I’d like to share with you my knowledge about replicate on your vSAN environment.
I was interested on how vSAN replicate his objects. So, I decided to make a LAB with HOL by VMware. You can follow this link if you want to do this LAB. For information, I configured six ESXi hosts, so I could get up to 1 for rule FTT when I tested Stretched Cluster, not more.
The goal of my study was, where vSAN synchronise an object like a VMDK file in his cluster as well as how was behaviour when I changed the setting of the SPBM. I was interested about the differences options available in SPBM (Storage Policy Based Management).
All of the results are in the bottom of this post. I hope you can find any help with this one.
First, it’s the behaviour of vSAN without Stretched Cluster that you can look at on this screenshot.
Then, This is a screenshot with Stretched Cluster.
I needed at least than 4 ESXi host to meet the requirement of line in Red, so I couldn’t do this test.
Thanks for reading.
