Considering Power Distribution Units (PDU) for your data center racks and IT equipment should require much more thought than simply selecting a ‘power-strip’ hardware configuration. If you care about Green energy initiatives and desire to save on electricity cost by making the most efficient use of the energy you use, make the move to intelligent rack PDUs if you haven’t already done so. This is particularly true for a new data center build and collocations. If you’re considering a collocation space, choosing the right PDU features will provide additional insight into your true energy use and a tool for capacity planning. We are now seeing large data center growth with collocation providers that charge clients based on actual energy consumed, kilowatt hour (kWh). A well thought out data center power distribution implementation will lead to reduced downtime, improved power monitoring management & control capabilities, and drive greater energy efficiency. The best suited Power Distribution solution requires considerable planning.
Not only for the environmental reasons that you may expect, but for the economic benefits seen by incorporating Green IT in the data centers. Going “green” means measuring, analyzing and controlling power usage to enable effective capacity planning along with aptitude to make change for decreased usage – all leading to improved efficiency and a controlled carbon footprint.
Yes, any Server Technology 3-phase Metered, or 3-Phase Intelligent (Smart, Switched, POPS) functional CDU products will provide Branch or Phase current displays for local hands-free viewing to immediately identify balanced loads. This information is also available remotely through any Intelligent CDU communications interface.

In most cases it is much more than ‘simply considering the power-strip hardware configuration’. How a Power distribution solution is implemented can lead to reduced downtime, improved power efficiencies, improved power monitoring, management and control. The best suited Power Distribution solution requires considerable planning. First, system solution level questions must be evaluated (1), key issues determined (2), and then the required CDU features can be realized (3).

The combined load of branches on a power strip may be capable of exceeding the upstream input protection. There is a fundamental misunderstanding of the purpose of the power strip internal fuse protection. The fuses are not there to keep the upstream breaker from tripping. Circuit protection within the power strip is there to protect the outlets and wiring to the outlets. Thus, a power strip may be protecting the branch outlets at 20A per NEC allowance while the upstream breaker is protecting the wiring and under-floor receptacle.
