Course Objectives

The ANSI/TIA-942 Standard specifies requirements and guidelines for the design and build of a data centre. It is intended for use by designers who need a comprehensive understanding of the data centre design. It encompasses Architecture, Mechanical, Electrical and Telecom requirements and guidelines, which are not always covered by other generic guidelines and so-called “standards”. Understanding the intent of the ANSI/TIA-942 Standard is of fundamental importance, not only for the successful implementation of the data centre, but also for its sustainable operations. In this three-day course, the participant will learn how to design an ANSI/TIA-942 compliant data centre. It will provide a clear understanding of the requirements of the ANSI/TIA-942 Standard and possible implementation variations. The course is well suited for all types of data centres, be it enterprise data centres or multi-tenant, third party data centres such as co-location, managed services and cloud service providers.

After completion of the course the participant will be able to:

  • Learn to properly comprehend and apply the ANSI/TIA-942 Standard requirements and guidelines
  • Understand the proper intent of the ANSI/TIA-942 Standard to avoid both over- and/or under-investment
  • Align the selection of redundancy levels and infrastructure investments to the business requirements
  • Understand the criteria and requirements for a high availability data centre design and how to effectively establish the data centre from the perspective of the ANSI/TIA-942 Standard
  • Understand how the ANSI/TIA-942 Standard relates to various worldwide standards
