Sun Microsystems McDATA Eclipse 1620 Release Notes page 4

Overview
The McDATA Eclipse 1620 SAN Router is a single unit FRU (Field Replaceable Unit),
which provides support for the following standard protocols:
iSCSI - provides the iSCSI initiator with access to the fibre channel targets
iFCP - provides remote data replication and IP SAN routing
E_Port - enables connection to an existing fabric
When a McDATA 1620 Router is connected to a fabric, it extends the communication
between devices beyond a single fabric. Since iFCP and iSCSI are IP based forms of
communication, there is no distance limitation on the Fibre Channel port.
With the support of multiple vendors fabric across the IP, the McDATA Eclipse 1620
essentially bridges the communication between fabrics from different vendors,
which is not permited by the FC switches.
