Assigning disk ownership on AFF systems

Before using your All Flash FAS (AFF) system, you should assign disk ownership to maximize performance.

About this task

All Flash FAS systems use root-data partitioning to partition aggregates.

Twelve SSDs from each shelf are assigned to a node. One data aggregate is provisioned on each node.


  1. Assign disks in bays 0 through 11 to the first node in the HA pair.
  2. Assign disks in bays 12 through 23 to the second node in the HA pair.
  3. If required, repeat the procedure for additional disk shelves.
    You can partition up to 48 SSDs on an HA pair depending on your configuration.
