Hello everyone, I have a question about vsan. We create a new environment for View, ultimately 1000 vdi - based on Vsan technology consisting of 8 hosts - DELL R740XD vSAN Ready Node located in 2 server rooms in 2 locations, 4 hosts per page. The distance between the server rooms is not great - about 400 meters of connected cisco nexus 9000 - 40 GB, and the hosts themselves are plugged in 25 GB when it comes to vSan connections. We have a vSAN Advanced for Desktop license. I know that the best solution would be a strechcluster, but the license does not allow it. At the moment we have one vSAN cluster configured with 8 hosts. I wanted to ask what error domain should be used to make it resistant to failure of one page - assuming, for example, no power in one of the server rooms. E.g: 1.2 domains with 2 hosts and 4 hosts as Standalone Hosts - with this configuration we have FTT at level 2. 2.4 domains with 2 hosts each - with this configuration we have FTT at level 1. 3.2 domains with 4 hosts each - with this configuration we have FTT at 0 level. How does such a configuration translate into the load on the environment - i.e. when we have options, e.g. options 1 - servers from domains 1 and 2 are working productively, and the rest are waiting for failure? Moreover, I wanted to ask what the best disk policy would be in our case. I assume that for connection servers, e.g. 1 failure - RAID-5 (Erasure Coding), and for vdi 1 failure - RAID-1 (Mirroring). I am asking for suggestions or possibly proposing an appropriate solution for our environment. Have a nice day.
