The Secret to Safe, Affordable Three Phase Power Distribution

Posted by Travis Irons on Aug 21, 2014 8:44:00 AM

Up until now, you were able to power your servers and applications using a 30A single phase, 208V power distribution unit (PDU) that contained two 20A circuit breakers. This power cord feeding this PDU contained two power wires and a ground wire. In order to properly distribute 30A of power without overloading any branch, you needed two 20A branches with an equal quantity of outlets per branch.

SPM Guides You Forward : Part Two - How much more can I grow?

Posted by Robert Faulkner on Apr 10, 2014 6:00:00 AM

This is the second in a series of blog posts providing tips and tricks for answering common data center questions with the use of SPM. Last month, I gave some guidance on answering, “How do I identify the best places to install new IT equipment?” Once you understand the ways SPM can help you with that question, the next question tends to naturally follow.

Server Technology Solution Partner Providers (Part 1 of at least 2 Parts)

I always find it interesting that the power chain is measured and monitored in multiple locations throughout most data centers but is often forgotten once the power enters the data center cabinet. Especially considering that roughly half of the power used (or more) can be traced directly to the cabinet (See Figure 1) and power is typically one of the greatest single costs associated with operating a data center. Often monitoring at the cabinet is the invisible line between the IT and Facilities groups. Even though monitoring at the in-feed of the Cabinet Power Distribution Unit (CDU) is really the same as monitoring at the Remote Power Panel (RPP) as the branch circuits coming out of the RRP are the in-feeds to the cabinet power distribution unit (CDU).

SPM Guides You Forward : Part One - Where do I put this?

Posted by Robert Faulkner on Mar 24, 2014 6:00:00 AM

Last month, I introduced a series of posts with the intent of outlining some tips and tricks, that I have shared with customers over the years, for using SPM in the data center and beyond. These posts are not intended to be a comprehensive instruction, but rather a starting point for discussion with one of our fine Sales Engineers or Technical Support staff.

A few words about replacing fuses and resetting circuit breakers

Posted by Bruce Auclair on Apr 8, 2013 1:59:00 PM

As a Systems Engineer who spends a fair amount of time responding to inquiries received through our Technical Support department I often hear "The PDU blew a fuse. I replaced it but it blew again. Something is wrong with the PDU. Please send me a new one."  Would that we could, but the PDU is doing what it should.  Following are some notes about why fuses blow and circuit breakers trip, and how to respond to re-energize the outlet branch safely and effectively.

What to consider when choosing a Power Distribution Unit

Posted by Bob Parente on Dec 20, 2012 1:13:00 PM

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.
