The Environmental Protection Agency's Energy Star Program seeks to encourage computer makers to produce systems that are at least 80% energy-efficient. Most computers currently in use in business enterprises meet this target, yet those same enterprises could realize greater benefit from the Energy Star Program by making sure that when systems are inactive, they reduce their consumption of electrical power. An effective way to do this is through a managed services model in which power settings used across the systems in an enterprise are managed at the network-level rather than being adjusted on an individual basis.
IT companies estimate that at least 100 million computers in the world are left on at night. In terms of electrical consumption, this costs individuals and businesses several billion dollars annually. Using a sleep mode would typically reduce this consumption for at least 12 hours out of every 24. Allowing systems to go into hibernation mode would cut power consumption to zero when systems are not in active use. Windows OS has long provided power management features that allow end-users to take advantage of both these modes, but until recently, network power management software shipped as a tool that had to be deployed individually on every workstation.
With managed services, however, power management programs can be integrated with controls that already function network-wide. Workstations can easily be managed as a group without the installation of additional software, as long as a managed service client has already been installed on each client computer. IT administrators can then remotely manage each system, performing tasks such as defragmentation of hard drives as well as overseeing power settings.
