Previously, we used VSC for two reasons - backing up datastores and setting recommended settings in the VMware environment. Now we have migrated from VSC to SnapCenter for backups, and we've discovered that if we hit "apply recommended settings", it does not "recognize" that our main cluster consists of four AFF systems. This matters, because the TR below recommends a different setting for AFF systems, but VSC applies the recommended setting for FAS systems. As a result, we had to manually correct that setting anyway, and VSC now reports that all of our systems "have issues" which is inaccurate.
Does anyone know if this situation is corrected in 7.2 or 7.2.1? I saw nothing in release notes about it. If it's not corrected, I'm thinking there's no value in keeping VSC at this point. Would love to hear anyone's thoughts!

I'm not exactly sure which setting you are referring to, but I'm guessing it's NFS.MaxQueueDepth. We still recommend changing it from the default in vSphere 6.5 which is 4294967295.
While TR-4597 and earlier releases recommended using 64 in general, and 128 for AFF, since then we have fully tested and recommend 128 for both FAS and AFF systems. This is the setting that 7.2 and 7.2.1 apply as well.
I am working with NetApp engineers to review and update these host settings as needed, so I welcome any other feedback on these.
Thank you Kari! Based on this information, I think I will go forward with the 7.2 upgrade and see if that corrects our issue. Hopefully it will update and show that we are "compliant" with the recommended standards again.
Upgrade is complete and indeed it appears to have worked, however the "About" button continues to show version 7.1P1 rather than 7.2 which we upgraded to. Do you know if this is a known bug? If needed I'll open a case. Just want to make sure the upgrade fully worked!
