Power Distribution Units
Today we veer (slightly) from our primary interest in interoperability standards to explore the moment in best practice discovery and promulgation in the hardware supporting the artificial intelligence zietgeist. Use the login credentials at the upper right of our home page.
Carnegie-Mellon: Planning & Design Considerations for Data Centers
University of Kansas Data Center and Server Room Standards
Power Distribution Units (PDUs) are critical in data centers, serving as the backbone for reliable power management. They distribute electricity from the main power source to servers, networking equipment, and other devices, ensuring consistent and stable power delivery.
PDUs offer features like load balancing, surge protection, and remote monitoring, which optimize energy efficiency and prevent outages. By providing multiple outlets and circuit protection, they safeguard expensive equipment from power fluctuations. Advanced PDUs enable real-time data tracking, aiding in capacity planning and fault detection.
Ultimately, PDUs ensure uptime, operational efficiency, and scalability in data centers. We track, and sometimes participate, in the standards setting for these organizations develop the key standards that govern PDU design, safety, efficiency, and interoperability, influencing global manufacturing compliance:
UL (Underwriters Laboratories): Establishes safety standards like UL 60950-1 for IT equipment, ensuring PDUs prevent hazards in high-density environments.
IEC (International Electrotechnical Commission): Develops core electrical standards such as IEC 60950-1 and IEC 62368-1 for low-voltage safety and audio/video/IT equipment, critical for PDU power handling.
ENERGY STAR (U.S. EPA): Sets efficiency benchmarks for PDUs, promoting low-loss designs to minimize data center energy waste (up to 12% savings).Related:

With thanks to Richard Robben, President of True North Facility Management, the pledges to fund the NFPA Fire Protection Foundation Project: Evaluation of Electrical Feeder and Branch Circuit Loading accumulated to the requisite $24,000 to begin Phase I of two phases of a project originally begun by the University of Michigan to bring the National Electrical Code (NFPA 70) in line with federal energy conservation regulations that incorporate by reference the International Energy Conservation Code.
NFPA 70 is one of the most widely used standards for electrotechnology in the world. The University of Michigan began assertive advocacy on behalf of the US education industry in the NFPA suite in 1996 and that advocacy has expanded globally under two different private organizations: See About
Phase I is now completed. The Phase I Final Report (with public comments) is available in the links below:
REPORT – Branch Circuit Loading Phase1 FINAL
SUMM – Panel Comments – Branch Circuit Loading FINAL2
In October, the project Principal Researcher, Tammy Gammon, provided an update to the NFPA Research Foundation. Her slides are available in the link below:

Evensong “Sleep”
Composed in 2000 Eric Whitacre’s “Sleep” sets the poetry of Robert Frost to music. Widely acclaimed for its subtlety in dissonance and consonance. A classic in the contemporary choral repertoire.
“Grief” | Anna Ancher, Danish (1859 – 1935)
