In Japan it is common for production servers to be turned off at night, the incentive to do this is that the Japanese insurance industry offers much cheaper cover for companies that turn off power after dark. This poses the question whether we should all be acting in such a manner and turning servers and appliances off over night.

Text of Article

I recently met with Fujitsu Siemens Computer about green data initiatives, based on what the joint venture calls IT with a sense of responsibility. The underlying hook to the narrative is Japanese/German engineering excellence (not a bad peg, I am sure you’d agree).

Bernhard Brandwitte, director of product marketing for FSC and perhaps more importantly in the context of behavioural change an excellent story-teller, told me something that really rocked me on my heels: in Japan its common to turn production servers off at night. Yup- apparently the Japanese insurance industry tries to avoid fires in plants at night by offering much cheaper cover for companies that power down after dark.

What does that mean in practice? A much more coherent backup and recovery strategy for one. A commitment to not 24/7, not follow the Sun, not have uptime for its own sake.

I have been thinking about this issue for a while, but it was a tweet from Chris Dalby this morning that pulled the trigger:

yellowpark is going green. I’m turning my server off each night

Chris is someone I deeply respect. Another cool thing is that he won’t shop at supermarkets- all his shopping is packaging free, from a local farm shop. When he tweets a delicious lunch menu you know the vegetables were never wrapped in plastic. That is a pretty good metaphor for Chris: He is very real, very passionate, and focuses on local issues. He is all about change from the grassroots.

Chris’ commitment to server-off computing is cool because he is an expert in technologies such as Windows Small Business Server, which he sells into small and medium-sized businesses. I wonder if he could set up a service helping SMBs become more green, given his bona fides?

All I know is that much as we should all turn off our appliances at night, and our cellphone chargers, so we should ask - do we really need that server on all night?
