Number of SSDs required for AFA systems root partitioning

A certain minimum number of disks are required to use SSD partitioning on AFA systems.

• A minimum of 12 SSDs are required for root-data or root-data-data partitioning.

  This requirement assures that spare root partitions are provisioned.

• A maximum of 48 SSDs per HA pair (24 per node) are partitioned when root aggregates are provisioned.

The Disks and Aggregates Power Guide has more information about root-data partitioning.
