The I
P Storage Ser vices Modules (IPS-4, IPS-8), Multi-protocol Services Module (14/2), and the MDS
9216i switch provide IP hosts access to Fibre Channel storage devices. The IP h ost sends SCSI commands
encapsulated in iSCSI protocol da ta units (PDUs) to a C-Series IP port over a TCP/IP connection. At
this point, the SCSI commands are transferred from an I P network into a Fibre Channel network and
for
warded to the intended target. Figure 2 illustrates an IP Storage Servi ces Modules (IPS-4, IPS-8),
