Power Consumption

Description

It is possible to reduce servers power consumption by selecting energy-efficient equipments that provides the same service.

Example

When purchasing servers, choose ones which power supplies meet the 80Plus eco-label (Platinum and Titanium levels). Also choose servers that are Energy Star labelled.

It is also possible to choose hardware architecture that suits the web application type. For example, physicalization is more suitable for a high-traffic website: using "n" very low-power CPUs instead of "n" virtual machines running on a physical server whose processor (Xeon, etc.) is often energy-intensive.

Validation rule

The number of ...	is equal to or less than
servers without an 80Plus Platinum or higher certified power supply OR not eco-labeled or labelled Energy Star for server.	0
