Just a heads-up to those who tend to install latest & greatest: the Element Plugin-in for vVCenter server which is commonly used by SolidFire and NetApp HCI customers, currently has its compatibility notes in Release Notes (v4.2.3).
Latest VCSA supported by this version:
VMware vSphere 6.7
◦ VMware vCenter Server 6.7 Update 1
Later this info will move to the NetApp IMT.
Newer versions may work, but also not. For example plugin v4.2.3 doesn't seem to work on the very latest VCSA (6.7.0.30000 Build number 13010631). It did work for me with two post-6.7U1 updates, but it doesn't work on this very latest one, so check this carefully before updating VCSA or the plugin...
