Green IT Energy & Cost Savings Calculator

Green IT Piggybank

A large component of Green IT is server virtualization. A virtualized server environment is one in which several virtual servers (workloads) run on each physical server and all storage is shared.

The Green IT Energy & Cost Savings Calculator estimates the number of servers you can potentially reduce, 3-year energy costs with your current number of servers and the 3-year savings you could realize by reducing the number of servers. This information is budgetary and provided as an estimate only.

Enter the number of servers in the red box below.

*Cost Factors PER server:
Electricity$2,102.40(For 2 cpu server: $.11 per kw/h x .7 = .08 per hour per server)
Cooling$693.79(Electicity formula x .33 k-factor for cooling)
Provision / Maint.$3,600.00(30 hours per server per year w\ labor cost = $40/hour)
