Description of problem:

In our 2.7 Support matrix we document SNO as Supported as Hub
but we do not document it:

https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.7/html/install/installing#requiremen[…]mendations

Customer would like to know what is recommended sizing for the Hub and how many Managed-Clusters can be created

So the concrete expectation is:

Add a new chapter into:
https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.7/html/install/installing#requiremen[…]mendations

• Considerations when deploying ACM on a SNO-Cluster

• minimum requirements e.g. 64 GB
• limitations as Bradd has highlighted

this document fits already well:
https://github.com/stolostron/rhacm-docs/blob/836623674edba15feddec214422025413949a683/install/cluster_size.adoc

Version-Release number of selected component (if applicable):

We should change docs for ACM 2.7 and later

Actual results:

Expected results:

A Customer should learn when looking into the docu,

• can SNO be a HUB
• what Size does the SNO need to have
• what limitations does it have
