distance max on veritas cluster VVR

Dear Support

I want to implement a VCS cluster replication between 2 nodes_storages.

What is the max distance for heartbeat connection?

Can I use FC for heartbeat connection?

Regards.

    3km is definately possible - I have seen clusters doing 50km.  So as long as you have 2 reliable links, this should be fine, but there is also the option to increase the gab timeout by specifying in the /etc/gabtab file.

    For VVR there is no limit, so it is only the VCS heartbeats you need to be concerned about.

    Radio would not be recommended but what is more important is that the latency is less than 500ms.
