Data Center Energy Monitoring Made Easy

All data center lay a lot of stress on keep track of energy usage in the data centers. By monitoring the energy, it is easy to narrow down on the devices that will need replacement and the devices that have reached the end of their functioning life. With so much importance given to green practices and governments even giving incentives for green data center practices, data centers have set their own standard to live up to.

Power usage effectiveness (PUE) and data center efficiency (DCE) are two ways to assess the energy usage. PUE is defined as the ration of the power delivered to the data center to the power utilised by the IT equipments. DCE is the reciprocal of this ratio. The value of PUE should be as close to unity as possible.

Through this, we can locate the energy leak in the data center. The difference in the power delivered to the data center and the IT power consumption is due to the additional requirements in the data center such as lighting, cooling requirements, losses in the power distribution and protection units, UPS and battery maintenance etc.

Softwares are available to monitor the total input to the data center and the input available to IT infrastructure. They also record and store the readings over time and provide up-to-date and spot capture PUE values. With this, data centers can save substantial amounts on electricity bills. Also think of the free publicity you will get when you achieve the lowest PUE values. Remarkable, I know.

Data center efficiency, on the other hand, focuses on achieving the highest possible efficiency from all equipments. This is analogous to an over-demanding boss, if I may add. In softwares that calculate data center efficiency, PUE and DCE is recorded for a period of time and is compared with the industry standards to give you an insight on where exactly your data center stands when it comes to effective energy management. Some softwares even suggest ways to improve the efficiency. It is almost like having your own personal data center power management expert. You might want to look up PTS and 42U for more details if you are looking for power management tools.

Vantage data center reached 1.12 PUE in Santa Clara

Vantage Data Centers announced that it has managed to achieve an all time low PUE of 1.12 in its second data center in Santa Clara. This PUE value has managed to put Vantage data centers as one of the most energy efficient data centers in the world.

This data center was built from scratch in just eight months to meet a specific customer’s requirement. Inspite of the time constraint, the engineers have managed to build the data center with advanced and efficient electrical and mechanical designs that is capable of saving upto $72 million in power and cooling costs in its first ten years of operation itself.

This data center has been built according to the specifications of LEED Platinum Certification. It is the first fully vertically scalable data center. Capacity of the data center can be increased without compromising on the operation of the data center. It also uses free cooling mechanisms to cut down on energy costs and carbon footprint.

“V2 represents an entirely new data center vision, combining the option to lease space within a customized facility with the ability to grow within an existing building without disruption and with energy and operating expense savings on par with the world's most energy efficient data centers,” said Jim Trout, chief executive officer (CEO) of Vantage Data Centers. “V2 was built with unprecedented tenant collaboration, integrating decades of Vantage engineering and design expertise with tenant expertise and insight into critical requirements and opportunities for cost savings.”

“Vantage's collaborations with their customers are the closest thing I've seen to an integrated whole systems design process that involves two separate institutions, and that's not easy to do,” according to Jon Koomey, PhD, Consulting Professor of Civil and Environmental Engineering at Stanford University.”Typically such processes are found in product design inside companies like Apple, where the designers have complete control, but it's rare in the data center industry for separate companies to coordinate in this way in facility construction.”

Vantage has now begun construction of its proposed latest addition to the Santa Clara campus.

About Vantage Data Centers

Vantage Data Center primarily focuses on building efficient and easily scalable data centers which is customised according to the customer’s needs and requirements. It is headed by a team of experienced executives who constantly up the bar for data center excellence. For more information, please visit .

Intelligent Lighting Can Result in Reduced PUE

Redwood Systems’ recent installation got them a U.S Green Building Council LEED Gold certification in one of their data centers for their consistently low PUE rating. This was achieved due to an effort by Fenwick and West LLP, a firm specializing in life science and technology, to maximize energy savings. The firm decided to implement LED lighting in the data centers with centralised lighting control and a web- based access.

lightingThis improved the lighting quality tremendously and increased energy usage visibility. The lighting system was built around the data center’s energy sensitive mechanical systems. This system allows the data center to use lighting only when required and the brightness of the light can be adjusted too depending on the frequency of people motion in the room.

Redwood’s platform was installed on a separate track to the HVAC system. This system monitors the movements with such effectiveness that it not only enhances aisle configuration but also tightens security.

Since installing the system, the data center has been able to save upto 90% of the lighting expenses. LED does not significantly contribute to the data center heat thus reducing HVAC operations. The data center has been able to achieve an overall PUE of 1.18.

Other data centers should try and implement such lighting features to reduce energy consumption and increase data center efficiency.
