Generator story:Capacity planning
Substation outside datacentre gives up the ghost.
UPS works flawlessly.
Generator comes on-line with no problem.
Electricity supplier comes to do emergency repair to substation - one phase completely burnt out - fair amount for work required...
Slight problem: generator has been sized to power the equipment in the datacentre, but for some reason, someone either forgot, or decided not to include powering the data-centre air-cooling/conditioning in the calculations. Ooops.
So, the loading bay airlock doors are opened wide, and mobile fans brought in to get outside airflow. Engineer monitoring hard-disk temperatures of the big-iron says we can let them go up to a certain temperature, but above that, the warranty no longer applies.
Decision was taken to void warranties - and luckily nothing happened immediately, and thankfully, there wasn't a rash of disk failures afterwards - but it had a lot of people sweating.
Biting the hand that feeds IT
