- 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%
- f 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
- Provide information to users to control
energy costs.
– Portfolio Manager (Buildings) – Product labeling – Power and Performance Datasheet (Products) – Low-carbon IT Program: “Top 12 Data Center Efficiency Strategies” Data Center Building Metric Labeled Products Low-Carbon IT Program
SLIDE 5
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.

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
SLIDE 12
Broad View of Storage Products
- SNIA Taxonomy
- Many different
approaches to storage
- Differences in
– Performance – Energy consumption – End-uses – Technology type – And more!
12
SLIDE 13
Draft 3 Scope Overview
- Version 1.0
focuses on the following categories:
– Online 2* – Online 3 – Online 4
13
“Table 4 –Online Classifications” taken from the SNIA Emerald™ Power Efficiency Specification V1.0
* 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
SLIDE 14
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
SLIDE 15
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
SLIDE 16
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
SLIDE 17
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
SLIDE 18
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
- f cache than the corresponding qualified
configuration
18
SLIDE 19
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
SLIDE 20
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
- ptimized systems to be labeled ENERGY STAR.
– Storage media substitutions: Allow for reasonable HDD, SSD substitutions to be made as drive technology improves.
20
SLIDE 21
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
- ptional 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
SLIDE 22
Optimal System Testing Points
22
SLIDE 23
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
SLIDE 24
Energy Efficient Features
- Make available at least Parity RAID
- Revised COM approach
24
SLIDE 25
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 EmeraldTM Power Efficiency Measurement Specification Version 1.0 (8/23/11)
- Will accept additional COMS as verification
procedures become available in the future.
25
SLIDE 26
COM Requirements
- EPA proposes to require a certain number
- f recognized COMs be made available for
purchase, with this number determined by the size of the system
26
SLIDE 27
Information Reporting Requirements
- Active and Idle State Efficiency Disclosure
Requirements
- Power and Performance Datasheet
(PPDS)
- Data Measurement and Output
Requirements
- Test Method
27
SLIDE 28
Active and Idle State Efficiency Disclosure Requirements
- EPA proposes to make data for all
required fields public for Version 1.0
28
SLIDE 29
Storage PPDS
- Power and Performance Datasheet
- For complex products, simple label won’t suffice
– Provide additional information about product – Energy performance, etc.
- EPA will develop an online Storage PPDS widget
– Used to directly compare qualified systems – Widget can be used on ENERGY STAR website or embedded in stakeholder websites
- PPDS information will be pulled from product
certification submissions
29
SLIDE 30
Performance Data Measurement and Output Requirements
- Power and temperature measurements can
be made via:
– Embedded measurement solutions – External solutions
- iPDUs
- Must meet accuracy reqts of embedded, make
available for purchase to customers
– Will pursue embedded solutions only in v2.0.
- Note: Temperature measurements optional
for v1.0
– Intend to pursue further in v2.0
30
SLIDE 31
Testing / Test Method
- Current test method references the SNIA
EmeraldTM Power Efficiency Measurement Specification V1.0
- But, some proposed deviations in Draft 3:
– Online 2 Storage products must include RAID controller – 24 hour Ready Idle Test – COMs must be disabled during active testing – Additional directions for testing NAS products w/ Block I/O
31
SLIDE 32
Remaining topics
- Power Modeling Presale Tool
- Development of updated SNIA tool
- Development of NAS file based energy
efficiency performance tool
