Green Storage - The Big Picture
SW Worth

Green Storage is about more than just reducing operational expenses (OpEx) for energy and cooling.  If your data center were somehow able to shut down all of its Storage devices when they are not being used, you could certainly save a lot on your energy bills.  However, your organization would still have to bear the capital expenses (CapEx) not only for the Storage equipment, but also for the power-hungry equipment needed to support the IT gear in your data center, including those mysterious boxes with strange names (UPS, PDU, CRAC, CFD, and more).  This stuff really matters if you don't pay attention, those pesky server-geeks will end up running the data center, hogging all the credit for virtualizing and consolidating their servers, and blaming your Storage gear for ruining the planet, or at least breaking the IT budget.  This SNIA Tutorial helps you understand the Big Picture affecting your IT CapEx, OpEx, and engineering decisions to minimize your TCO and environmental impacts.  Get a quick primer on the key differences between power and energy, the economics of energy supply, including carbon taxes and how cap-and-trade will affect your IT planning.  Understand why environmental regulations in Europe and Asia directly affect the IT equipment you buy, and even how you can dispose of your worn-out gear.  Even if you successfully avoided topics such as environmental chemistry, thermodynamics, and heat transfer in school, you'll get a quick and relatively painless refresher on why these issues matter to your IT decisions.   We'll leverage your knowledge to drill into best practices for data centers, with practical advice for lowering your energy overhead to less than 25% of your IT energy usage.  (It's probably close to 100% overhead right now!)  Examples include conversion losses, AC and DC power choices, and power supply and fan efficiency improvements.  By the end of this session you'll know why it's a really good idea to make friends with your facilities manager.  You'll even get some great suggestions for negotiating reductions of your energy bills from your friendly local utility.    All of this doesn't mean that we won't have time to introduce Storage-specific 'green' topics, including proper use of various RAID levels, data reduction (snapshots, compression, and de-duplication), thin provisioning, and other useful techniques.  However, later "Green Storage" Tutorials will offer more detailed drill-downs on these topics.

Learning Objectives

  • Get a "Big Picture" overview of what "Green" means to IT, and specifically for Storage. 
  • Gain a good understanding of how the power and cooling issues in your datacenter will affect your IT decisions. 
  • Understand why 'OpEx' (Operating expenses) can outweigh 'CapEx' (Capital expense) in TCO models, and how 'Green' factors increasingly influence OpEx.

Green Storage Products: Efficiency with ENERGY STAR & Beyond
Erik Riedel

This tutorial will cover storage-specific topics related to energy-efficiency and outline the current state of the industry. We will discuss a range of technologies that are currently considered "green storage" and the components of modern storage systems that impact energy consumption. We will discuss potential metrics for measuring, managing and designing for power in storage systems. We will also outline ongoing efforts by the EPA ENERGY STAR® program and in the SNIA Green Storage Technical Work Group (TWG) to standardize metrics for measuring storage systems.

Learning Objectives

  • Understand the storage-specific aspects of 'green' (especially energy and power) for storage components and aggregated products (e.g. arrays, controllers, appliances)
  • Outline considerations in how to measure and model storage energy and power; identify technologies that might reduce the ongoing energy costs of reliably maintaining data
  • Overview ongoing industry efforts to establish metrics and standards for more energy efficient storage

Green Storage Technologies, CAPEX and OPEX
Alan Yoder

The best green storage technologies don't just affect power consumption--they can also significantly reduce your acquisition costs. This tutorial takes a dollar-and-cents view of the green technology and process areas, helping you prioritize your acquisition planning and attention. We cover green storage technologies, the importance of efficient facilities, and recent developments in ENERGY STAR regulation of the storage sector.

Learning Objectives

  • Learn how capacity optimization and storage efficiency can help you save money and reduce your power footprint. 
  • Learn how efficient facilities can save your company significant amounts of money. 
  • Find out what the EPA is up to.  Is there an ENERGY STAR program for storage?
