Disk Bursting
When to use this skill
- Spiky IO workloads
- Boot storms
Key concepts
- Credit-based — P30 and smaller; accumulate credits when below baseline, burst up to 3,500 IOPS / 170 MBps.
- On-demand — P30+ opt-in, pay-per-use bursting beyond provisioned tier.
- Burst telemetry visible in Azure Monitor disk metrics.
Common pitfalls
- Counting on credit burst for sustained load — credits exhaust in minutes.
