Your memory serves you well genixia, and while the company does have a nice bank balance my boss spends money as if it was his own.

These will be used in standard racks and only be connected to servers in that rack. At this time I am uncertain as to how many servers will be in each rack.
So the stackable & long distance options sound overkill.
The setup will primarly be used for ghosting and testing the servers, in case that makes a differance.

So far it seem like a std KVM switch would do the job though.
