I own a file server running Ubuntu Server 12.04 and am looking to get a UPS for it.
APC seems like the best brand but I could be swayed by an Eaton. It needs to be USB capeable and preferably have a pure sine wave output.
As far as functionality goes I require it to shutdown the server through USB when the battery runs down to a certain point and then restart the machine when AC power is resumed.
I will only be running the server and the modem/router off this UPS and therefore a 750W model should be more than adequate.
The problem is that the new APC Smart-UPS models use a proprietry connection technology (the SMX/SMT lines) which do not work with Ubuntu's APCUPSD Daemon.
That writes a lot of the new and less expensive APC UPS's out of the equation.
I'm looking at this older model rack mounted UPS from APC, but it's awful lot of money!
Can anyone recomend a quality UPS of any brand that will do what I've specified above?
