Good point, Brian.
You want UPS battery backup if for no other reason than to ensure an orderly shutdown and buffer flush. In my configuration there are two UPS units -- one feeds the NAS units, the network switch and firewall, the server is on the other. Enough battery capacity to run things for an hour. An orderly shutdown of the arrays and server starts after 30 minutes of power outage. The observatory PC has two SSDs -- the images from the night (or day) get flushed to the server while I am closing. Nothing is retained there -- it all moves to the network.
