Intersystem link for host traffic

If you use the intersystem link for host traffic, ensure that you have sufficient bandwidth to support all sources of load.

Scenario: The hosts in a local clustered system can read and write to the volumes in a remote system

In this scenario, the hosts in the local system also exchange heartbeats with the hosts that are in the remote system. Because the intersystem link is being used for multiple purposes, you must have sufficient bandwidth to support the following sources of load:

Local host to remote volume I/O traffic or remote host to local volume I/O traffic.
Local-host-to-remote-host heartbeat traffic.
