Hi,
Recently I was involved in a vSAN Stretched Cluster 6.6 implementation. When I was checking failure scenarios with the customer a red light appears; What happens if two sites goes down? Can I power on virtual machines in the remaining site?
That was a great question! So I start searching official information about this and I found vSAN Stretched Cluster & 2 Node Guide. In this guide we can found a lot of information about vSAN Stretched Cluster deployment. In the page 133 I see this:
Because votes of components in 3 sites in vSAN Stretched Cluster, 2 failure sites results in a complete lost of services. All vmdk are inaccessible.
But I like testing things, so I test this scenario with a lot of configuration; PFTT=1, PFTT=1 and SFTT=1, Local Protection, etc and in each scenario after get down 1 of the production Sites and witness site (2 sites of 3) the result was the same, because de votes all vmdk were inaccessible and services of virtual machines goes down.
What do you think about this? I would like to hear your comments.
Best Regards!!
