Can I ask at what scale you=E2=80=99re running into issues? =
We=E2=80=99ve got about 500 VM=E2=80=99s running now in a single =

We=E2=80=99re running into some performance problems stemming from =
having too many Hosts/VMs/Disks running from the same =
Datacenter/Cluster. Because of that I=E2=80=99m looking into splitting =
the DC into multiple separate ones with different Hosts/Storage.
But I=E2=80=99m 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=E2=80=99t think it would help my situation anyway.

Thanks,
