Configuring SmartExtend Step By Step
At least two NAS-3410s are required, one as an initiator, another as a target. SmartExtend

NAS functions.
The SmartExtend function is an optional feature which must be activated by a license key. Please
contact the vendor to obtain the license key.
All NAS-3410 can become SmartExtend targets. You do not have to activate the function.

SmartExtend target volume. A SmartExtend initiator will try
to connect to every target volume in the target volume list
when it starts up.
If network is not very stable, a SmartExtend target volume
might be disconnected occasionally. A SmartExtend initiator
will try to recover a broken connection every 5 minute. The
feature improves data availability even in a poor network.
