So when asking clients about the most important things in their server room you will consistently hear answers about the speed and power of their network, or the latest loaded server they have. Perhaps they will even talk about the great things they’ve done with virtualization.
However, the one thing that people never seem to mention is their UPS power. The funny thing is without your UPS’, nothing would be running in the first place. Funnily enough, this is the one place people seem to consistently neglect in my experience.
You see UPS batteries should be replaced at least every 3 years otherwise they tend to get old and not perform as well as you’d expect them to. Instead you see people leaving in batteries for over 5 years with no replacement. At this point the batteries provide no backup power and they’re all but useless.
So the next time you are thinking about keeping your server room up to snuff, please make sure that your UPS batteries are replaced on a regular basis before they expire.
