Use the Storage tab of the VMware Cloud Console to add customer-managed storage to an SDDC cluster.

The Storage tab of the VMware Cloud Console gives you the tools you need to add, remove, and reconfigure mountable storage (filesystems) like NFS.
Note:

VMware Cloud on AWS supports external storage starting with SDDC version 1.20. For information about upgrading an SDDC, see Submit an Upgrade Schedule Request.

SIOC (storage I/O control) is not supported for use in VMware Cloud on AWS datastores and will be automatically disabled.

NFS Datastores

NFS datastore support within VMware Cloud on AWS provides independent customer-managed scaling of compute and storage within an SDDC. This data storage may store Virtual Machines, Virtual Disks, Content Libraries, ISO, and similar objects. You can attach Amazon FSx for NetApp ONTAP storage target from the VMware Cloud Console. NFS datastores are associated with and attached to vSphere clusters.

VPC Peering for External NFS Storage

Beginning with SDDC version 1.20, you can request a VPC peering connection to external NFS storage. The SDDC must be a Single-AZ SDDC. The VPC peered with the SDDC cannot have an IP address that overlaps with the SDDC CIDR and must be in the same AWS region as the SDDC.  SeeVPC Peering for External Storage Connections for more information.
