Earth Day 2010

In honor of Earth Day the guru is looking for ways to store data in an efficient and safe way. One focus is on reducing the power consumption of running equipment such as NAS devices (consolidating multiple running machines into one data store). The other is to determine what data can really be stored offline (e.g. on disks that are powered down and only used when needed), similar to turning off the lights when they are not needed. Finally (and most effective) figure out what does not need to be stored at all!
Happy lights out to you.
