Can Using VMware Save on Power and Cooling Costs?

If you work in a data center, you know that one of the biggest topics being discussed right now is the crazy amount of power and cooling that is being consumed in the data center.  Data center owners and operators, if they haven't already, will be taking a careful look at this situation and quite possibly will start raising rates to compensate themselves for this increase. 

This week on VMware's VMTN Blog Site - The Console - Bogomil Balkansky, director of product marketing for VMware, posted his thoughts about this very topic, and how he and others believe that VMware can help out.

He writes:

While a typical server 10 years ago consumed 100W of power, the average server today consumes four times as much. Servers would use about 30% of their peak electricity consumption while sitting idle, which is often more than 80% of the time. Imagine your SUV going through gallon after gallon of gas while sitting in the garage. And to make things even worse, the density of servers per square foot has doubled at the same time – from 7 servers per rack to 14 servers per rack. The overall power density of the datacenter is increasing by 15% per year. All the electricity consumed by servers is transformed into heat – so to prevent data centers from turning into hot houses, about 125% more electricity is consumed by the cooling equipment.

IDC calculates that the total power and cooling bill for servers in the US stands at a whopping $14 billion a year, and if the current trends persist, the bill is going to rise to $50 billion by the end of the decade. The growth of datacenter energy spending far outpaces the rate at which IT budgets grow, dangerously crowding out other vital IT initiatives and projects.


We estimate conservatively that for every workload moved from a physical to virtual environment, customers can save about $290 in electricity costs, and about $360 a year in cooling costs. The more important thing is that these savings accrue year after year.
