We have a generator backup that powers the entire building. Our Datacenter draws about a total of 6600 watts (I have no idea if that is a lot or not).
My problem is that we recently had a ice storm that knocked out our city power and it was that one time that the generator did NOT pick up, therefore our everything went down. After fixing everything, I was instructed to get pricing on a UPS solution that would keep us up and running for a long period of time, management was talking 3 to 4 hours.
I do not agree with the 3 to 4 hours of "up-time", but figured I would get some pricing starting at one hour and going up to 4.
Is there a general "rule of thumb" when it comes to up-time?
Are there better ways to cover redundancy in case of generator failure the long periods of up time?
I am worried about heat when we start talking about long periods of run time without our data center air conditioner running.
Where do I start with this?
Any guidenace would be helpfull....
