No Harmony in Harmonics

Harmonic currents can cause distortion in your electrical system. This white paper examines common causes of problematic harmonics, along with implications and resolutions for data center operators. Read More

Phase Change Cooling for Service Providers

This white paper examines an approach to data center cooling known as “phase change” or “two-phase” low-pressure pumped refrigerant cooling. It details the advantages of this approach over traditional computer room air conditioning (CRAC) methods, and it identifies the specific benefits — from lower OPEX and reduced energy requirements to optimized utilization of data center space — that service providers can realize.

Will Utilities Help Fund Thermal Storage?

A California utility will buy thermal energy storage systems and distribute them to commercial customers, hoping the move will shift power usage to off-peak hours. The concept may hold promise for the data center industry, where thermal storage is lightly implemented but offers the potential for significant peak-shaving savings on power bills. Read More

Oracle and the Dawn of Containment

Oracle has been honored by ASHRAE for design innovations in its Austin data center, which pioneered approaches to hot air containment and variable speed airflow that are now common in major data centers. Read More
