    What recomended minimal host for make an cluster and run the DRS? I heard many people say the min is 2, and some other say is 3. Anyone here know what pro and cons if use 2 or 43 host on the host and DRS?

    While technically the minimum is 2, VMware generally recommends having at least 3 hosts for optimal performance and redundancy.

    More hosts mean

    DRS has more options to optimize resource allocation and placement of VMs.

    If you have a small environment with minimal downtime risk and budget constraints, 2 hosts might be sufficient. But for most production environments, having 3 or more hosts is recommended to ensure better redundancy, flexibility, and performance with DRS.
