Rack PDUs Outlet Density and Types

Posted on November 14, 2019 by Jessica Ciesla

As the need for power consumption per server has changed, so too have the outlet density and types of rack PDUs. In fact, in order to support the power-hungry IT equipment that seems to dominate data centers, rack PDUs have become increasingly more powerful. Today's data centers see densely packed racks, greater watts per square foot, and higher than every power consumption. Understanding rack PDUs outlet density and types is a vital to keeping data centers running properly, without overloading servers or creating costly outages.

What Is Environmental Monitoring?

Posted on September 18, 2019 by Jessica Ciesla

Data centers come in all shapes and sizes. They are built to securely store copious amounts of data. However, what many people don't know is that in order to hold all of the data, these centers must also consume a large amount of energy. In fact, some estimates show that data centers consume 1.8 percent of the total United States energy consumption every year. The large amount of energy that is consumed, as well as other factors, makes environmental monitoring a key component of data center management.

Power Monitoring And Metering

Posted on August 28, 2019 by Jessica Ciesla

In the current digital age, it is expected that data centers will continue to rise in both power consumption and complexity. In fact, it is predicted that the use of data will grow to exceed 160 zettabytes by 2025.  As the age of big data continues to grow, the challenge for data center operators will be to discover how they support additional data, remain energy efficient, and ultimately reduce costs. Power monitoring and metering are the two key components that will help data centers succeed over the next decade.
 

Common Electrical Terminology

Posted on August 20, 2019 by Jessica Ciesla

Data center managers are on a constant road of innovation. As they implement new solutions, and respond to increasing demands for power, they must consistently consider a wide range of electrical factors. Whether you are exploring the benefits of high-power rack PDUs with sensors, or just beginning to delve into best practice approaches to reduce the carbon footprint of data centers, the following electrical term definitions can help you to better understand the intricacies of rack PDUs. 

Comparing Annualized and Peak PUE

Posted on August 7, 2019 by Jessica Ciesla

The Green Grid introduced the Power Usage Effectiveness (PUE) metric in 2007, and it’s currently the de facto standard for measuring a data center’s efficiency. The traditional method of calculating a data center’s PUE is to collect the required data manually and add it to a worksheet at predetermined intervals, whereupon an application calculates the PUE. A more advanced method of obtaining the PUE is to use intelligent rack PDUs that take the measurements and transmit them to a DCIM power monitoring solution that automatically calculates the PUE. Many data center managers are still unclear on what PUE is, how it’s calculated and what it’s used for. Most managers understand that their PUE should be as close to 1 as possible, but they may not know why this measurement is desirable.
