The data center I was at was one of those. They lost power, the UPS took over like it was supposed to. The generator started and took over like it was supposed to. When it was time to switch back to mains power; *pop* the main breaker popped and power was lost. AFAIK, this was the first time the generator was tested under load. They also had the power company come out to switch meters. The meter *exploded* and sent a guy to the hospital (he was OK). Again, all servers in the center went down hard. Another data center I've used switches to the generator *every* Friday. Which is good. Bad part is they don't have enough UPS capacity for the entire data center - you have to provide your own or just accept that your servers will reboot every Friday at the same time. -- Jacob Coby --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "symfony users" group.
