Access points naming rules, restrictions, and limitations
When creating an S3 access point you choose a name for it. The following topics provide information about S3 access point naming rules and restrictions and limitations.
Access points naming rules
When you create an S3 access point you choose its name. Access point names do not need to be unique across Amazon Web Services accounts or Amazon Web Services Regions. The same Amazon Web Services account may create access points with the same name in different Amazon Web Services Regions or two different Amazon Web Services accounts may use the same access point name. However, within a single Amazon Web Services Region an Amazon Web Services account may not have two identically named access points.
S3 access point names can't end with the suffix -ext-s3alias, which is reserved for
access point alias. For a complete list of access point naming rules, see
Naming rules for Amazon S3 access points
in the Amazon Simple Storage Service User Guide.
Access points restrictions and limitations
S3 access points attached to FSx for ONTAP volumes have the following restrictions, which do not apply to access points attached to S3 buckets:
You can only create an S3 access point in the same Amazon Web Services Region as the FSx for ONTAP volume that you are attaching it to.
The same Amazon Web Services account must own the FSx for ONTAP file system and the S3 access point. You can only create S3 access points that are attached to FSx for ONTAP volumes that you own. You cannot create an S3 access point that is attached to a volume owned by another Amazon Web Services account.
You can only create and attach S3 access points to FSx for ONTAP file systems running NetApp ONTAP version 9.17.1 and later.
For a complete list of all access point restrictions and limitations, see Restrictions and limitations for access points in the Amazon Simple Storage Service User Guide.
