Description of problem:
lists limitations per domain for FC and iSCSI but no limitation for NFS.
Please state what we currently qualify and test in our documentation.
This bug has not been marked as blocker for oVirt 4.3.0.
Since we are releasing it tomorrow, January 29th, this bug has been re-targeted to 4.3.1.
Because RHV 4.1 is no longer supported, the chap-minimum_requirements_and_technical_limitations topic  is no longer available and was removed from the documentation for RHV versions 4.2 through 4.4.
It looks like the [Supported Limits for Red Hat Virtualization|https://access.redhat.com/articles/906543] topic answers these questions about maximums in the "RHV Manager Logical Entity Maximums" subsection, which states:
Maximum domains: 50 supported
Hosts per domain: No limit
Logical volumes per block domain (more): 1500
Maximum number of LUNs (more): 300
Maximum disk size: 500 TiB (limited to 8 TiB by default)
If that information does not answer the question or needs improvement, please explain how in a comment and reopen this BZ.
