Hello,
This depends on your proxy server capabilities ( Hardware, connectivity 
etc) & your VM Guest sizes and your backup schedule, Once you start 
pegging your CPU & overhead on the proxy server is high,time to add 
another SN( VCB Proxy), just add one VMserver at a time and watch the 
utilization.
Other factors that may influence your proxy server configuration might be 
compression\dedupe of VM Guest data & your SAN capabilities.

I have a follow-up question. When I arrived at my office this morning, I 
was
greeted by another SA with another Vmware ESX server that has two VMs to
back up. My question is simple. Do we need one proxy server per Vmware ESX
server, or can we have one proxy server handle backups for multiple Vmware
servers?
