Multiple vCenter Clusters?

Hi All

I'd like to throw a quick question out there.

My company has 645 VMs spread over 13 ESXi 4.1 hosts (avg 49 VMs per host).

To improve performance they are suggesting I create 3 seperate Clusters and split the 13 ESXi Hosts among them. (i.e. 4 Hosts for Dev  / 4 hosts for Pre-Prod and 5 hosts for Production VMs). I don't think this is will have any performance benefit whatsoever, in fact as we dont have an equal number of dev, pre-prod and prod vms we could be in a situation of worse performance as more prod servers would be on fewer hosts than present.

All Hosts are IBM servers (64 Logical CPUs, 400GB RAM)

Personally I feel 1 Cluster is fine, and we simply need to add more Hosts to gain more CPU & RAM and have less VMs on Hosts -.i.e. less load.

What do you guys think? Is there any benefit to having multiple Clusters? Any personal experience would be good to know.

thanks
