This section has confusing statement like:

> For non-cloud platforms, such as vSphere and bare metal installations, the only configurable technology is file storage.

This is not true in most cases and it depends on the storage solution in the user env.

https://docs.redhat.com/en/documentation/openshift_container_platform/4.20/html/scalability_and_performance/scalability-and-performance-optimization#specific-application-storage-recommendations

It looks like the current doc is way complex and we need to make it simpler.

What we usually recommend are:

1. Object Storage is best
2. RWX file storage if Object Storage is not available
3. RWO block storage if both of the above are not available, this is non-HA setup
