There is quite a bit of information that we can see, so lets break down the individual items that are useful from an NVMe Tiering point of view and the specific vSphere APIs that can be used to retrieve this information.

In fact, during VMware Explore, I had a number of users share with me in person that they not only updated to vSphere 8.0 Update 3 after learning about the feature but they were extremely happy that they could have their hardware was even more capable with just a software upgrade and workloads varied from general infrastructure VMs to the full VMware Cloud Foundation (VCF) stack.

Right before VMware Explore, I did have a couple of users who reported that after successfully configuring NVMe Tiering and rebooting their ESXi host, they noticed the memory capacity did not change. After sharing the details along with vm-support bundles, Engineering has identified the root cause.
