Datacenter vs Cluster

We have all our Hyper-V servers globally managed by an SCVMM infrastructure. It manages all Windows host servers and their VMs. Some of those hosts are in load-balancing/fail-over configuration (what I would call "clusters"), others are simply standalone hosts. The Hyper-V connector gives the option to show the "DataCenter name" for the hosts. In the SIM, we chose to auto generate the datacenter names using the HostCluster (rather than the VMHostGroup).

I would expect that standalone servers are simply left without datacenter/cluster information (because they are not part of anything), but instead, Snow gathers all those standalone servers in a massive datacenter/cluster named after or SCVMM server. If I untick the "Put stand-alone servers into VMM Datacenter" setting in the Hyper-V connector, each standalone server goes into a datacenter/cluster named after the standalone server itself.

Is that the expected behaviour? Why are standalone servers showing any type of datacenter/cluster information?

How are you experts doing? What are your recommended settings?

(PS: I could not find a definition of "datacenter" or "cluster" as used by Snow.)


  • Hi Samuel. I am not using hyper-v, but vmware. So you know much more about this, but could you raise the minimum host to a higher number and then maybe not get a lot of small datacenter (when you untick) This is from SMACC, config, basic settings.
    • True, this would help but I also have some very small clusters ... I was looking for a more consistent solution.
