Data center power management solutions helps data centers meets demands on equipment, performance and reliability. For more than 28 years, Server Technology (News - Alert) has provided the biggest companies in the world with power management solutions. It offers solutions that give IT and infrastructure professionals the control to make accurate capacity planning decisions, reduce risks and meet energy efficiency goals.
In a whitepaper, “Data Center Power: deciphering the differences between available energy, usable energy and stranded energy,” Server Technology explores common issues faced in the data center industry and offers some advice on how to do things differently to raise awareness of how the implementation, deployment and usage of power can be accomplished more efficiently with a direct correlation to savings on energy use.
One of the main issues faced in the data center industry is the under-utilization of circuits, its effect on load balancing and how it’s related to the inability to use all or more of the allotted power services. To fix issues, it is crucial to understand the actual consumption or usable power of an IT device. When looking at available power and usable power, data centers need to consider that the faceplate or name plate value of a power supply can be up to 125 percent of actual usage.
The provisioning of power to a circuit is one of these under-utilization issues. By dedicating a circuit or multiple circuits to a device that does not utilize all of the allotted circuits is a cause for stranded power, which is important to have for power ‘reserves’ for devices and can help prevent a possible over current issue. Stranded power is unused or unusable power confined by a circuit connected to a server that will not consume the total amount/capacity of the circuit.
To figure out how much available energy there is, a data center needs to perform a study on actual usage over time to figure out the actual power numbers. The study will find out what power is available and how it is routed throughout the infrastructure. With the results of those studies, centers will be able to better balance or rebalance the power infrastructure and better utilize the available energy.
These studies can be possible with the measurements from a CDU either at the outlet or input feed level, and can be shared with a local monitoring system, such as Sentry Power Manager (SPM), a SNMP monitoring system for Power Distribution Units to poll, report and trend power, temperature and humidity readings from within the Server Cabinet, or with a DCIM, NMS or BMS.
