Chapter 52 Configuring IP Storage
Services Modules
• FCIP—FCIP transports Fibre Channel frames transparently over an IP network between two Cisco
MDS 9000 Family switches or other FCIP standards-compliant devices. Figure 52-1 shows how the
IPS module is used in different FCIP scenarios.

• iSCSI—The IPS module provides IP hosts access to Fibre Channel storage devices. The IP host
sends SCSI commands encapsulated in iSCSI protocol data units (PDUs) to a Cisco MDS 9000
Family switch IPS port over a TCP/IP connection. At this point, the commands are routed from an
IP network into a Fibre Channel network and forwarded to the intended target. Figure 52-2 depicts
the iSCSI scenarios in which the IPS module is used.
