QoS value limits

You can find information about the possible minimum and maximum values for Quality of Service (QoS).

  I/O size maximum value
Parameters Minimum value Default 4KB 8KB 16KB 262KB
Min IOPS 50 50 15,000 9,375* 5556* 385*
Max IOPS 100 15,000 200,000** 125,000 74,074 5128
Burst IOPS 100 15,000 200,000** 125,000 74,074 5128
*These estimations are approximate.

**Max IOPS and Burst IOPS can be set as high as 200,000; however, this setting is allowed only to effectively uncap the performance of a volume. Real-world maximum performance of a volume is limited by cluster usage and per-node performance.
