Going Beyond PUE for Data Center Efficiency

Data Center Knowledge (Nov 29 2011) Cloud Computing , Servers

1. Today, many organizations are looking for new ways of doing more with less, reducing IT budgets or curtailing the incidental costs associated with data center expansions. And data center managers need to focus on creating efficient operating environments to augment the life of existing data centers. Data center efficiencies can be attained through increasing compute densities, creating cold aisle containment systems or more effective use of outside air, but the key component over time is to have an easily understood metric to gauge data center efficiency, and how much improvement is taking place. Power Usage Effectiveness (PUE) is one of the basic and most effective metrics for measuring data center energy efficiency. It is calculated by taking the total power consumed by a data center facility and dividing it by the power consumed by the IT equipment. The resulting ratio provides the effective power overhead for a unit of IT ... (Read Full Article)
