Hypersockets is best communication between LPARs. For communications between virtual machines within the same z/VM LPAR, virtual machines connected to the same VSwitch can talk directly to each other (still no wires).

"Does that mean that potentially that 1 mainframe has the equivalent of at least 130 network cards? I can see how most of the hardware is virtualized, but the networking I don't quite see, yet. How does that part work?" --------------------------------------------------------------------- (1) If these 130 servers communicated with each other a lot, then there is great savings by virtualization on the mainframe. On the mainframe IBM would have the traffic go on their Hypersockets, which basically passes it through memory. A good example of this is moving app servers and database servers on to the mainframe. Most of the traffic that they normally send is between each other. The same thing applies if they ftp data between themselves.
