It'll take shrewd planning, an understanding of a new set of metrics and a little legerdemain to find ways to reduce the power consumption of storage gear and still provide the capacity the company wants. Storage vendors are well aware of this new exigency, preparing new products or enhancing existing ones to help storage managers stem the tide of power consumption.
But just slapping the word "green" on a product does little to ensure that it will provide some electrical relief. Data reduction will also play a key role in any power-conserving efforts. You'll probably have to adjust some of your internal data management processes to ensure that you're not running up excessive power bills by spinning too many disks.
You also need to determine what metrics you'll need to accurately measure power consumption in your shop and the results of your efforts. If this hasn't happened to you yet, it will. Someone in your organization will put together storage and electrical use, and you'll be on the hot seat.
This E-Guide will get you started or, if you're already in the midst of a power-pruning project, help you further along your way.

TABLE OF CONTENTS FOR THE GREEN STORAGE ESSENTIAL GUIDE
- Storage hogs power: For all the talk about green storage, the power-saving initiative remains more of a server issue than a disk storage issue. But that may change due to the rapidly increasing rate of data growth and the continuing energy pinch.
- Tips to save power: Power and cooling issues have become a hot (pun intended) topic for IT-related equipment, especially video monitors, servers, networks and storage systems. The reasons for having an interest in power and cooling can be tied to green initiatives, budget concerns (rising energy prices), or the need to support the growth of your applications and data requirements with an existing power and cooling capability.
- Power saving options: Just as the power crunch, which began in the server industry, has become the future for storage, the approaches to fixing the problem may originate there as well. According to some experts, research on the server side into methods to reduce the number of power conversions required to get energy from a wall socket into a computer could drastically reduce power consumption in servers and storage if the methods were widely adopted.
- Seeking more metrics: Everyone's trying to measure power usage in data centers. So it's clear why nonprofit organizations such as The Green Grid—a consortium of IT firms promoting energy efficiency through user-centric metrics, standards development and best practices—are trying to measure data center power usage. So why do storage-specific metrics remain elusive?
