Storage device requirements

Understand the different storage capacity requirements that should be considered when planning internal mode deployments and upgrades.

The general recommendation is 12 devices or less per node. This recommendation ensures that nodes stay below cloud provider dynamic storage device attachment limits, and to limit the recovery time after node failures with local storage devices. Expanding the cluster in multiples of three, one node in each failure domain, is an easy way to satisfy pod placement rules.

Storage nodes should have at least two disks, one for the operating system and the remaining disks for Fusion Data Foundation components.

Note: You can expand the storage capacity only in the increment of the capacity that is selected at the time of installation.
