Hello EveyOne,

I am running vSphere 7 in my test environment and I am working with 3 host (new to the environment). I am looking towards deploying vSAN in my enviromnment where two host have local storage of 21 TB each but the third host doesn't have local storage except running esxi disk. I will be very grateful if anyone can guide me to which cluster method shall I proceed to. 2 node cluster or 3 node cluster? Does the disk requirement on all the hosts needs to be same. 

I will be very grateful for any suggestion.

Thank You
