Optimize performance

This page describes how you can optimize Google Cloud NetApp Volumes performance by adjusting volume and client-side configurations. These adjustments enhance throughput, reduce latency, and improve overall data transfer efficiency for your applications.

Before you begin

Before you make changes to your volumes to optimize performance, review performance considerations .

Adjust volume settings

You can optimize performance by adjusting the following volume settings:

• Increase volume capacity: you can increase the capacity of your Premium, Extreme or Standard service level volume to improve maximum achievable volume throughput. For volumes of the Flex File service level, increase storage pool's capacity instead. For the Flex Unified or Flex File custom-performance, increase the storage pool's throughput and IOPS.

• Upgrade your service level: you can move a Premium service level volume to a storage pool with an Extreme service level to improve throughput.

• Use manual QoS pools to assign greater throughput: you can decrease the assigned throughput of larger volumes with low throughput requirements, and increase the throughput of smaller volumes that need higher performance up to the available pool throughput.

Increasing volume capacity and upgrading service levels are both non-disruptive to I/O workloads in process on the volume and don't affect access to the volume in any way.

Adjust the client

You can improve performance by adjusting the following settings on the client:

• Co-locate clients: latency results are directly impacted by the capabilities and location of the client. For best results, place the client in the same region as the volume or as close as possible. Test the zonal impact by testing latency from a client in each zone and use the zone with the lowest latency.

• Configure Compute Engine network bandwidth: the network capabilities of Compute Engine virtual machines depend on the instance type used. Typically, larger instances can drive more network throughput. We recommend that you select a client virtual machine with an appropriate network bandwidth capability, select the Google Virtual NIC (gVNIC) network interface and enable Tier_1 performance. For more information, see Compute Engine documentation on network bandwidth .

• Optimize your client settings: for Linux clients, see Optimize Linux NFS clients .

Manual QoS

Manual quality of service (QoS) in NetApp Volumes lets you adjust volume performance to meet workload requirements and control storage costs.

Manual QoS offers the following benefits:

• Cost optimization: scale volume performance within your storage pool capacity to optimize cloud costs.

• Instant throughput adjustment: adjust volume throughput without downtime.

• Disaster recovery cost reduction: lower QoS for replicated volumes to reduce disaster recovery costs for destination pools.

• Enhanced performance for clones or caches: increase performance for clone or cache volumes with small allocated sizes.

• Flexible workload management: use larger storage pools as containers for multiple workloads, adjusting each volume's throughput as needed.

Considerations

• You can manage manual QoS using the Google Cloud CLI, NetApp Volumes API, or Terraform. The Google Cloud console isn't supported.

• Manual QoS is supported for the Flex Unified, Standard, Premium, and Extreme service levels and isn't available for the Flex File service level.

Set up manual QoS limits

For volumes within a manual QoS storage pool, you can set throughput and capacity independently. The overall throughput of all volumes in a manual QoS pool is limited by the pool's total throughput. Pool throughput is determined by its allocated capacity and service level. For example, a 40 TiB Premium pool can achieve a maximum throughput of 2,560 MiBps at 64 MiBps per TiB, while a 200 TiB Extreme pool can support volumes with a combined throughput of 25,600 MiBps.

Once the manual QoS pool is set up, you can set the required throughput limit for each volume within it. The maximum throughput limit for a single volume is 4.5 GiBps, or 30 GiBps for large capacity volumes .

The pool and volume commands or APIs display available and assigned throughput values for the pool to help you manage the total throughput. To create a manual QoS pool and define volume throughput, see Create a storage pool and Create a volume .
