Remote SAN Island Connectivity
The SANbox 6142 Intelligent Router supports inter-connecting remote SAN
islands (see Figure 2-2).
Figure 2-2 Remote SAN Island Connectivity
This configuration has the following additional requirements:
 At least one FC Port of SANbox 6142 connected to FC SAN.
 Accessibility between the iSCSI/ GE (GE identifies Gigabit Ethernet ports on
the router) Port IP addresses of remote router and iSCSI/GE port IP
addresses of local routers.
 Accessibility between the remote SANbox 6142 management port IP
address and local SANbox 6142 management port IP address.
When connecting SANs over long distances, it’s important to determine the
round-trip latencies between two router connections. You can discover these
round-trip latencies using the ping command in CLI. (See page A-25.)
Using this round-trip latency number, you can determine the window scaling factor
for GE (iSCSI) port, as described in Performance Tuning on page 3-3. By default,
window scaling is set to 1 (64K) TCP window size.
