Your university department is participating in an all-campus “green” challenge to find ways to reduce energy usage and greenhouse gases. Your network includes 10 physical servers, two switches, two backup power supplies, and one router/firewall in the computer room. Additional power is required to cool the room. You have a hunch that cloud computing could result in significant power savings. Suppose each server, backup device, switch, and router draws an average of 250 watts and that cooling draws approximately 600 watts. For comparison, you research the power requirements of the minimum number of devices necessary for the private cloud infrastructure you drew in Case Project 10-1. Approximately how many watts does your new infrastructure draw? By what percentage could you reduce your department’s energy usage by switching to cloud computing?
