Any other performance issues or errors?  Do you have to manually re-initiate the connection?

We do. I don't see any network issues and performance seems fine...Any way of monitoring this better that you can think of? (Free? This place is cheap lol)

When the host runs a scan and losses its connection, are there any errors logged in the host's event\system log or the SAN's log?

If there are no useful messages or errors on the SAN or the switch that sits between the SAN and servers, then the next step would be to contact Dell and see if they have any known issues or recommended firmware updates for the SAN.

Ended up not being the SAN but Co-Pilot is the best option.
