Looking for recommendations for a similar setup myself, so am bumping this rather than starting a new thread ...
I'm in the UK, and UPS units seem pretty reasonable just now, e.g. around £50 incl tax for an APC Back-UPS CS 350VA. A couple of questions for those with knowledge or experience please:
1. Although the example model above has 4 outlets, will 350VA be sufficient for 4 reasonably hungry (450-550w PSU) servers, or will it melt quickly? I suspect the latter, in which case, what is the minimum rating I should consider for such an installation?
2. In practice, how often could I expect to have to replace the battery in this unit (or similar)?
3. My installation suffers frequent short outages (possibly due to load shedding), but rarely anything more than around 5 minutes at most, so I don't need anything hardcore. Anything that will enable me to initiate graceful shutdown after 5-10 minutes' (or less if necessary) outage would be good. With this in mind, should I be considering anything radically different from the APC model mentioned above?
Thanks for reading, and for any input
