What it isWhat it is NOT

Testing of outer bounds of what
Requirement to test outer bounds ofPartner intends to market as ENERGY all available configurations in a familySTAR qualified

amongst which qualified configurations

Waiver if verification of a “child”

configuration shows ENERGY STAR
requirements are not met. Partner is
responsible for ensuring thatintermediate configurations marketed
as ENERGY STAR meet all program
requirements and criteria.

Storageg proposal
p p• 3 test points:• To be defined:– Common product family attributes• key characteristics shared by all family members• e.g., drive type12

Scopep and inclusion of NAS• The Version 1.0 scope of the program is solidified tocover Online-2
Online-2, Online
Online-3-3, and Online-4
Online-4• Further portions of the market
may be added to the program,but in future versions

13

NAS

• Network attached storage raised again bystakeholders as an area for ENERGYSTAR coverage• EPA understands from related discussions
that it will be challenging to develop andagree on an appropriate
i t test
t t method
th d14

NAS• EPA will proceed with develop
pment of Version 1.0
and will incorporate NAS if it can fit into a
reasonable specification development timeline.
– Spring 2012

• Options:– Follow developments and integrate with Version 1.0(if timing allows)– Encourage continued development with reference in“Considerations for Future Specification Revisions”
section. Inclusion in v2.0.
15

Other data center storageg typesyp• Blade storage– EPA has longer-termginterest in capturing
pg blade storage
g in theENERGY STAR program– Level of testing complexity, and limits of available data, suggests
evaluation in future versions of the program (similar to ENERGYSTAR Computer Servers)• Server-based storage– Computer server used in place of a controller– “Controller-server” requires high capacity to amortize server
overhead enough to compete with standard storage products– … but might produce a more efficient solution in cases where aserver andd storage
tproductd t wouldld b
be purchased
hd separatelyt l– EPA proposes to leave such server-based storage products
outside of the Version 1.0 scope, to be considered in futureversions of the program.
p g16

Next stepsp• Evaluate comments• Agree on a product family
structure for testing• Communicate refinements
to representative testingstructure• Set approach for NAS in
V1 0 – evaluate now orV1.0
establish intent for next
version

• Considerations: adds complexity
evaluating incentive structures• Modules– Evaluate different pieces of device separately, sum to thewhole28

Active State• Draft 2 requires active efficiency disclosure for Version 1.0– Allows program to build critical mass of data for future evaluation– Customers know to look for efficiency information as part of theirpurchase decision– Sets stage for requirements in future versions of the ENERGYSTAR program29

Considerations• Robust product family structure still critical– Disclosed information appropriately broad togive customers an idea of where theirconfiguration falls, while not requiringexcessive testingg and burden to manufacturer• Configuration details tied closely to results

equipment,
it often
ft built
b ilt bby thithird-parties,
dti
includedi l d d as partt off ththestorage product; examples include embedded notebook
computers, displays, and network switches.
– Power supply requirements• EPA may be open to targeted exemption for such power supplies fromthe efficiency and power factor requirements in this section, provided it
cannot be used to exclude power supplies servicing the primary
components of the Data Center Storage product (e.g., controller,ddrawers).
)• EPA welcomes proposals from stakeholders on language to this effect.

• ENERGY STAR– EPA is also considering a requirement that all equipment in astorage system that falls under the scope of another applicable
ENERGY STAR specification (e.g. computers, servers) also beENERGY STAR qualified.
