Communicating With A Partner Host; Cisco To Cisco; Cisco To Linux; C H A P T E R 5 Asynchronous Replication - Cisco C3124SA Manual

The first replication that is performed on a pairing is always a FULL replication. Subsequent replications
Note
reflect the delta, except where an "Update Partner" operation is performed. In that case, the immediate
next replication would become a FULL replication.

Communicating with a Partner Host

To perform replication successfully, there must be a way for communicating between the local LUN and
the remote replication site to establish that the client (local Cisco Array) is allowed to invoke commands
on the server (remote replication site).
The Cisco Array uses the standard remote shell facility, ssh, leveraging on password-less access after
putting its public key to the proper location at the remote replication site.
For LUNs, Cisco supports open-target Async Replication. It can duplicate to the following platforms:
