@colleen_fun_181665 At the technical level, it is possible to run multiple Docker instances on 1 physical host but we don't recommend it and is not a supported configuration because the DSE instances will be competing for the same physical resources. More importantly, it introduces a single point of failure. For example, if the host has a hardware failure, all the nodes running on that host will be affected.

We only support 1 Docker instance per physical server. Cheers!
