Description of problem: The sizing table in Chapter 2 of the OpenShift installation and configuration guide seems to be in correct. https://access.redhat.com/documentation/en/openshift-container-platform/3.3/single/installation-and-configuration/#sizing Also, the example below the sizing table (section 2.1.3) seems to be in correct. Version-Release number of selected component (if applicable): OpenShift v3.3 How reproducible: Per the sizing table :- Max. nodes / cluster = 1000 Max. pods / cluster = 120000 Based on the above, the max pods / node should be ~ 120 (120000 / 1000), whereas the table states the max. pods / node is 250. Also, the example below the table states - If you require 2200 pods, you need at least 20 nodes in your environment. This again doesn't add up - 2200 / 250 ~ 8 nodes ?? Whereas 2200 / 120 ~ 18.33 Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
