Increasing Energy Efficiency with Virtualization
Energy consumption is a critical issue for IT organizations today, whether the goal is to reduce cost, save the environment or keep your datacenter running. In the United States alone, datacenters consumed $4.5 billion worth of electricity in 2006. Industry analyst Gartner1 estimates that over the next 5 years, most enterprise data centers will spend as much on energy (power and cooling) as they do on hardware infrastructure.
Save Energy by Eliminating Underutilization and Server Sprawl
VMware customers reduce their energy costs and consumption by 80% through virtualization. Most servers and desktops today are in use only 8-15% of the time they are powered on, yet most x86 hardware consumes 60-90% of the normal workload power even when idle. VMware virtualization has advanced resource and memory management features that enable consolidation ratios of 15:1 or more which increase hardware utilization to as much as 85%. With VMware virtualization customers can dramatically reduce energy consumption without sacrificing reliability or service levels.
Reduce the Environmental Impact of IT
Beside the company bottom line effect, virtualization is positively impacting the environment. Gartner2 estimates that 1.2 million workloads run in VMware virtual machines, which represents an aggregate power savings of about 8.5 billion kWh—more electricity than is consumed annually in all of New England for heating, ventilation and cooling.
At 4 tons of carbon dioxide (CO2) annually per server, these un-utilized servers produce a total of more than 80 million tons of CO2 per year. This is more than is emitted from the country of Thailand and more than half of ALL countries in South America.
