Figuring out your organization’s power needs can be overwhelming. You can’t just plug devices into some surge protectors and wait for your utilities bill, just as you can no longer hook up some servers and storage into a closet and turn down the thermostat. Now you have to worry about your servers’ power and density profiles, target the direction of your cooling, and pinpoint ways you can save energy—often by using virtualization or other green measures—without compromising your network, among other things.
