This solution is available via failover, which will be implemented in the next DSS release.
This technology will be available for iSCSI only.
The automation is done using a "Heartbeat" cable that is connected to the two servers.
If you want to use it you need to use virtual IP address. If primary DSS goes down then the second DSS goes up and takes over IP address from the primary machine.
Next DSS release should be available in couple of days.
