I am new to vSan concept and practice.
I got a question on vSan concept:
Thanks!
(For reference, I attached two screenshots)
@CyberNils , Actually it is not mandatory for a vSAN node to have Disk-Groups - you can have compute-only nodes. If you meant you need minimum 1 Cache-tier device + Capacity-tier device per node to make a Disk-Group, that would be true.
Yes, you need at least one cache disk and one capacity disk per host.
@jerry5 Yes - Disk-Groups are comprised of 1 Cache-tier SSD/NVMe and 1-7 Capacity-tier HDD/SSD/NVMe on each node, these are local-only (e.g. physically in a single ESXi host).

Thank Nils, Bobkin: you guys save my time and energy!
I know, but it was pretty obvious that this guy was not trying to add a compute only node to an existing cluster... 🙂
