I finally found some anwsers here :
https://learn.microsoft.com/en-us/azure/openshift/openshift-faq#what-is-the-maximum-number-of-pods-in-an-azure-red-hat-openshift-cluster--what-is-the-maximum-number-of-pods-per-node-in-azure-red-hat-openshift
The actual number of supported pods depends on an application's memory, CPU, and storage requirements.
Azure Red Hat OpenShift 4.x has a 250 pod-per-node limit and a 250 compute node limit. These limits cap the maximum number of pods supported in a cluster to 250×250 = 62,500. These limits are the same for clusters created using User Defined Routing (UDR) and running version 4.11 or higher.
Could you please update in the ARM docs. accordingly ?
