This article answers frequently asked questions (FAQs) about Azure NetApp Files Performance.

What should I do to optimize or tune Azure NetApp Files performance?

You can take the following actions per the performance requirements:

  • Ensure that the Virtual Machine is sized appropriately.
  • Enable Accelerated Networking for the VM.
  • Select the desired service level and size for the capacity pool.
  • Create a volume with the desired quota size for the capacity and performance.

There is no need to set accelerated networking for the NICs in the dedicated subnet of Azure NetApp Files. Accelerated networking is a capability that only applies to Azure virtual machines. Azure NetApp Files NICs are optimized by design.

How do I convert throughput-based service levels of Azure NetApp Files to IOPS?

You can convert MB/s to IOPS by using the following formula:

IOPS = (MBps Throughput / KB per IO) * 1024

How do I change the service level of a volume?

You can change the service level of an existing volume by moving the volume to another capacity pool that uses the service level you want for the volume. See Dynamically change the service level of a volume.

How do I monitor Azure NetApp Files performance?

Azure NetApp Files provides volume performance metrics. You can also use Azure Monitor for monitoring usage metrics for Azure NetApp Files. See Metrics for Azure NetApp Files for the list of performance metrics for Azure NetApp Files.

What’s the performance impact of Kerberos on NFSv4.1?

See Performance impact of Kerberos on NFSv4.1 volumes for information about security options for NFSv4.1, the performance vectors tested, and the expected performance impact.

Does Azure NetApp Files support SMB Direct?

No, Azure NetApp Files does not support SMB Direct.

Is NIC Teaming supported in Azure?

NIC Teaming is not supported in Azure. Although multiple network interfaces are supported on Azure virtual machines, they represent a logical rather than a physical construct. As such, they provide no fault tolerance. Also, the bandwidth available to an Azure virtual machine is calculated for the machine itself and not any individual network interface.

Are jumbo frames supported?
