Architecture

In ONTAP, the underlying architecture for a bucket is a FlexGroup volume—​a single namespace that is made up of multiple constituent member volumes but is managed as a single volume.

FlexGroup volume represented as a group of FlexVol volumes called constituents

Buckets are only limited by the physical maximums of the underlying hardware, architectural maximums could be higher. Buckets can take advantage of FlexGroup elastic sizing to automatically grow a constituent of a FlexGroup volume if it is running out of space. There is a limit of 1000 buckets per FlexGroup volume, or 1/3 of the FlexGroup volume’s capacity (to account for data growth in buckets).

No NAS or SAN protocol access is permitted to the FlexGroup volume that contain S3 buckets.

Access to the bucket is provided through authorized users and client applications.
