Data Center Power Connections Demand a New Approach
One thing is certain when it comes to green data center power: phase load balancing, power distribution and stranded power have much to do with each other. As data centers become bigger and more companies deploy data centers of their own, the old way of connecting to data center power is as antiquated as a rotary phone.
A recent Server Technology (News - Alert) whitepaper states that the way data center administrators consider their circuits has changed because many circuits are either being under-used or overused, which is causing some disruption in load-balancing.
Administrators are beginning to think harder about how much power the devices in their data centers use as power is often being “stranded” and could be better put to use elsewhere. If a device’s power usage is determined only during peak data center power use times, the numbers administrators use to determine how much data center power they need is likely inaccurate. The power use needs to measure often to get a better handle on how much power is being stranded and if loads are balanced correctly.
In terms of load balancing, it takes some finessing to bring it into proper proportions. Knowing how much data center power is used by any given device throughout the day is a tricky variable. Easier to see are low levels of consumption versus high levels of consumption between upstream and downstream devices. What is perhaps more important when considering load balancing is to look at what data center power is being drawn through each individual line and circuit.
Finding a way around stranding power is also an important part of provisioning data center power. When a device that administrators believe needs a large circuit doesn’t actually use the all the power that has been assigned to the circuit, power is being stranded. While it is important to have the power in reserve necessary for a device that will need it, even if it’s one a limited basis, it’s also important not to reserve too much power to the circuit.
Administrators shouldn’t have to guess how much data center power is being used on any given device. Proper monitoring and thorough billing reports as well as attention to usage trends should provide the evidence needed to stay on top of data center power issues and will prevent power from becoming stranded. Using power calculators, administrators can determine the amount of power every cabinet in the data center requires.
The accurate approach to data center power estimates not only ensures proper operation, it also helps to eliminate waste and maintain a healthy budget over the long-term.

As the need to balance current and future IT requirements against resource consumption becomes more urgent, the data center industry increasingly views capacity planning as a way of achieving a critical component to planning a new build or retrofit. Data center capacity planning can be a complex undertaking with far-reaching strategic and operational implications. DCD Intelligence has therefore compiled this White Paper in order to share some industry insights and lessons on the practical steps that are needed to develop a successful power and capacity planning strategy.[Read More]
Server Technology had the recent opportunity, along with other partner companies, to participate in discussions across the globe with data center IT and facility managers as part of a road show seminar: Data Center Energy and Operational Efficiency.[Read More]
The demand for more power in the computer cabinet has led many data centers to upgrade to three phase power distribution. Proper three phase power distribution has traditionally meant dividing up power up into multiple branches within the rack PDU (Power Distribution Unit). In this paper we will explore the advantages of a new, less common approach to PDU design by means of alternating each phase on a per-receptacle basis instead of a per branch basis.[Read More]
Increasing powering and cooling demands within the data center have been the topics of choice for Data Center (DC) and Facility Managers for several years now. Increased power demands are a result of the need for more compute power and higher density devices have resulted. These high density installations include stacks and stacks of servers and the trend of implementing blade servers within these server "farms." Cooling problems are a direct result of the increased power demands based on the simple fact that more power increases the demand for cooling.[Read More]
