Want to Support High-Density Applications? Try a Three Phase PDU.
by RJ Tee
Categories: How ToSometimes, the road less traveled proves to be the better route. That’s certainly proven to be the case with Server Technology’s series of 3 phase PDUs. Once it was a less common, new approach to power distribution in the data center, now three phase PDU(s) sales have spiked over the past three years. One of the early challenges of three phase power was load balancing. In the past, this meant carefully dividing power evenly across the three branches of the rack PDU so that you could draw roughly similar current on each branch. This only worked in a perfect world where the rack is filled with a single type of device.

All About the New 3-Phase Power Video
by Linda Kennedy
Categories: Power Distribution & MonitoringIn Server Technology’s new video, “Take a New Look at 3-Phase Power Distribution,” the newly organized Server Tech Theater tackles the subject of 3-phase PDU power distribution to the rack and, more specifically, where and when you should and should not reach for an alternating phase rack mount PDU.

Shedding Light on Three-Phase Power - Part 2
by RJ Tee
Categories: Power Distribution & Monitoringn our previous post on 3-phase 208 power, we set the stage by describing some of the differences between it and single-phase power, including the fact that 120 + 120 does not equal 240 in the three-phase world. One thing that most of us know is that the rules for calculating capacity are different between the two. In this blog we will discuss the reason behind the difference and help build the case for the importance of a metered three-phase power strip.

Shedding Light on Three Phase Power - Part 1
by RJ Tee
Categories: Power Distribution & Monitoringart of the issue is that it is counterintuitive, particularly if you fully understand and have spent most of your life surrounded by single phase power. That is the form of power that most of us know because it is the way power is distributed inside our homes, schools, and workplaces. It’s how we understand the world of electricity: you plug in an appliance, and it turns on and works. Plug in too many appliances into a single receptacle, and the circuit trips. Power within the data center follows the same basic principles, although there is a bit more at stake with the tripped circuit breaker. Plus, most of our homes do not have redundant sources of UPS power. But I digress. With single phase, what you see is what you get. Single phase wiring for your home has two hot wires and a neutral. One hot wire and a neutral provides 120V, and two hot wires and a neutral provide 240V for larger appliances such as the oven and air conditioner.

It’s Not Just a Phase
by RJ Tee
Categories: Power Distribution & MonitoringIn the data center, our customers are always going through them. Equipment comes in, rack counts go up, and loads increase. Electrically speaking, many of our client’s centers are in a state of flux. Server Technology manufactures a variety of PDU types for whatever phase of development your data center happens to be in.

The Advantages of an Uncluttered Rack, Part II
by RJ Tee
Categories: Industry Trends & SolutionsAs mentioned in our previous post on Alternating Phase rack PDUs, many of us at Server Technology (including myself) like to talk about the benefits of our approach to handling three-phase power distribution within the rack. While the subject of three phase is de rigueur in the fashionable world of high density, there is a lot to talk about above and beyond the distribution of large amounts of power in a very small footprint.

Server Technology and the Internet of Things: Power at the Edge
by RJ Tee
Categories: Industry Trends & SolutionsBy now, you are familiar with the Internet of Things, or IoT. In fact, according recent statistics, you’re also likely involved in a deployment that has brought some of the challenges associated with the bulk data collection and storage issues presented by this technology. You've probably run into three phase PDU requirements or the need for a network controlled power strip.

Single vs. Three Phase Power Distribution - Know the Difference
by RJ Tee
Categories:Electricity is the single most important resource in a data center, as it’s needed for powering every system — from the servers on the floor to the lights overhead. Often the differences between a single phase PDU and a three phase PDU are not as complicated as they may seem, and even more often a 3 phase PDU is the right fit. At the same time, electricity is incredibly expensive, dangerous and easy to mismanage — especially when considering the sheer volume of power that is typically used. Some facilities, after all, use enough electricity to power hundreds of thousands of homes. Even though energy efficiency is now top of mind for data center administrators, there’s no getting around the fact that data centers consume a great deal of power. As such, it’s vital to have the correct underlying power distribution system in place before moving in and setting up any equipment.

How to Calculate Three Phase Power in the Data Center (And Why it’s Important)
by RJ Tee
Categories:To illustrate the importance of calculating three phase power in the data center, let’s pretend you are going to cook a meal for a big group of people. As simple as it sounds, first you’ll need to figure out how many guests will be arriving so you don’t run out of food and wind up in a pinch. In the data center, this planning process is called capacity planning. Only in this case, instead of feeding food to people, you are feeding electricity to servers.

Want To Support High-Density Applications? Try a 3 Phase PDU
by Josh Schaap
Categories: Power Distribution & MonitoringSometimes, the road less traveled proves to be the better route. That’s certainly the case with a less common, new approach to PDU design that employs 3 phase power distribution. In the past, this has meant dividing power into several branches within the rack PDU, but this new approach from Server Technology makes use of alternating each phase on a per-receptacle basis instead of per branch. As you can imagine, demand for more power in the cabinet is behind the move towards a 3 phase PDU in many data centers. If the search for more power is on your mind, alternating phase PDUs might be the answer to your problems.
