IT Technology Vendors

Between big tech giants

This collaboration should result in a better range of energy-efficientproducts (hardware and software)

are collaborating by discussing what works and what does not

Examples:

HP, IBM, and Sun are sitting at the same table to work out greenstandards with The Green Grid

Department of Energy (DOE) laboratories such as Lawrence Berkeley

National Labs and Pacific Northwest National Labs are cooperating in

development of research and best practices for green IT.

Government agencies like the Environmental Protection Agency (EPA)

are leading the effort to standardize metrics to measure energy

consumption

The Green Grid

founded in 2007

primary mission: to further data center energy-efficiency initiatives

Members:

IT equipment and component manufacturers

manufacturers of facility support equipment

data center operators and designers drive the development of

metrics that provide a meaningful measure of data center energy

utilization and performance,

standard protocols to facilitate collection, sharing, and reporting

of power and thermal data from IT and facilities equipment, and

design and operating strategies that promote optimal data center

energy use.

published a collection of white papers on data center metrics and

data management. .3 March 2014

ASHRAE

publishes a set of documents and manuals that provide

data centers with

cooling strategies that optimize cooling delivery,

data center temperature, and humidity profiles,

maximize the cooling delivered per unit of energy

applied

3 March 2014

The Uptime Institute

focuses on tools and strategies to maintain the

serviceability and reliability of data centers

sets various data center performance levels through the

tier system, which dictates equipment redundancy and

data center environment criteria to maintain a specified

level of system availability

Uptime has been adding energy optimization, as well as

other critical criteria for data center operation and

reliability, which needs to be factored in when

considering data center reliability and availability.

provides education and resources for data center

managers

It devotes a portion of its efforts to assisting data center

managers to identify energy-efficiency activities

3 March 2014

mission:

promotes energy efficiency worldwide to achieve a

healthier economy, a cleaner environment, andgreater energy security

Collaboration of Building Energy Management and ITEnergy Management:

Building automation systems (BAS) and Energy

management systems (EMS) IT departments operate in an environment

surrounded by sophisticated data acquisition,

analyses, and networking systems of which IT itself is

largely unaware

3 March 2014

A third of U.S. energy consumption comes fromcommercial buildings

Businesses are automating those buildings to reduce

costs and emissions

Will IT lead, or follow, the coming change? IT can have a green impact on a companys energy and

emissions:

start with the data center;

manage desktop energy use;

enable mobility

3 March 2014


14/26

Building automation systems

brains of commercial and industrial buildings that control

their own environments

mainly, lighting and temperature controls

Benefits: energy savings, improved occupant comfort, added

security and safety, and reduced maintenance costs

3 March 2014


15/26

Energy management systems

Central control of lighting, heating, ventilating, and air conditioningwith the goal of reducing the energy consumption

Almost every campus (corporate, medical, or academic) has an

EMS

Manufacturers have adopted automation for efficiency for industrial

systems Next:

how the EMS and IT worlds should converge?

The concepts center around removing the long-standing wall

between building networks and IT (tenant) networks

Other systems common in most buildings

For security, air quality, and life safety

Energy management systems

Information is the fourth utility after electricity, gas, and water

Cisco has proposed moving EMS to the IP network, not only for

efficiency, but also for the information synergies involved

Business information has a strategic and tactical value, and

information about the buildings performance is no different.

Protocols: Building systems operate on largely special-purpose open

systems (such as BACnet or LonWorks), and a few proprietary

systems remain popular.

both types of systems can talk to the IP network through

gateways Within the last few years, the building-control industry has

discovered XML. Middleware applications gather information and

normalize it for consumption by ERP, accounting, and other

enterprise applications.3 March 2014

Collaborating with Energy Utilities

Electric utilities provide incentives for their customers to move togreen IT

For example, the Pacific Gas and Electric Co. (PG&E) has

worked with several IT vendors to consolidate its servers, and

the company has developed new ways to measure and reduce

heat in data centers. They announced this initiative at a conference, where companies

such as American Power Conversion Corp. (APC), Eaton Corp.,

General Electric Consumer & Industrial, IBM, and others

gathered to discuss green computing and power-saving

initiatives. PG&E teamed with IBM Research to develop a tool to measure

the three-dimensional temperature distributions in its data

centers

EPA

US EPA ENERGY STAR data center rating system:

ENERGY STAR building program

data center rating system variation of the PUE (Power Usage Efficiency)

the rating system consider the percent of equipment

that utilizes virtualization technology and power

management and measuring technology began soliciting data centers to test the rating system.

Collaborating with Government Agencies

EU Code of Conduct for data centers: published in 2008

publication to help improve energy efficiency in data

centers

Other geographies: Australia is beginning to talk about

initiating a data center energy-efficiency effort and has

contacted IBM representatives about participating in

such a program.

Collaboration Within Your Own Company

The Uptime Institute recommended five issues for both short- andlong-term energy savings for data center:

Server consolidation, configuration, virtualisation

Enabling power-save features on servers

Turning off dead servers (no longer in use but running)

Pruning bloat ware (the application efficiency issue)

Improving the site infrastructure energy-efficiency ratio

By this, data centers can improve energy savings by 25 percent to 50

percent over a two-year period

3 March 2014


23/26

Collaboration Within Your Own Company

The Uptime Institute has developed a multifunctional teammethodology known as Integrated Critical Environment (ICE)

A tried-and-true method

send an e-mail to all users announcing server shutdown for

maintenance for a 24-hour period Active server users rebel instantly with reasons why their servers

cant be shut down

If no angry responses result, shut them off indefinitely and then

disconnect the servers

This frees up space, energy, and manpower

Collaboration and Carbon Trading

Governments usually have the role of regulating carbon emissionsthrough systems such as cap and trade.

In a cap and trade system:

the regulatory body sets a limit or cap on the amount of pollutant

a company can emit.

Companies are issued emission permits (the right to emit aspecific amount)

The total of allowances and credits cannot exceed the cap (the

total emissions).

Companies that need to increase emissions can buy credits from

companies that pollute less.

A purchase of credits is the trade

Summary and Conclusions

IT vendors have started to offer a significant set of integratedhardware, software, and services offerings to help customers

improve their energy-management initiatives.

Industry organizations are establishing efficiency metrics at the

server and data center level to integrate facilities and IT resources.

The EPA is establishing efficiency metrics at the server level as anextension to its ENERGY STAR workstation metrics.

Many IT companies are addressing the situation from end to end: at

the servers end through power management features, and at the

data centers end through integrated IT/facilities modular solutions.

The required collaboration for green IT is a part of the overall globalcollaboration required to solve the climate crisis
