Bare Metal Requisites

  • CPU: The number of CPUs provided determines how many HostedClusters can run concurrently.
  • Recommended: 16 CPUs per Node for 3 nodes.

  • Minimal Dev: In a development environment, you may manage with 12 CPUs per Node for 3 nodes.

  • Memory: The amount of RAM impacts how many HostedClusters can be hosted.

  • Recommended: 48 GB of RAM per Node.

  • Minimal Dev: For minimal development, 18 GB of RAM per Node may suffice.

  • Storage: Using SSD storage for MCE is crucial.

  • Management Cluster: 250 GB.
  • Registry: Depends on the number of releases, operators, and images hosted. An acceptable number could be 500 GB, preferably separated from the disk where the HostedCluster is hosted.

  • Webserver: The required storage depends on the number of ISOs and images hosted. An acceptable number could be 500 GB.

  • Production: For a production environment, it's advisable to keep these three components separated on different disks. A recommended configuration for production is as follows:

  • Registry: 2 TB.
  • Management Cluster: 500 GB.
  • WebServer: 2 TB.
