Known limitations identify platforms, devices, or functions that are not supported by this release of the product, or that do not interoperate correctly with it. Review these limitations carefully.

A link is required to complete some operations like replication in the workload factory user interface.

Storage efficiency

Storage efficiency cannot be disabled or enabled after volume creation.

Throughput capacity region support

Scale-up deployments

The following regions support up to 4 GB/s maximum throughput capacity for scale-up deployments: US East (Ohio) Region, US East (N. Virginia) Region, US West (Oregon) Region, and Europe (Ireland).

Scale-out deployments

The following regions support up to 3 and 6 GB/s maximum throughput capacity for scale-out deployments: US East (N. Virginia), US East (Ohio), US West (Oregon), Europe (Ireland), and Asia Pacific (Sydney).

Capacity management

  • The volume autogrow feature isn't currently supported for the iSCSI protocol.

  • When the automatic capacity management feature is running, manual capacity increase isn't allowed.

  • Disabling the automatic capacity management feature is only possible with the same permissions used to enable it.

Storage VMs

The number of storage VMs is limited per SKU. Creating storage VMs beyond the limitation isn't supported in workload factory.1

Refer to Managing FSx for ONTAP storage virtual machines in AWS documentation for the maximum number of SVMs per file system.

  • Only replication between FSx for ONTAP file systems is supported.

  • When you replicate a file system, all volumes in the file system use the same replication policy.

  • Only the last snapshot is available for restore.

Storage savings calculator

The Storage savings calculator doesn't calculate cost savings for the following configurations:

  • FSx for Windows File Server: HDD storage type

  • Elastic Block Store (EBS): st1, sc1, and standard volume types

  • Elastic File System (EFS): Bursting throughput mode
