Hardware Requirements
---------------------

A minimum |product_name| installation recommended for production consists of three nodes for storage and compute services with enabled high availability for the management node. This is to ensure that the cluster can survive failure of one node without data loss. The following table lists the *minimal* hardware requirements for all the three nodes. The recommended configurations are provided in the "Hardware Requirements" section of the *Installation Guide*.
