The Basics - Getting Started

Standard Installation of MongoDB Ops Manager

Highly Available Ops Manager Architecture

In this scenario, a highly available Ops Manager requires 8 physical servers, not including the HTTP load balancer.

Apart from the HTTP Services, the solution requires 3 MongoDB replica sets of 3 data nodes each;

One each for the Application Database, and the Backup Blockstore Databases #1 & #2.

ClusterControl uses a single MySQL / MariaDB database server, to which its core services connect to store and retrieve data.

Redundancy can be achieved through deploying a database snapshot on a second node, and installing the ClusterControl applications.

With a HTTP proxy in front, requests can be directed to the live node. ClusterControl services such as auto-recovery should be stopped on the second node to avoid complications.
