A node fails burn-in twice and passes on the third attempt. Do you accept it?

Keep the full failure history and investigate what changed. One passing retry is evidence, but it is not a repair or an acceptance policy.

Foundational

🖧 Hardware & Cluster Build-Out

Burn-In and Acceptance TestingAcceptance testing checks that a new cluster meets agreed performance and reliability criteria. Sustained tests and comparisons between nodes help reveal defects before production.

🩺 Fleet Reliability & Observability🔒 Premium

Node Health Checks and Burn-InHealth checks look for faults before and during GPU workloads. Burn-in, pre-flight checks and continuous monitoring cover different conditions and need explicit acceptance criteria.

Foundational

🖧 Hardware & Cluster Build-Out

Colocation, Power Contracts and Site SelectionA suitable site must deliver the required rack power, cooling and service capacity. Contract terms and facility lead times shape both cost and deployment dates.
