iSCSI is SCSI over IP - you don't actually have "one". That's like saying "FICON, we actually have one!' > > > I have used VMWare and it performance leads a lot to be desired.

Of course, just like with a SAN, when connectivity is required over throughput you would use a core edge design with significantly cheaper hubs or switches to concentrate those connections. > > > Our enviroment is not lights out.

The people costs out here in Asia mean that there are shops that use people rather than automation because people are cheaper. Your ratio seems right given that you are a very small server shop. As the number of servers grows there are many skills that do not have to be cloned and the people to server ratio drops.
