CDCS® - Certified Data Centre Specialist

CDCS® - Certified Data Centre Specialist


The primary audience for this course is an IT, facilities or data centre operations professional working in and around the data centre and having the responsibility to achieve and improve high-availability and manageability of the data centre.


Participants must hold a valid CDCP® - Certified Data Centre Professional certificate in order to be able to register for the CDCS® class.


3 days.

Course Objectives

The Certified Data Centre Specialist is a three-day course designed to bring participants to the level of a suitable sparring partner with suppliers. They will be able to verify offers provided by vendors for correctness, effectiveness and efficiency. CDCS® is a must-have certification for professional data centre managers and personnel. CDCS® is a pre-requisite for individuals wishing to achieve the elite CDCE® (Certified Data Centre Expert) status.

After completing this course delegates will be able to:

  • Understand the design life cycle of data centres and the stages involved

  • Validate design plans, quotes and offers proposed by vendors/contractors
  • 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
