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.

Adding HA pairs limitations

  • This operation might take approximately 30 minutes to complete.

  • Adding HA pairs limits the following operations: adding more HA pairs, provisioning IOPS, increasing SSD capacity, and updating throughput capacity.

Throughput capacity region support

Scale-up deployments

Scale-up configurations are supported up to 2 GB/s in all regions. 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 6 GB/s maximum throughput capacity for scale-out deployments: US East (N. Virginia and Ohio), US West (N. California and Oregon), Europe (Frankfurt, Ireland, and Stockholm), and Asia Pacific (Singapore and 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.

  • When automatic capacity management is enabled, a link is required to make sure volume inodes increase along with storage capacity.

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.

iSCSI protocol support

  • The iSCSI protocol is only available for FlexVol volumes. 1

  • Only a single LUN can be configured per volume.

Data protection

  • Snapshots cannot be deleted.

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

  • For long-term retention replication relationships, only the last snapshot is available for restore.

  • The following features aren't supported with immutable snapshots:

    • Consistency groups

    • FabricPool

    • FlexCache volumes

    • SMtape

    • SnapMirror active sync

    • SnapMirror policy rules using the -schedule parameter

    • SnapMirror synchronous

    • SVM data mobility (used for migrating or relocating an SVM from a source cluster to a destination cluster)

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

System Manager

System Manager doesn't support links for FSx for ONTAP connectivity.

AWS Secrets Manager support

AWS Secrets Manager isn't supported when using a Connector.
