on our LAB have one vsphere 6.0,
we have a old box running vSphere 5.5 and want to upgrade it to 6.0 and add it to the same vCenter with the first one.
the idea behind here is to create a VSAN with both ESXI 6.0
after the VSAN is created want to retired one of the ESXI and use just one ESXI with the VSAN.
is this even possible or risky ?
vSAN requires minimum 3 ESXi hosts.
Recommendation would be to go with 4 ESXi hosts if you want to tolerate 1 host|network|disk failure
and still meet the minimum 3 host criteria for newer VMs and VM In-compliance state
when you say just 1 ESXi host for VSAN. this is not currently supported nor will work...
Thank you for your answer.
so testing vsan is not a option anymore
You could always test it running it nested of course. William Lam has a whole bunch of articles on this topic:
