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 OpenZFS volumes have the following restrictions, which do not apply to access points attached to S3 buckets:
S3 access points can only be attached to volumes that are hosted on high-availability (HA) Multi-AZ and Single-AZ FSx for OpenZFS file systems. For more information about the types of FSx for OpenZFS file systems, see Availability and durability for Amazon FSx for OpenZFS.
The maximum number of S3 access points that can be attached to an FSx for OpenZFS (HA) file system is dependent on the file system's throughput. For more information, see Resource quotas for each file system.
S3 access control lists (ACLs) are not supported.
The same Amazon Web Services account must own the FSx for OpenZFS file system and the S3 access point.
You can only create S3 access points that are attached to FSx for OpenZFS volumes that you own. You cannot create an S3 access point that is attached to a volume owned by another Amazon Web Services account.
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.
