and you want to provide the same
service independent of the IP address used by the host. An initiator with multiple IP addresses
(multiple network interface cards—NICs) has one virtual N port on each IPS port to which it logs in.
IP address
An iSCSI initiator is identified based on the IP address of the iSCSI host. This mode is useful if an
iSCSI host has multiple IP addresses and you want to provide different service-based on the IP
address used by the host. It is also easier to get the IP address of a host compared to getting the iSCSI
