Overview

• History
• Background
• Data Center Overview
• Opportunity
• Recommendations
• Next Steps

3
History

• In January, the CEE Board authorized DC Server
  exploration findings to be reported in June
• In February, exploratory committee first convened
  
• Assessed the energy efficiency opportunities and
  potential CEE roles
• Recommending that the Board authorize an
  organizational committee to have an ongoing
  presence in this work area

4
Data Centers

• Are vital to the U.S. economy
• Require ever increasing amounts of energy to
  operate
• Can consume 25 to 50 times more electricity per
  sq. ft. than office space
• With electric cost per sq/ft 15-40 greater than
  office space

5
Data Center Definition

• A facility that contains concentrated equipment
  to perform one of more of the following
  functions
• Store
• Manage
• Process
• And exchange digital data and information
• LBNL Research Road Map

6
Characteristics of a Data Center

• House IT equipment such as
• Computers
• Servers (e.g. web, application and database)
• Mainframe computers
• Switches, routers, data storage devices, load
  balancers
• Wire cages or closets, vaults, racks
• Security and reliability
• Raised floors
• Specialized computer room AC systems
• Redundant and uninterruptible power supplies (UPS)

7
Space Type/Size
Who Owns Them?

• Server Closet
• Server Room
• Localized Data Center
• Mid-Tier Data Center
• Enterprise Data Center
• (Server Farms)

• Practically every mid-sized or larger company has
  some kind of data center
• Larger companies often have dozens of centers
• Most large cities have many data center buildings
• Cuts across virtually all markets

8
Enterprise Data Centers/Server Farms

• Google is building two computing centers, top and
  left, each the size of a football field, in
  Dalles, Ore.

• Data Center
• Energy Forecast

• Data Center
• Energy Use

• It is projected that DC server electricity use
  will more than double from 2006 to 2011
• From 59 billion kWh to 119 billion kWh (2.8 of
  electric use)
• If current trends continue could slow the rise to
  103 billion kWh

• In 2005 data centers used
• About 45 billion kWh roughly 1.2 of all U.S.
  electricity consumption (comparable to the amount
  used for color TVs)
• About 2.6 million kW (power demand)

10

• Server Energy
• Forecast

• Server
• Energy Use

• Electricity use of servers doubled from 2000-2005
• Aggregate growth rate of 14 in USA
• 2005 total usage is 23 billion kWh (0.6 of U.S.
  electricity consumption)

• Volume servers will grow more than 50 from 2005
  by 2010, while mid- and high-range servers will
  decline 20-30
• If power per server remains constantserver
  electricity use will increase by 40
• If power use per unit increasesserver
  electricity use will increase by 76

11
This Growth is Primarily Due to Increases in

• The number of data centers
• The server market that could double in 4 years
  (from 2.8 million units in 2005 to 4.9 million
  units in 2009)
• The energy intensity of equipment (more powerful
  equipment)
• The power density of racks and data centers (more
  equipment in smaller space)

12
Typical Data Center Energy End Use

• Server Processor 50
• Cooling Systems 35
• Other 13
• (power distribution
• about 11 of other)
• Lighting 2

Industry Market Characterization

• Data Centers are running out of space, cooling
  and power
• Cost of building a data center is significant
• Operations costs have significantly increased as
  of IT budget (power cooling)
• Difficulty achieving cooling needs
• Utilities cant always meet the energy demands

14
Industry Market Characterization

• Rapidly changing technology
• Operators are risk adverse
• Facility IT managers dont always communicate
• IT managers and equipment manufacturers are
  motivated to take action

There is a Buzz about this TopicIndustry has
Taken Notice
Hiding in Plain Sight, Google Seeks More Power
Tech firms get green by trimming big energy bills
Electricity-hungry equipment, combined with
rising energy prices, are devouring data center
budgets.
A new push for energy efficiency in the computer
Industry is sparking a bare-knuckles brawl, with
companies competing to add performance and save
power.

Data Centers Hog Energy and Are Paying Steeply
16
Data Center Efficiency Opportunities

• Improving the efficiency of the data center
  facility and systems
• Improving the efficiency of the IT equipment
• By improving the performance of the server,
  energy savings can be compounded by reducing
  energy losses and cooling loads

17
A Lot of Activity In this Area

• EPA (ENERGY STAR)
• DOE (Industrial Technologies Program- Save
  Energy Now)
• Industry Organizations taking action (Green Grid,
  and SPEC)
• LBNL
• ASHRAE
• Manufacturers
• Member Programs (PGE and Austin Energy)

18
Recommendations

• To establish
• An organizational committee
• A general work area framework
• To enable CEE members to
• Establish relevance in this fast-paced target
  market
• Fully leverage the numerous activities underway
• Identify and evaluate the many claims of EE or
  green DC

19
Recommendations

• Objectives
• Given newness of industry objectives include
• Building consistent consensus-based definitions,
  understanding of the industry, and knowledge of
  data center and server systems
• Identifying, clarifying and helping to validate
  energy efficiency opportunities
• Identifying recommended program strategies to
  help increase the energy efficiency of data
  centers and servers over and above that of the
  industry itself

20
Recommendations

• Work area scope
• Cover existing and new data centers
• Include the broad range of data center types and
  sizes
• Enterprise data centers
• Corporate data centers
• Server rooms
• Data closets
• Key related systems including
• Building infrastructure,
• Power supplies and HVAC

21
Next Steps

• CEE Board to vote on ongoing presence in work
  area
• If authorized, CEE will convene committee
• Develop work plan and plan activities
• Begin work
