Seems Like a Good Choice for UPS

Last weekend we had a power-outage in the office (while no-one was here). Not sure how long it lasted, but it's raised a few questions around here, and prompted a search into getting a UPS.

Our primary, mission-critical machines are in a data center, but it seems that some of the development machines sitting under various desks in the office are referenced more regularly than we thought, and having them down is noticeable to people other than ourselves. And yes, we do care about people other than ourselves. Getting the *prefect* UPS isn't really a priority, just want to quickly poke around and get something that will do the job.

Didn't take much looking around to put together an idea of what we need. Stumbled into a nice UPS overview which provided good information both on UPS on Linux as well as how to calculate needs. The power-usage section estimated each machine taking around 60W.

Will be putting three or four boxes on the UPS, and want 30+ minutes to avoid short power interruptions and have time to shut down if the power doesn't come back. Decided to narrow my range to a UPS that will offer 300W for ~30 minutes.

I looked at APC, TrippLite, Belkin and Best Power, ended up choosing the APC Smart-UPS 1000VA. APC appeared to be a good choice. Good history, highly recommended and provides auto-shutdown software for Linux OS.

The poor life of a UPS, it's one of those things you put in place and then forget about. Most likely will protect us from numerous outages without us ever noticing. Guess it can only look forward to the time 2 or 3 years down the road when it's time to replace the battery.
