Different Types of Rack PDUs

Posted on September 10, 2019 by Jessica Ciesla

In layman's terms, a rack Power Distribution Unit (PDU) is a device that can be fitted with multiple outlets to effectively control and distribute electricity. The two main types of rack PDUs can be classified as either non-intelligent PDUs or intelligent PDUs. Creating the proper configuration for your data center will require you to first understand the key differences between these two types of rack PDUs.


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.
 


Virtual Power Button on the KX IV-101

Posted on August 27, 2019 by Jessica Ciesla

The Dominion KX IV-101 is the ideal solution for lab and IT managers looking to increase remote management and control capabilities, while simultaneously retaining flexibility, agility, and security best practices. It is the perfect solution for labs, control rooms and demanding broadcast applications. The single-port device now features a unique "Virtual Power Button" that can be used by authorized users to remotely power on / off computers without turning to a switched PDU.


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.
