Just to answer the questions asked:
The server room is not seperately AC cooled. The main rack is enclosed and fan blown from the bottom and the heat is sucked out from the top and we had are HVAC put an exhaust out of the room. These are the list of things all ready in the works.
A heat temp gauge that will email my cell on certain temperatures (from internally).
A web ping, 5min intervals, service to my cell, so if our website goes down, we know (Externally).
I installed a two hour fire/water prrof safe for intenal backups and data.
As for 24/7, heck no. We are out the door at 5 and try not to look back.
We are in Texas, so not really worried about earthquakes, maybe Tornados.
