 Provides failover and failback between two gigabit ethernet links.
 Allows data compression. This is very useful when data round-trip latencies
between two routers exceed more than 50 ms or long distance link rate is
equal or less than 4500 Mbits/sec (DS-3 line rate)
SmartWrite is an optional feature which requires the purchase of a license key.
You may enter the SmartWrite feature key using the SANsurfer Router Manager
(see page 7-19) or Command Line Interface (CLI) (see page A-41).

Additional Server/Ports
SANbox 6142 supports mapping of up to 62 Server/Ports between two SANs. The
default configuration allows the mapping of 16 server/ports between SANs. For
example, you may map 8 iSCSI initiators to FC SAN and map 8 FC devices from
one FC SAN to another FC SAN. If your network requires more mappings, you
can add a feature key to support additional mappings in 23 server/port increments
as follows:
 16 Server/Port mappings - the default configuration.
 39 Server/Port mappings - includes the default 16 plus one “23 server/port
license”.
 62 Server/Port mappings - includes the default 16 plus two “23 server/port
licenses”.
Additional Server/Ports is an optional feature which requires purchasing a license
key. You may purchase up to two feature keys.
You can enter the Additional Server/Ports feature key using the SANsurfer Router
Manager (see page 7-19) or Command Line Interface (CLI) (see page A-41).
