failure rate

Estimate replacement demand over replenishment time, then size for shortage risk and failure correlation. Distinguish shelf parts from runnable spare nodes.

Confirm the event definition and exposure, compare cohort rates, then test whether the cause follows a module, location or optical path.

Balance checkpoint pauses against lost work using job-level interruption data, while accounting for asynchronous durability lag.

Use the Llama 3 interruption record without turning job interruptions into device lifetime, predictable failures or a universal spare percentage.

Determine what the replacement count measures, compare equivalent device exposure and investigate differences by cohort, location, age, software and policy. Job-interruption statistics cannot supply a hardware replacement baseline.
