 3. <a name="table-note-3"></a> RAM:
 
     - Redis uses a relatively large number of buffers, which enable replica communication, client communication, pub/sub commands, and more.  As a result, you should ensure that 30% of the RAM is available on each node at any given time.
 
     - If one or more cluster nodes utilizes more than 65% of the RAM, consider migrating resources to less active nodes.

Persistent storage is essential because Redis Enterprise also uses it to maintain the cluster and database health, configurations, recovery procedures, and more.
