Question 1

What is the primary goal of data center capacity planning?

Accepted Answer

Ensuring resources meet current and future demand without over-provisioning

Answer

Capacity planning ensures that compute, power, cooling, and space resources align with current and projected workload demands without wasteful over-provisioning.

Question 2

Which metric is most commonly used to measure available white space capacity in a data center?

Accepted Answer

Square footage of raised floor

Answer

White space refers to the raised floor or usable floor area available for IT equipment, typically measured in square footage.

Question 3

In capacity planning, what does 'stranded capacity' refer to?

Accepted Answer

Usable capacity that cannot be utilized due to a constraint in another resource

Answer

Stranded capacity occurs when one resource (e.g., power) is fully utilized, preventing the use of available capacity in another resource (e.g., cooling or space).

Question 4

What planning horizon is typically recommended for a Tier III or Tier IV data center capacity roadmap?

Accepted Answer

3–5 years

Answer

A 3–5 year capacity roadmap allows organizations to plan capital expenditures, infrastructure upgrades, and phased expansions in alignment with business growth.

Question 5

Which tool is most effective for real-time capacity tracking across power, cooling, and space in a data center?

Accepted Answer

DCIM (Data Center Infrastructure Management) software

Answer

DCIM software integrates power, cooling, and space data into a unified real-time dashboard, enabling accurate capacity tracking and forecasting.
