Or (accidentally) pull the wrong cord? :)Why all this concern about how long a disk (or SSD) drive can stay up after a power failure? Yep -- Murphy. And he's a bastard.It seems to me that anyone interested in maintaining an important database would have suitable backup power on their entire systems, including the disk drives, so they could coast over any power loss. I do not have any database that important, but my machine has an APC Smart-UPS that has 2 1/2 hours of backup time with relatively new batteries in it. It is so oversize because my previous computer used much more power than this one does. And if my power company has a brown out or black out of over 7 seconds, my natural gas fueled backup generator picks up the load very quickly. Am I overlooking something? |
