Number ofSockets-Blade/Multi-node: ≤ 4sockets per blade or node
Rack-mount orTower/Pedestal: ≤ 4sockets total

Blade/Multi-node: > 4sockets per blade ornodeRack-mount orTower/Pedestal: > 4sockets total8Additional Scope Evaluation• If Rack-mount or Tower/Pedestal,a) Managed– 1 or 2 Socketsb) Unmanagedc) Resilient– 3 or 4 Sockets

9Final Covered Product Types• All are AC power only
• Blade servers:– ≤ 4 socket per blade• Multi-node servers– ≤ 4 socket per node

• Rack-mount or Pedestal/Tower– 1 or 2 socket managed– 1 or 2 socket unmanaged– 1 or 2 socket resilient– 3 or 4 socket
10Final Covered Product Types• Note: All resilient servers are managed, but not
all managed servers are resilient. Resilientstatus takes precedence over managed status
for determining product type.

11

Criteria by product type
• All servers must meet:– Table 1: PSU efficiency– Table 2: PSU power factor– Section 3.3: Power management requirements– Section 3.5: Active state efficiency criteria

12Criteria by product type
• Rack/pedestal, 1 or 2 socket:– Section 3.6: Idle state efficiency criteria– Table 3: Minimum idle levels• Broken down by managed, unmanaged, resilient– Table 4: Adders• Apply as relevant given installed hardware• Buffered memory adders apply only to resilient servers– Section 6.1.2: Servers that cannot populate all sockets fortest must populate to max possible and meet idle power
requirements for full number of sockets.

• Rack/pedestal, 3 or 4 socket:– Section 3.7: Idle state efficiency criteria• Measure idle levels

13Criteria by product type
• Blade servers must meet:– Section 3.4: Thermal management and monitoring,shipping documentation– Section 3.8: Measure idle levels, per blade
consumption• Multi-node servers must meet:– Section 3.4: Thermal management and monitoring,shipping documentation– Section 3.9: Measure idle levels, per nodeconsumption

Single Configurations andProduct Families• For certification of a single configuration,
manufacturers shall test that configuration only.
• For certification of a product family
manufacturers shall select the configurations
described in the following slides:

Auxiliary Processing Accelerators(APAs)• Idle state power data with APAs removed shallbe used as PBASE for the purposes of qualifying
single configurations or product family test
points.
• To qualify systems to be sold with APAs:– Single Configuration: Idle state testing conducted andsubmitted both with and without APAs installed.
– Product Families: Idle state testing conducted andsubmitted both with and without APAs installed for thehigh performance, maximum power configuration.
21

Auxiliary Processing Accelerators(APAs)• Product family APA requirements must be met
fully for each APA that is intended to be soldwith the product family as ENERGY STAR.
• The measured idle power consumption of each
installed APA in a configuration shall not exceed
46 watts. This consumption shall be reported inthe QPX for each APA qualified with a Computer
Server.

22

Questions• The line is now open to receive any questions
related to evaluating Servers for certification, orfor questions about the Servers specification.

23

Reporting Requirements
A successful QPX test submission using the Computer Servers web
service will be required for a CB to maintain recognition.
CBs shall report the following data to EPA which includes both tested
and verified data and manufacturer provided information:
•••
•
•
•
•

General characteristics
Electrical characteristics
Active and idle power consumption and performance values for all tested
configurations
Available and enabled power savings features
Thermal characteristics and air inlet temperature measurements
List of qualified configurations, including SKUs or configuration IDsFor blades, a list of compatible blade chassis that meet qualification criteria

Fields are specified in the data reporting template (QPX). This template will be
released for CB and stakeholder review in the March timeframe prior to being
finalized.
24

Using the QPX• Single configurations shall have data from one
configuration provided in the QPX• For product families with multiple configurations,
all required testing configurations are reported inthe same data submission• Additional data may be required for APAs

• April:– First Version 2.0 products will appear on the ENERGYSTAR Qualified Product List

• August: Version 1.1 testing stops.
• September 2013: Off-season meeting• December 2013: Effective date.
28

Milestones: March• EPA:– Week of March 11th: Final Servers v2.0 published• QPX doc distributed for review– Mid-March to April: Review, processing of QPX,
administrative work

• Manufacturers/Partners:– Week of March 18th: May choose to begin testing tov2.0– March 29th: Submit feedback on EPA QPX• CBs:– March 29th: Submit feedback on EPA QPX
29

Milestones: April• EPA:– QPX review, processing complete– Begins accepting test result data from CBs– Products qualified to v2.0 begin showing up on ENERGYSTAR Qualified Product List

• Manufacturers:– May continue testing to v2.0 (no change)• CBs– Successfully test your XML system using the new Servers
v2.0 web service.
– CBs that do not successfully test the system will not
maintain their EPA recognition for the new spec.
30

Milestones: August• EPA:– August 30th: Stops accepting new productqualifications for Version 1.1.
– Existing products from Version 1.1 remain listed on
the Qualified Products List

• Manufacturers:– Must halt any v1.1 activities by August 30th

• CBs:– May not submit new data for v1.1 qualification starting
August 30th31

Milestones: September
EPA and stakeholders:• “Off season” meeting– SERT data review– SERT expansion possibilities, updates• DC power• New architectures• APAs– SERT test run time
– Testing and reporting of server thermal characteristics– Power management capabilities of computer servers– Auxiliary Processing Accelerators (APAs)– International Outreach• Open to additional suggestions for agenda
32Milestones: December
Effective date in mid-December• EPA:– Remove all Version 1.1 data from its Qualified
Product List
– Version 2.0 is now the only data listed online– “Unmask” anonymous SERT data

• Manufacturers– All products must be qualified to Version 2.0 to get
the ENERGY STAR label.
– Stop marketing products as ENERGY STAR thatwere ONLY qualified under Version 1.1.

ENERGY STAR Servers
International Scope•

EU:– New agreement for coordination of energy efficiency programs includes
servers– In force as of February 20th, 2013

•South Korea:– Plans to use SERT for national energy efficiency program•

China:– Evaluating SERT for use– US-China Clean Energy Framework•Japan:– Evaluating SERT for use•

Canada:– NRCan will use ENERGY STAR Servers Version 2.0, plus SERT•••European Free Trade AssociationAustralia
New Zealand36

ENERGY STAR Servers
International Scope• ENERGY STAR can actively promote ininternational community over the summer andfall.
– Workshop, calls, etc.
