Hello,
The opinions are wide ranging, however, if there is high IO ( Which it 
will be) requirement to backup VMIMAGES, VCB needs to be robust physical 
server, this server should ideally be Storage node for Networker  so that 
data flowing to the tapes from SN ( VCB Proxy  server) is lan free.
Among other justifications, consider, why you would use storage node vs 
going over lan for huge datastores, same is true for VMDK
 ( VMIMAGE) backups.
In my mind, vertulized server for VCB is  going in wrong direction.
HTH

VCB & Networker






VCB needs to be a physical server. I installed and configured on my 
networker server and now I'm having problems with my autochanger. Don't 
know if it's related but I'm having inventory problems and waiting for a 
writable tape error. 

My question is does the VCB proxy have to reside on the networker server 
or can it be any physical server?

apparently missed the 'NW server on same SAN' part.  At that point I'd be 
more inclined to make one of the various VMWare servers (perhaps the 
secondary VirtualCenter system) a storage node and use that to service VM 
backups.
