Description Ganesh Radhakrishnan 2016-10-04 01:47:43 UTC
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.
