ATP ATP Capacity Planning & Scalability 2

Question 1

What does a 'power density map' help a data center manager determine?

Accepted Answer

Which rack locations can safely support high-kW deployments

Answer

A power density map identifies which rack positions have sufficient power and cooling capacity to support high-density deployments without overloading local infrastructure.

Question 2

Which approach best describes a 'modular' data center design?

Accepted Answer

Pre-engineered units deployed in phases to match demand growth

Answer

Modular data center designs use pre-engineered, pre-integrated pods or containers that are added incrementally, reducing upfront capital expenditure and over-provisioning.

Question 3

What is the significance of 'design load' versus 'installed load' in capacity planning?

Accepted Answer

Design load is the infrastructure's maximum rated capacity; installed load is the actual IT load deployed

Answer

Design load is the maximum capacity the infrastructure was engineered to support, while installed load is the actual power being drawn by deployed IT equipment.

Question 4

In a phased data center expansion, what is the main financial advantage?

Accepted Answer

Deferring capital expenditure until capacity is actually needed

Answer

Phased expansion aligns capital investment with actual growth, avoiding large upfront costs for infrastructure that may not be used for years.

Question 5

Which factor most commonly causes unplanned capacity exhaustion in a data center?

Accepted Answer

Poor visibility into real-time power and space utilization

Answer

Without real-time visibility into power, cooling, and space utilization, organizations often discover capacity limits only when they are reached, causing unplanned outages or deployment delays.
