Performance tiers for Azure Disk Storage are in limited preview
Published date: 21 July, 2020
Azure Disk Storage now enables you to set performance tiers (in limited preview) of your Premium SSD for a specific duration of time without increasing the capacity of the disk. Performance tiers provide the flexibility to achieve higher performance while controlling costs. This helps to sustain high-performance demands such as running a training environment during daytime, performance-testing or an event like Black Friday.
Your provisioned disk is first set to a baseline performance tier based on its size. At a time when your application has higher performance demands, choose a higher performance tier, then return your provisioned disk to the baseline performance tier once the high-demand period has come to an end.
For example, if you provision a P10 disk (128 GB), your baseline performance tier is set to P10 (500 IOPS and 100 MB/s). You can upgrade the tier to match the performance of P50 (7500 IOPS and 250 MB/s) and return to P10 when higher performance is no longer needed.
