Data Center Infrastructure Management Flashcards

Which DCIM capability allows administrators to model planned equipment changes before physically implementing them?

Answer: What-if analysis

What-if analysis lets administrators simulate moves, adds, and changes virtually to assess impact before touching live infrastructure.

In DCIM, a 'stranded capacity' report identifies which condition?

Answer: Available power or cooling that cannot be used due to mismatches

Stranded capacity refers to resources (power, cooling, space) that are technically available but inaccessible because of mismatches between power, cooling, or space constraints.

What is the primary function of a Building Management System (BMS) integration within DCIM?

Answer: Aggregating facility-level sensor data into a unified dashboard

BMS integration feeds facility-level data (HVAC, lighting, generators) into DCIM for holistic monitoring and management.

Which metric does DCIM use to measure the ratio of IT equipment energy to total facility energy?

Answer: DCIE (Data Center Infrastructure Efficiency)

DCIE is the inverse of PUE, expressed as a percentage, representing IT load divided by total facility power.

A DCIM system triggers an alert when a rack's power draw exceeds its breaker capacity. What type of monitoring is this?

Answer: Threshold-based alerting

Threshold-based alerting fires notifications when a measured value crosses a pre-configured limit, such as exceeding breaker capacity.

Which data source is most critical for accurate DCIM floor-plan visualization?

Answer: As-built drawings with precise rack coordinates

As-built drawings with accurate rack positions and room dimensions form the foundation of correct DCIM spatial models.

In DCIM change management workflow, what is the purpose of a 'work order'?

Answer: Authorizing and documenting a specific infrastructure change task

A work order formally authorizes a specific task, tracks its status, and creates an audit trail for infrastructure changes.
