Hello everyone, for project specifications we will have to use 3 servers to create a failover cluster for the management of a DHCP, these servers will have to be "independent", in the sense that they will not have the possibility to use external storage units and must, if not be a domain in its own right, be part of it. From here I get the problem that the disk to be used in the cluster will have to be a unit' terna to this group, and' a possible thing ? and if so, how?

    Hey,

    In case you need only DHCP failover you can configure it without a need in Failover Cluster. Might help:

    If you need Failover Cluster, you can configure it without a need in separate shared storage (SAN). You can use storage of your hosts with software-defined storage, which will create shared storage for Failover Cluster. You can use either StarWind VSAN or S2D.
