Fundamentals of Data Centre Server Rack Power Architecture


1-day course

CPD Credit: 7 hours, C1/C2

Learning Objectives

To understand:

  • How server power supplies and rack power components are specified
  • How rack power architecture affects the Cost of Ownership
  • How rack power architecture affects the availability (uptime) of the services it supports
  • How to analyse and measure trade - offs between different architectures.

Course Programme

The course is set out in 11 modules as follows:

  1. Brief overview of data centre power consumption trends
  2. Key IT Power Metrics - definitions and practicalities
  3. Data Centre IT Rack Overview
  4. Power Architectures of key load elements (Servers, Storage, Networking)
  5. Evolution of Rack Power Architecture (AC-DC, Distribution, UPS etc)
  6. 12 Volt versus 48 Volt systems
  7. Rack to Data Centre Interface (PDU, Rectifier Shelf, Power Stip)
  8. Data Centre Tier Levels (and what this means for Rack Power)
  9. Servicing, Telemetry, Control
  10. Analysing Trade - offs
  11. Future Technology Considerations

Who Should Attend?

Data Centre operators, service providers, equipment buyers, managers and service personnel.

Anyone seeking to better understand cloud hardware architecture and how the choice of different rack power architectures can significantly affect uptime and running costs.
