Analysis and optimization of energy consumption of IT infrastructure*
Description: This is an accordance with Macedonian and regional energy research priorities basis of the countrys readiness and future potential, too. This project can help in development of policies , methods and knowledge needed for energy security, optimization and conservation in IT infrastructures. Proposed small R&D projects, will provide links between academia and industry. Small research project will contribute beside teaching and research activities the collaboration with industry sector. *This proposal was prepared in cooperation with Asseco SEE company (http://asseco.com/see/).

beginning Over the last 40 years, the data center has gone through a
tremendous evolution. ENIAC could be seen as the grandfather of the data centers we know today:
4
Prior to 1945-1955, the U.S. Army developed a machine called Eniac (Electronic Numerator, Integrator, Analyzer and Computer): weight 27mt, 160m2 of floor space, 150kW of power to deliver a compute performance of 0.05 MIPS and 6 full-time technicians to keep running.

past
During the 1960s, computers were large mainframes stored in rooms what we call a data center today. They were costly and businesses could rent out space on the mainframe to fulfill specific functions.
During the 1980s, the computer industry experienced the boom of the microcomputer era and computers were being widely used in the office.
When the dot-com bubble occurred in the 1990s, so did the boom of data centers. Businesses needed a quick way to establish presence on the Internet.
In 2006 a U.S. government study put total power usage of all servers in the U.S. at about 24 million MWh.
As of 2007, the average datacenter consumes as much energy as 25,000 homes.

present situation
I
Average of annual energy usage, a 400W server may use approximately 1,314 kWh a year (which is simply just powering it on) to about 2,600 kWh per year, energy costs are 800Euro to more about 1600Euro.

Effective approaches for optimization
The most effective approaches to infrastructure optimization include: Power management Monitoring and optimization DCIM - Data center infrastructure management High efficiency power supplies Low power processors Server virtualizations Cooling best practices Supplemental cooling
Virtualization has had the largest impact on the Data Centers physical infrastructure since the end of the Mainframe - Gartner 2013 Environmental Protection Agency concluded that best practices can reduce data center energy consumption by 50 percent by 2011.

Reliability average-downtime/year
While no down-time is ideal, the tier system allows for unavailability of services as listed below over a period of one year (525,600 minutes):
Tier 1 (99.671%) status would allow 1729.224 minutes or 28.8h Tier 2 (99.741%) status would allow 1361.304 minutes or 22h Tier 3 (99.982%) status would allow 94.608 minutes or 1.6h Tier 4 (99.995%) status would allow 26.28 minutes or 0.44h
99.999% Reliability average, 5.3 minutes Non-availability per year 99.9999%, 32 seconds 99.99999%+, 3.2 seconds

Power usage effectiveness (PUE)
15
The initial goal of PUE was to focus on reducing loss and increasing efficiency in the facility.
PUE= Total Facility Energy
IT Equipment Energy
PUE was developed by a consortium called The Green Grid.
Useful Computing
UPS - Uninterruptible power supply PDU - Power Distribution Systems
-
What is PUE
PUE (power usage effectiveness) is a metric used to determine the energy efficiency of a data center.
This is determined how much energy is used by the computing equipment in contrast to cooling and other facility overhead.
An ideal PUE is 1.0.
Anything that isnt considered a computing device in data center (cooling, lighting, ) falls into the category of facility energy consumption.

Real-world data center PUE
The average data center in the US has a PUE of 2.0 ("Report to Congress on Server and Data Center Energy Efficiency". U.S. Environmental Protection Agency ENERGY STAR Program)
State-of-the-art data center energy efficiency is estimated to be roughly 1.2.("Data Center Energy Forecast". Silicon Valley Leadership Group)
Google reported that the companys average PUE for 2011 was 1.14.
Microsoft PUE for newest data centers range from 1.13 to 1.2
eBay announced a new data center that has a PUE of 1.35
Yahoo has designs that can deliver a PUE of 1.08
