  • Understand redundancy levels for both the data centre design/setup and maintenance
  • Understand the various building considerations such as bullet proofing, mitigation of seismic activity, fire ratings and thermal stability
  • Understand how to install a raised floor that meets requirements, avoiding misalignment, level differences and leakage
  • Understand how to read a Single Line Electrical Diagram to identify and avoid the most common design issues
  • Choose the correct UPS and parallel configuration, learn and avoid classic parallel installation mistakes
  • Understand how to calculate battery banks, validate offered configurations to ensure they meet requirements
  • Understand what distance to keep to avoid EMF issues for human safety and equipment disturbances
  • Understand the fundamental cooling setup, CFM, Delta-T and other important factors
  • Understand contamination factors and limitations
  • Understand full details of fire suppression options, how to calculate gas content and verify installations
  • Understand how to measure data centre energy efficiency and how to improve it
