Storage class reference

Storage class reference

The available storage classes correspond to the predefined File Storage for VPC profiles. For storage classes with defined IOPs, make sure the IOPs are sufficient for the file share size you want to provision. For more information about the profiles and IOPs tiers, see File Storage for VPC dp2 profiles.

  • All file shares are provisioned with zonal availability, except regional classes which have regional availability.
  • All classes are elastic network interface (ENI) enabled.
  • All classes support cross-zone mounting.

Second-generation regional file share (rfs) storage classes are available in Beta for allowlisted account only. For more information, see Regional file shares overview. Second-generation regional file shares offer more flexibility for specifying capacity and performance along with regional availability. Encryption in transit for regional file share is not supported by the VPC File CSI Driver add-on.

Regional file share classes can be a better choice for workloads that prioritize durability, availability, or symmetric access across zones over low latency.

  • Volume size can range between 1 GiB to 32,000 GiB.
  • Volume performance is fixed at 35,000 IOPS.
  • The tunable throughput range is 1-8192 Mbps.
