Jira Ticket : https://rackspace.atlassian.net/browse/OSPC-68 Description: What is our virtual server over-commit ratio. This branch include update to default cpu_allocation_ratio to 8 from 1 and we have tried to provide a guideline to calculate this value for your hardware configuration used for openstack deployment.

| # CPU allocation Guide | ||
|
|
||
| By default openstack helm provide cpu allocation of 3:1. For a production deployment, cpu allocation ratio need to be decided based on multiple factors like hardware configuration of compute node (number of CPU core available ), required performance of workload, goal of efficient usage of available resource etc. | ||
| We are using HPE DL380 Gen9 Servers with 2 CPU socket and 18 cores per CPU socket and 2 threads per core to get cpu allocation for our deployment. We are considering below two cases here |

Updated cpu allocation ratio to 8
Documented a formula to calculate cpu allocation ratio based on hardware configuration and workload specifications.
