 | Item | Description | Minimum requirements | Recommended |

-| Nodes<sup>*</sup> per cluster | At least three nodes are required to support a reliable, highly available deployment that handles process failure, node failure, and network split events in a consistent manner. | 3 nodes | >= 3 nodes (Must be an odd number of nodes) |
-| Cores<sup>*</sup> per node | Redis Enterprise Software is based on a multi-tenant architecture and can run multiple Redis processes (or shards) on the same core without significant performance degradation. | 4 cores | >=8 cores |
-| RAM<sup>*</sup> per node | Defining your RAM size must be part of the capacity planning for your Redis usage. | 15GB | >=30GB |

     - Clusters with more than 35 nodes are not supported. Please contact the Redis support team for assistance if your sizing calls for deploying a larger number of nodes.
 
     - Quorum nodes also must comply with the above minimal hardware requirements.
 
     - To ensure synchronization and consistency, Active-Active deployments with three-node clusters should not use quorum nodes. Because quorum nodes do not store data shards, they cannot support replication. In case of a node failure, replica shards aren't available for Active-Active synchronization.
