Eclipse™ 2640 SAN Router Administration and Configuration Manual
Example Configurations and Procedures
Example Configurations and Procedures
This section provides procedures to configure the SAN Router for
connecting remote SANs through iFCP. This section assumes that
you have SANvergence Manager software installed.
Figure 4-10 illustrates two SAN Routers connecting two FC disks
across a TCP/IP metropolitan area network (MAN) or wide area
network (WAN).
NOTE:
Although this example shows SAN Routers connected directly to
storage devices, SAN Routers can also connect through FC switches.

MAN/WAN Links
Since the WAN/MAN connection is a TCP-based iFCP link, TCP
automatically restransmits any dropped packets. This configuration
provides several benefits including:
• Very high performance including, data compression, FastWrite,
and support for large TCP window sizes.
• High availability and scalability through state change notification
(SCN), containment and separate mSNS, internet storage name
services, and servers per site. Since SCN messages are contained,
topology changes in the local site are not transmitted to all the
switches in the remote site.
