SnapMirror technology of NetApp FAS

Snapmirror access control

Allowing FAS node2 (Dst.) to mirror the FAS node1 (Src.) could be set in the two method below:

1. options snapmirror.access host=node2
2. options snapmirror.access legacy
   wrfile /etc/snapmirror.allow

   [ctrl-c]

Snapmirror Firewall setting

Snapmirror Async:

Source system listens on TCP port 10566.
When multi-pathed, the destination system listens on TCP port 10565.

Snapmirror Sync/Semi-sync:

Source system listens on TCP ports 10566 and 10569.
Destination system listens on TCP ports 10565, 10567 and 10568.

Need to be checked out:

“Multi-pathed destination system listens on TCP port 10565.” doesn’t seem to be used only in multi-pathed destination.
