ENERGY STAR Overview • Federal government product and building labeling program – Established in 1992 – Shared between EPA and DOE – Voluntary participation by private sector – Federal agencies required to buy EStar products • Label awarded for energy efficiency. – Top 25% of market • Also promote better practices. – Power management – Efficiency of buildings • Save money, protect environment, add value to products. • Influential brand recognized by over 80% of Americans
ENERGY STAR in the Data Center • Product specifications for – Servers: v2.0 under development – Storage: v1.0 by early Q4 – UPS: v1.0 effective 8/1/12 • Development starting soon on – Large Network Equipment – Data Center Cooling Equipment Labeled Products • Provide information to users to control energy costs. – Portfolio Manager (Buildings) – Product labeling – Power and Performance Datasheet Data Center Low-Carbon (Products) Building Metric – Low- carbon IT Program: “Top 12 Data IT Program Center Efficiency Strategies”
Typical ENERGY STAR Product Specification Development • Recruit participants for spec development/revision process – Manufacturers, retailers, utilities, industry orgs, interested individuals, etc. • Try to use international standards for test method – May deviate or develop own testing if necessary • Stakeholders provide market efficiency data – Used to set efficiency levels. • Drafting process – Issue draft, then ~1 month comment period. – All participants may comment, usually hold a stakeholder meeting to discuss. – We use comments to revise next draft. – Typically ~3 drafts. • Publish final document – New product category effective immediately. – Revisions effective 9 months later. • Total development time ~12 months. • Monitor market share of ENERGY STAR – Ideally starts at 25% for a new revision. – Increases over time. – If it becomes too large, launch revision of specification to bring levels back to 25%. – Revisions happen every 2 – 5+ years, depending on product/market. 5
ENERGY STAR Partners • Sign a partnership agreement. • Test products, adhere to labeling guidelines • More information online: http://www.energystar.gov/index.cfm?c=join.manuf_retail_agree 6
Why Should I Get Involved in ENERGY STAR? • Get your products labeled – Ensure that they can be purchased by federal agencies. • Gain national recognition – As energy and environmentally conscious business. – Use ES logo in promotional materials. • Widely recognized – Potential for ES awards such as Partner of the Year. • Provide information and guidance in development of specifications – Ensure that our efficiency levels, product definitions, scopes, and processes are appropriate. 7
Storage Specification Update 8
Review of ENERGY STAR Goals Identify products and configurations that provide superior energy efficiency Fairly and consistently represent energy Minimize efficiency benefits of testing/reporting valid product burden for ENERGY configurations to end STAR partners users and sales/fulfillment channels
History • Kick-off: April 2009 • Draft 1: April 2010 • Draft 2: October 2011 • Draft 3: June 2012 • Draft 4: August 2012 (TBD) • Final: November 2012 • Effective: Jan/Feb 2013 (3 months after final) • Great deal of support from SNIA, TGG • Input from EU, manufacturers, industry associations, government agencies. 10
Review of Storage Draft 3 • Product Scope • Power Supply Requirements • Product Family • Energy Efficient Feature Requirements • Information Reporting Requirements • Performance Data Measurement and Output Requirements • Testing / Test Method • Additional Topics 11
Broad View of Storage Products • SNIA Taxonomy • Many different approaches to storage • Differences in – Performance – Energy consumption – End-uses – Technology type – And more! 12
Draft 3 Scope Overview • Version 1.0 focuses on the following categories: – Online 2* – Online 3 – Online 4 * Note: Additionally, all systems must contain RAID controller with the storing product offering. Systems which utilize server based RAID controllers (JBODs) are excluded from the ENERGY STAR scope 13 “Table 4 –Online Classifications” taken from the SNIA Emerald ™ Power Efficiency Specification V1.0
Draft 3 Scope Subtleties • Scale-up vs. Scale-out • Inclusion of Block I/O capable NAS • Additional exclusions – NAS File I/O-only Storage Products – Blade Storage Products – JBODs – Object Storage Products 14
Power Supply Requirements • Levels consistent with CSCI Silver • PSU requirements only apply to PSUs that power primary equipment – Controllers and Drawers • EPA encourages the use of ENERGY STAR qualified products that can be used in conjunction with qualified storage products when possible 15
Workloads Recognized in Draft 3 • Transaction (IOPS/W) • Streaming (Mbps/W) • Capacity (GB/W) • Compromise based on real-world workloads • Intended to reasonably cover most use cases 16
Product Families in ENERGY STAR • Rather than test every configuration, ENERGY STAR defines product families • Test one or a few representative models/configs – Allows one or a few tests to represent many products/configurations • Reduce testing burden for highly configurable products 17
Common Product Family Attributes for Storage – Made by the same manufacturer – Be from the same model line or machine type – Utilize the same model of Storage Controller – Fall under the same SNIA taxonomy category – Controller(s) contain equal or greater amount of cache than the corresponding qualified configuration 18
Difficulty in Defining a Product Family • Challenge: • How do you define a representative model for storage when the products – Are hugely configurable/flexible? – Have very different energy efficiency profiles based on workload and hardware configuration? – Can incorporate newer components (HDDs, etc.) over their lifetime? 19
Defining a Family in Practice • Draft 3 proposal: – Optimal system testing: Test configurations optimized for single, specific workload • Choose Transaction and/or Streaming, can add a Capacity system. • Test a range of systems sizes, since energy efficiency varies with size. – System combinations: Allow for combinations of optimized systems to be labeled ENERGY STAR. – Storage media substitutions: Allow for reasonable HDD, SSD substitutions to be made as drive technology improves. 20
Defining a Family in Practice • System sizes tested: – Optimal: Manufacturer-defined optimal energy efficiency point. – Maximum: 15% larger in storage device count than optimal configuration – Minimum: 40% smaller in storage device count than optimal configuration • System sizes qualified: – Maximum: 5% larger – Minimum: 20% smaller – Everything between max and min – (Optional) Alternative Minimum: Beyond 20% smaller allowed with optional submission of additional physical data point(s) below the Minimum which: • Are within 10% of the Optimal Configuration performance (Work/Watt), • Applicable ONLY to Transaction or Streaming optimized configurations. 21
Optimal System Testing Points 22
Combinations Greater flexibility of configuration and delivery of qualified ENERGY STAR systems • System Combinations: – Combine optimal configurations using % allocation of Storage Media from testing – Applicable with all Optimization types (Transaction, Streaming, Capacity) • And Block-I/O portion of NAS system • Storage Media Substitutions: – Storage media performance changes rapidly – Avoid burden of system retesting – Limited to like storage media, and stated system performance must remain within 20% of original approved system 23
Energy Efficient Features • Make available at least Parity RAID • Revised COM approach 24
Recognized COM Features • The following COMs are currently recognized by EPA – Thin Provisioning – Data Deduplication – Compression – Delta Snapshots • The COMS listed above will be verified using the verification procedures found in the SNIA Emerald TM Power Efficiency Measurement Specification Version 1.0 (8/23/11) • Will accept additional COMS as verification procedures become available in the future. 25
COM Requirements • EPA proposes to require a certain number of recognized COMs be made available for purchase, with this number determined by the size of the system 26
Information Reporting Requirements • Active and Idle State Efficiency Disclosure Requirements • Power and Performance Datasheet (PPDS) • Data Measurement and Output Requirements • Test Method 27
Active and Idle State Efficiency Disclosure Requirements • EPA proposes to make data for all required fields public for Version 1.0 28
