The IPS modules or MPS-14/2 modules transparently map the command between the iSCSI virtual target
and the virtual Fibre Channel host (see

Routing SCSI from the IP host to the Fibre Channel storage device consists of the following main
actions:
•
•
•
FCP (the Fibre Channel equivalent of iSCSI) carries SCSI commands over a Fibre Channel SAN.

This section describes how to configure iSCSI on the Cisco MDS 9000 Family switches.

The iSCSI requests and responses are transported over an IP network between the hosts and the IPS
module or MPS-14/2 module.
The SCSI requests and responses are routed between the hosts on an IP network and the Fibre
Channel storage device (converting iSCSI to FCP and vice versa). The IPS module or MPS-14/2
module performs this conversion and routing.
The FCP requests or responses are transported between the IPS module or MPS-14/2 module and
the Fibre Channel storage devices.
