I will list all of them and refer to vSphere 7.0 if there are already mentioned.
vSphere Lifecycle Manager (vLCM)
The new and shining armor will likely eventually replaced the vSphere Update Manager. This can update beyond just VMware software but include drivers and firmware of the Servers where vSAN sits on. At a start, the below servers are supported:
- Dell 14G servers
- Dell MX series
- HPE 10G servers
- HPE Synergy
Then main attraction here is the vLCM which will handle all the upgrade and drivers and firmware together where no HCI today with the support of multiple server vendors can achieved today.
Together with vCenter Update Planner, you will even have a seamless upgrade of VMware software solutions that you are using.
