Service levels are an attribute of a capacity pool. Service levels are defined and differentiated by the allowed maximum throughput for a volume in the capacity pool based on the quota that is assigned to the volume.
Azure NetApp Files supports three service levels: Ultra, Premium, and Standard.
-
The Ultra storage tier provides up to 128 MiB/s of throughput per 1 TiB of volume quota assigned.
-
The Premium storage tier provides up to 64 MiB/s of throughput per 1 TiB of volume quota assigned.
-
The Standard storage tier provides up to 16 MiB/s of throughput per 1 TiB of volume quota assigned.
The throughput limit for a volume is determined by the combination of the following factors:
- The service level of the capacity pool to which the volume belongs
- The quota assigned to the volume
This concept is illustrated in the diagram below:
In Example 1 above, a volume from a capacity pool with the Premium storage tier that is assigned 2 TiB of quota will be assigned a throughput limit of 128 MiB/s (2 TiB * 64 MiB/s). This scenario applies regardless of the capacity pool size or the actual volume consumption.
In Example 2 above, a volume from a capacity pool with the Premium storage tier that is assigned 100 GiB of quota will be assigned a throughput limit of 6.25 MiB/s (0.09765625 TiB * 64 MiB/s). This scenario applies regardless of the capacity pool size or the actual volume consumption.
