FACT…

The rapidly growing carbon footprint associated with information and communications technologies, including laptops and PCs, data centers and computing networks, mobile phones, and telecommunications networks, could make them among the biggest greenhouse gas emitters by 2020”…

Data Center Designs are Inefficient

Power consumed = heat which must be evacuated Hot/cold aisles are often not set up properlyAirflow redundancy is needed account for hot pockets and humidityHeat dissipation is more expensive than power

As a Capitalist...

Energy costs are skyrocketing and consuming budgets$4.5 billion in electricity costs in U.S. in 2006*Costs to build new data centers are “material”: $1,000 per sq ft.Carbon offsets: $300 per server

* EPA report to Congress on Data Center Energy Efficiency, July 2007

“Over the next 5 years, most enterprise data centers will spend as much on energy (power and cooling) as they do on hardware infrastructure.”

Source: Gartner, February 2007

As an Environmentalist…

Data Centers are huge CO2 factories

1 full rack of blade servers = 20-25 kW = peak demand of 30 homes

U.S. data centers = 45 billion kWh, 1.5% of total consumption*

This electricity use has more than doubled since 2000

Every server removed or powered down saves ~12.5 tons of CO2 emissions

Equivalent to taking ~1.5 cars off the road (12,000 miles @ 20 mpg) or planting 55 trees a year

* EPA report to Congress on Data Center Energy Efficiency, July 2007

As a Data Center Operator

No more power available…

Want to move your data center?

Limited floor space / capacity

No new services!

Growth is constrained

Heat = server failure = service interruption

Volume Servers are Driving Power Consumption

Volume Servers are Driving Power Consumption

All servers = 40% of total data center electricity use

Volume servers = 85% of all server electricity use

Up from 70% in 2000

Volume server consumption has grown 17% annually since 2000

Situation:Hard to source qualified IT Staff – as servers setup across two data centers in a town 500 kilometers from the nearest large city.IT to pace up with business growth of 15% yearly.““We determined that if a server became corrupted, we would need six

or seven hours to fully restore it, . . . ”- Vishvas Chitale, Director, Chitale Dairy

Results:Reduced server hardware acquisition costs by 50%Cut software acquisition costs by 75%Reduced server deployment times from three weeks to three hours and restore a corrupted server in 10 minutes rather than 6 to7 hoursEliminated second data center, with consequent 50% reduction in power, cooling and real estate, by consolidating from 10 physical servers to 3.Reduced storage costs by 25%

Conclusions – How Customers WinServer consolidation and increased utilization decrease power consumption: energy savings are natural by products

Virtualization has inherent benefits such as workload mobility that allow for superior power management

Virtualization lets customers reclaim expensive data center floor space and avoid costly data center expansion

Do more with less – virtualization offers improved service levels, responsiveness and availability with a smaller energy footprint

Virtualization is the best initiative to reduce energy

1-800 Radiator

Situation:Rapid growth: 3 new franchises opened per weekOut of power, A/C maxed out, racks full“Before we knew it our computer room was almost at maximum power capacity, our computer racks were full, our switches were all used, and our air conditioning was on continuously. Rather than spend thousands on new power systems, racks, and air conditioning, we chose to leverage VMware’s product line to allow our company to keep pace with our growth.”
