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 that requires purchasing a license key.
You may enter the SmartWrite feature key using the Router Manager (see the
iSR6142 Router Manager User's Guide) or Command Line Interface (CLI) (see
the iSR6142 Router CLI User's Guide).
Qualified applications using SmartWrite include:
Server connected to Remote FC Storage array
Array Data Replication applications
EMC – Mirrorview™ - EMC
EMC – SAN Copy™
HDS / Hitachi – True Copy™ with Fabric connect
HP – CA for XP
All other Data replication applications like IBM Shadow Copy™, EMC - SRDF, etc.
should use the router’s FCIP mode.
Additional Server/Ports
iSR6142 supports mapping of up to 62 server/ports between two SANs. The
default configuration supports mapping 16 server/ports between SANs. For
example, you may map eight iSCSI initiators to FC SAN and map eight 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 that 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 the iSR6142 Router Manager User's Guide) or Command
Line Interface (CLI) (see the iSR6142 Router CLI User's Guide).
