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

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
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
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 EmeraldTM 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
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
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
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
Remaining topics
• Power Modeling Presale Tool
• Development of updated SNIA tool
• Development of NAS file based energy
efficiency performance tool
32
Remaining Version 1.0 Timeline
• Draft 4 release in August
• Final Draft in late September / early October
• Final spec in October/November
