Prerequisites
Administrative permissions on each of the servers that will become cluster nodes.
Permissions to Create Computer Objects and Read All Properties in the container used for computer accounts in the Active Directory domain.
User-managed MongoDB: For instructions on setting up a user-managed MongoDB on Windows, refer to the How to Create a User Managed MongoDB Instance article.
A minimum of 3 (1 primary and 2 failover) servers (virtual or physical), to act as Alteryx Server Controllers.
It is recommended to have an odd number of systems to maintain Cluster Quorum. If you do not have an odd number of servers, to maintain a Quorum, you should use a disk, file share, or cloud witness.
For high-availability, it is recommended that the servers be geographically dispersed. The failover controllers should never reside on the same Virtual Host, or within the same Data Center.
At minimum, each node within the failover cluster requires an Alteryx Server for High Availability license (SKU: AX‐147956).
For additional information on Microsoft Failover Clustering, refer to the Failover Clustering in Windows Server and Azure Stack HCI article.
