The only issue I encountered during deployment was with the hardware and not with vSAN itself. The disks in the new servers were installed at the factory as RAID disks. I had to mark them as non-RAID disks, so that vSAN would be able to see them correctly for addition to disk groups.

Prior to deployment, make sure you check your hardware compatibility prior, along with the drivers and firmware, because any one of those three things can cause an outage.

We had one issue with deployment, which was related to using the legacy vsphere client to place the hosts into maintenance mode. Which is easily resolved by using the web client for maintenance.

N/A

Yes. MTU settings will be vary depending upon network switch.

I tried to install it on one cluster and the host got stuck.

N/A

No issues encountered.
