Questions and Answers

What is the purpose of RLUs (Rack Location Units) in determining data center capacities?

  • To provide efficient use of rack resources (correct)
  • To determine the weight capacity of the building
  • To choose the location of the data center building
  • To design the structural layout of the data center

What is one of the limitations that may lead to a change in the project scope when designing for data center capacities?

  • District Budget (correct)
  • Building near a river
  • Rack Location Units
  • Structural Considerations

How does a raised floor in a data center contribute to flexibility in design and maintenance?

  • Reduces the weight on the structure
  • Enhances the cooling efficiency of the building
  • Increases the building height capacity
  • Provides flexibility in air conditioning, electricity, and network cabling (correct)
