Over the years we’ve published many informational videos related to airflow management, cooling optimization, and data center efficiency, just to name a few. Today we take a look back at the top videos we’ve posted on our YouTube channel of all time.

1. Carbon Neutral vs. Net Zero Carbon: What’s the Difference?

Although carbon neutral and net zero carbon are closely related to each other, and even sometimes used interchangeably, there are some key differences between the two that are important to be aware of. For example, and perhaps the most important distinction, is what they mean in terms of reducing greenhouse gas emissions.

2. The Science of Data Center Containment

Whether you’re implementing hot aisle or cold aisle containment, modular or legacy containment, or soft or hard containment, the overarching goal is to prevent the mixing of cold supply air with hot exhaust air. How effectively you do this does somewhat depend on the method that is used as well as what other airflow management initiatives are in place, however, when it comes to reaping the benefits in terms of cooling efficiency and cost savings, we first need to understand the underlying science.

3. 4 Commonly Referenced Data Center Standards You Should Know

Genuine standards are important as they give us both the ability to benchmark and reference in terms of improving our operations, as well as comparing and contrasting sites in different parts of the world. This is why it is so important that we have a ‘standards’ framework that is generally global. With that being said, here are four commonly referenced data center standards in our industry that everyone should be aware of.

4. PUE Levels of Measurement: What You Need to Know

The Power Usage Effectiveness (PUE) metric is the most popular method of calculating energy efficiency in the data center. Although hotly debated for its limitations, its use is still very prevalent throughout the industry. Developed by the Green Grid, PUE is simply defined as the ratio of total facilities energy to IT equipment energy. It provides us a baseline to which we can measure against, but most importantly, it points us in the direction of where we’re not using our power effectively.

5. Hot Aisle Containment vs. Cold Aisle Containment: Benefits and Challenges

Data center containment has gone mainstream over the past decade, which has led to widespread implementation and adoption by many sites. In fact, according to a recent survey by the Uptime Institute, 80% of sites have implemented either hot or cold aisle containment. While the survey represented mostly larger facilities, many medium and small facilities have either implemented or are considering some form of containment. This high rate of adoption has left a lot of people asking the same question: Is it better to contain the hot aisle or the cold aisle?
