Pricing

For detailed information about pricing for each service tier, see the Pricing page.

‡ Regional and zonal service tiers allow defining custom performance settings.

Basic HDD and basic SSD tiers

Basic-tier Filestore instances are suitable for file sharing, software development, and use with GKE workloads. You can choose either HDD or SSD for storing data, with SSD offering greater performance at a higher cost.

Basic HDD instances have a performance increase when the provisioned capacity exceeds 10 TiB. The performance of basic SSD instances is fixed regardless of the provisioned capacity.

While no practical limit exists across service tiers, instance performance may be delayed when supporting a large number of files.

† On GKE refers to basic HDD instances provisioned with the Filestore CSI driver.

Zonal

Filestore offers the zonal service tier (GA), providing the following benefits:

  • Instance capacity ranges from 1 TiB to 100 TiB
    • The zonal (1 TiB to 9.75 TiB) service tier with lower capacity range scales up or down in increments of 256 GiB (0.25 TiB)
    • The zonal (10 TiB to 100 TiB) service tier with higher capacity range scales up or down in increments of 2.5 TiB
      • This service tier and capacity range replaces the previously available high scale SSD, a legacy service tier
  • This service tier is suitable for high performance computing application requirements such as genome sequencing, and financial-services trading analysis.
  • Allows for non-disruptive upgrades (NDUs)
  • Supports custom performance that allows defining performance settings independently from capacity
  • The following quota parameters apply:
    • Zonal (1 TiB to 9.75 TiB) offers the same per project, per region, instance quota available in the regional and legacy enterprise service tier
    • Zonal (10 TiB to 100 TiB) offers the same per project, per region, instance quota available in the legacy high scale SSD service tier

When compared with basic SSD instances, zonal (1 TiB to 9.75 TiB) may provide a better option for users that require higher availability and lower capacity.

When compared with regional or enterprise instances, zonal (1 TiB to 9.75 TiB) may provide a more cost-effective option.

If not specified, the lower capacity range (1 TiB to 9.75 TiB) is the default setting at instance creation.

Zonal limitations

The following feature limits apply:

  • When pricing is implemented, applicable fees apply.

  • Capacity range selection is permanent. Once the outer limits of the instance capacity are met, the service tier does not scale up or down to a new capacity range. If greater or lower capacity is needed, you must create a new instance with the service tier and capacity range you want to use.

Regional

Filestore offers the regional service tier (GA), providing the following benefits:

  • Instance capacity ranges from 1 TiB to 100 TiB
    • The regional (1 TiB to 9.75 TiB) service tier with lower capacity range scales up or down in increments of 256 GiB (0.25 TiB)
      • This service tier and capacity range replaces the previously available enterprise, a legacy service tier
    • The regional (10 TiB to 100 TiB) service tier with higher capacity range scales up or down in increments of 2.5 TiB
  • Optimized for enterprise-grade network attached storage (NAS)
  • Provides regional storage resilient to zone outages which supports the following:
    • Data replication across multiple zones within a region
    • High availability for mission-critical, high performance computing workloads running within a large namespace
  • Allows for non-disruptive upgrades (NDUs)
  • Supports custom performance that allows defining performance settings independently from capacity
  • Supports linear performance that scales with capacity, within the parameters of the specified capacity range
  • The following quota parameters apply:
    • Regional (1 TiB to 9.75 TiB) offers the same per project, per region, instance quota available in the legacy enterprise service tier
    • Regional (10 TiB to 100 TiB) offers the same per project, per region, instance quota available in the legacy high scale SSD service tier
  • Offers pricing that matches the legacy enterprise service tier

If not specified, the lower capacity range (1 TiB to 9.75 TiB) is the default setting at instance creation.

Regional limitations

The following limitations apply:

  • The regional service tier can't be combined with the Filestore multishares feature.

  • The regional service tier can't be combined with the GKE Filestore CSI driver.

  • 10 TiB regional instances must be created with the higher capacity range specification (10 TiB to 100 TiB).

  • The same limitations that apply to enterprise backups also apply to regional backups.

    • Backup restore operations are only supported when restoring to a new instance. For these operations, the new instance must match the service tier and also accommodate instance capacity greater than or equal to the size of the backup.

    • For a detailed description of backup limitations, see Backups.

  • For a detailed list of limitations by service tier, see Quotas and Limits.

  • While performance scales linearly with capacity, note that a 10 TiB enterprise instance will have better performance than a 10 TiB regional instance.

  • Performance scales linearly with capacity within the parameters of the specified capacity range. Performance is not linear between the two regional capacity ranges. A regional instance with 9.75 TiB of capacity will have better performance, for example, with an upper limit of 117,000 Read IOPS, than a regional instance with 10 TiB of instance capacity, with an upper limit of 92,000 Read IOPS. For more information, see Performance.

  • Capacity range selection is permanent. Once the outer limits of the instance capacity are met, the service tier does not scale up or down to a new capacity range. If greater or lower capacity is needed, you must create a new instance with the service tier and capacity range you want to use.

Legacy service tiers

Filestore's legacy service tiers include the following:

  • Standard
  • Premium
  • High scale SSD
  • Enterprise

Should you use a legacy service tier?

  • Basic HDD replaces the standard service tier.
  • Basic SSD replaces the premium service tier.
  • Zonal (10 TiB to 100 TiB) replaces the high scale SSD service tier.
  • Regional (1 TiB to 9.75 TiB) replaces the enterprise service tier.

When creating new instances, users are strongly encouraged to use these replacements. Legacy service tiers will continue to be supported for specific customer use cases. For example, the legacy enterprise service tier is still available for users requiring Filestore multishares or users requiring backups for existing enterprise instances. For more information, see Regional limitations.

These create operations are not supported through the Google Cloud console and must be made directly through the Filestore API or by using gcloud.

Legacy enterprise service tier
