Datacenter Efficiency and PUE Measurement
Good monitoring of datacenter energy consumption helps to improve its efficiency. The standard measurement of datacenter efficiency is Power Usage Effectiveness (PUE) which was introduced by Green Grid in 2007.
It represents the ratio of total facility power divided by the IT equipment power. According to Green Grid, PUE provides a way to determine:
- Opportunities to improve a datacenter’s operational efficiency
- How a datacenter compares with similar datacenters
- If the datacenter operators are improving designs and processes over time
- Opportunities to repurpose energy for additional IT equipment
- A design target or goal for new datacenters

PUE is a valuable metric to evaluate and manage your datacenter power. To measure datacenter efficiency, it is critical for IT managers and datacenter operators to know the components in this measurement. The two categories of energy in a datacenter are IT equipment energy and total facility energy, which includes power, cooling and other miscellaneous component loads such as lighting and security. The total facility energy is where we can gain energy efficiency.
Industry benchmarking of your datacenter efficiency can be the first step to reducing energy consumption and energy cost. This gives you a comparison to evaluate your current datacenter design and come up with strategies to make improvements.
Delta InfraSuite offers high performance and high efficiency power and cooling solutions. Our UPSs support your datacenter operation with industry leading power performance and efficiency (P/F >0.9 and Efficiency up to 96%) and offer modular features for flexibility, greater space utilization and agility. Our Cooling Solutions also feature high efficiency design. You can adopt the InfraSuite Rowcool series, an in-row modular design, which supports the concept of “pay as you go” and segmented zones according to applications. Its fan speed adjusts to load changes for significant energy cost savings. Besides infrastructure solutions, Delta InfraSuite also offers DCIM (Data Center Infrastructure Management) called InfraSuite Manager that provides IT managers an integrated platform to monitor the environment, manage IT equipment and track the energy performance of the datacenter to serve as a reference for PUE improvement. Delta InfraSuite Datacenter Solutions can help save at least 25% in energy consumption making Gold Level Datacenter or above an achievable goal.
Before building or upgrading a datacenter, it is essential to fully discuss with professionals and set your target for datacenter efficiency. Select the appropriate power and cooling systems to reach a reliable, energy-saving, maintainable, and manageable datacenter for your business goal. Building an energy-saving environment may increase costs, but reducing future operating costs is a worthy investment that eventually optimizes the total cost of ownership (TCO).
