Can I ask at what scale you’re running into issues? We’ve got about 500 VM’s running now in a single cluster.

You can have different cluster policy’s at least, don’t know what other benefits there are however as I haven’t noticed any.

We’re running into some performance problems stemming from having too many Hosts/VMs/Disks running from the same Datacenter/Cluster.  Because of that I’m looking into splitting the DC into multiple separate ones with different Hosts/Storage.

But I’m a little confused what the benefit of separating hosts into clusters achieves.  Can someone please explain what the common use cases are?  Since all the clusters in a DC seem to need to see the same storage, I don’t think it would help my situation anyway.

 

Thanks,

Ryan
