Does this math need to be changed to 50*20 = 1000 being that the number changed from 250 -> 50?

@sakthi-vetrivel can you confirm the math that @troy0820 is mentioning? If correct can you please update. Once done I am good with the changes. |

This link doesn't exist anymore and linking to this documentation that once existed showed the limits of the OpenShift Container Platform and not Azure Red Hat OpenShift with having a limit of 250 pods per node. Rewording this to show that Azure Red Hat OpenShift only allows a capacity of 50 pods per node as a capacity and not link to the documentation will rectify the discrepancy. @sakthi-vetrivel

I went ahead and made the changes for the math and committed them to the repository. This PR can be closed. |

@troy0820 Thanks for doing that. #please-close |
