Is a generator and UPS the ultimate solution?
No, it’s a good solution if you’re prepared to either close down your data centre or take a risk when it come to maintenance time. Both a generator and a UPS have to be taken off-line for maintenance. A solution for a 24/7 data centre must include redundant UPS and generators to allow maintenance to be carried out whilst remaining protected. An additional benefit is that in the unlikely event of failure of a unit the spare unit(s) will take up the load.
