Green datacenters

Green Datacenters

The Modern Data Center TRADITIONAL COMPUTER DATA CENTERS are contained

facilities which house the many large computer systems and associated components in isolated, temperature controlled rooms. Typically, a data center houses:

• Telecommunications systems• Storage systems• HVAC (heating, ventilation, air-conditioning) systems• Security systems• Redundant and backup systems (i.e., redundant storage systems,

emergency backup power generation)

The Modern Data Center DESIGN CONSIDERATIONS :

• Site selection: proximity to available power grids, telecommunications infrastructure, networking services, transportation lines and other environmental factors to be taken into consideration for data center design.

• Electrical power: backup power consists of one or more uninterruptible power supplies, battery banks, and/or diesel generators.

• Modularity and Flexibility: essential in allowing for a data center to grow and change over time; how readily upgradeable or interchangeable a data center’s components are.

“Modular” Data Centers

Energy & Environmental Costs A KEY ISSUE for modern data centers is the

amount of power drawn to run these facilities.

•For higher power-density facilities, electricity costs account for over 10% of the total cost of ownership (TCO) of a data center. In addition, data centers use diesel generators for backup power and major energy sources that heavily rely on coal production to produce electricity, contributing to the environmental hazard of running large, power hungry facilities.

•Information and communications technologies contribute 2% of global carbon emissions, with data centers accounting for 14% of that footprint3.

•At this trend, Greenhouse Gas (GHG) emissions from data centers are projected to more than double from 2014 levels by 2020.

Developing Efficiency Standards

LEADERSHIP IN ENERGY AND ENVIRONMENTAL DESIGN (LEED) standard developed by the US Green Building Council consists of a suite of rating systems for the design, construction and operation of high performance green buildings. Categories considered include Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality. Levels of certifications rank from Certified, Silver, Gold, and Platinum.

POWER USAGE EFFECTIVENESS (PUE) is a measure, developed by The Green Grid, of how efficiently computer data center uses its power; specifically, how much of the power is actually used by the computing equipment (in contrast to cooling and other OVERHEAD). Average data centers have a PUE between 1.8 – 2.5.

The Key To Green Data Centers

GREEN DATA CENTERS address two issues which plague the average data center:

1.The power required to run the actual equipment (CPU’s, memory, hard drives, etc).

2.The power required to cool the equipment (HVAC).

REDUCING THE POWER required will effectively lessen not only the energy consumption but also the impact on environment. Green solutions include:• More efficient hardware components and software systems (e.g.,

systems virtualization)• Innovative cooling systems• Using natural ways to cool equipment (evaporation, natural

chillers)• Building near advantageous natural resources or environments

(rivers, cold climates).• Effective server and rack management for better air-flow

Why Green?

WHY build a Green Data Center?• ENERGY EFFICIENCY = LOWER ENERGY COSTS• GREATER RETURN ON INVESTMENT (ROI) = MORE

INVESTMENT CAPITAL• LESS USE OF RESOURCES = LOWER
