Amazon S3

Specifies that the data stored in the primary node is managed by Amazon S3. If you are using multiple Amazon S3 servers, specify a configuration file. Only the name of the configuration file should be entered and not the relative or absolute path name. The maximum size of the configuration file name is 12. The name of the configuration file can be added to a new or existing storage node. It can also be removed or modified for existing storage nodes. The configuration file name is optional.

Amazon S3 objects are organized into buckets. The storage node name represents the name of the bucket. Even though the bucket name can be as long as 63 characters, it is limited to 60 characters to be consistent with other storage node names.
