Vendor impact assessment

Vendor risk class
medium
Procurement categories
infrastructure

Vendors supplying data center infrastructure, particularly liquid-cooling systems for high-performance computing and AI, will need to align their product offerings and services with the federal best-practice guidance once developed. This will likely impact design, efficiency, and integration requirements for government contracts.

Sample vendor questions

  1. Does your liquid-cooling technology meet or exceed anticipated federal best-practice guidelines for AI/HPC infrastructure?
  2. What are the energy efficiency and sustainability metrics of your proposed liquid-cooling solutions?
  3. How does your system integrate seamlessly with existing or planned high-performance computing and AI data center architectures?
  4. What support and maintenance services do you offer for the lifecycle of liquid-cooling systems deployed in federal environments?
