In the past, power usage has been applied to overhead as a necessary operating expense like the cost of the space itself. But continually rising power costs have brought this issue to the forefront, and with good reason: EPA reports attribute approximately 2% of U.S. electricity consumption to enterprise data centres. On-going concerns for data centre managers include power reliability, supply and capacity, as well as the effect the cooling system has on power efficiency. It is estimated that cooling accounts for up to 40 percent of a data centre's total energy consumption. A Power Usage Effectiveness (PUE) ratio is used by many organizations to assess data centre energy performance. PUE is calculated as the total power supplied to the data centre divided by the power consumed by the IT equipment. The target is to get this ratio to equal 1; typical data centres have a PUE of 2.5, best-in-class data centres have a PUE of 1.6. A key step toward lowering energy cost is the ability to understand how power is allocated. Monitoring of the power draw at the cabinet level using power distribution units (PDUs) with a remote monitoring feature allows real-time assessment and the opportunity to quickly correct undesirable environmental changes.
NRB Telecom's Solutions to Promote Power Efficiency NRB Telecom Adaptive Enclosure Heat Containment (AEHC) Airflow Management System
Provides up to a 50% reduction in electrical cooling costs.
Basic PDUs offer simple, but highly reliable power distribution for equipment racks and other data centre applications.
Metered PDUs distribute power and provide real-time assessment of the current flow via a local display; allowing for the identification of current fluctuations and quick troubleshooting.
Metered/Remote PDUs provide all the benefits of basic and metered PDU's, while also allowing remote monitoring of the current draw via an Ethernet IP connection. With these PDUs, alarms can be set to warn when conditions exceed predetermined thresholds and facilitate the monitoring of a data centre's power usage effectiveness (PUE).
