Identify Facility Requirements – Worked Example

In the context of the NVIDIA-Certified Associate: AI Infrastructure and Operations exam, understanding how to identify facility requirements is critical for designing and deploying AI infrastructure effectively. This worked example walks through the step-by-step process of determining the facility requirements for an AI training cluster deployment.

Scenario

A company plans to deploy an on-premises AI training cluster consisting of 20 NVIDIA GPUs distributed across multiple servers. The facility must support the power, cooling, space, and networking needs of the infrastructure while ensuring operational reliability.

Step 1: Assess Power Requirements

Calculate total power consumption: Each GPU server consumes approximately 1.2 kW under full load. For 10 servers, total power = 10 × 1.2 kW = 12 kW.
Include overhead: Add 20% overhead for networking equipment, storage, and future expansion: 12 kW × 1.2 = 14.4 kW.
Verify facility power capacity: Confirm the data center can supply at least 15 kW to accommodate this load safely.

Step 2: Determine Cooling Requirements

Estimate heat output: Power consumption translates roughly to heat output; 14.4 kW power means approximately 14.4 kW heat dissipation.
Calculate cooling capacity: Convert kW to BTU/hr: 14.4 kW × 3412 = 49,132.8 BTU/hr.
Assess cooling infrastructure: Ensure the facility’s cooling system can handle at least 50,000 BTU/hr, including redundancy.

Step 3: Evaluate Space and Rack Requirements

Server size: Each server occupies 2U in a standard rack.
Rack capacity: A 42U rack can hold 21 servers; 10 servers require approximately half a rack.
Additional space: Allocate space for networking switches, power distribution units (PDUs), and cable management.

Step 4: Confirm Networking and Connectivity

Network ports: Each server requires at least 1x 10 GbE port for AI workload data transfer.
Switch capacity: Ensure the facility’s network switches support 10 GbE and have sufficient ports.
Redundancy: Plan for redundant network paths to maintain uptime.

Step 5: Verify Facility Infrastructure and Safety

Power redundancy: Check for uninterruptible power supplies (UPS) and backup generators.
Fire suppression: Confirm appropriate fire detection and suppression systems are in place.
Access control: Ensure physical security measures limit access to authorized personnel only.

Summary

By systematically calculating power and cooling needs, assessing space and networking requirements, and verifying facility infrastructure, the company ensures the AI training cluster can operate efficiently and reliably. This approach aligns with the knowledge required for the NVIDIA-Certified Associate: AI Infrastructure and Operations exam, specifically the 40% AI Infrastructure domain.
