In the ISP/ASP redbook, we were only partly joking when we suggested that you should draw network diagrams of your penguin colony without showing z/VM, for certain audiences. As Mark said earlier, replace the "z/VM TCP/IP" label with one that says "Router", and the "HiperSockets" label with one that says "Ethernet". It is not totally accurate, but from the point of view of the network guys it should be good enough to convey what you want. When everything's working and they want to look inside the zSeries cabinet for where the network kit is, *then* sit them down and fill in the gaps. ;-) > I'm also starting to appreciate how good it will be when I get z/VM v4.3 and > can use the broadcast ability of its QDIO guest LANs.

The ARP "simulation" that the Guest LAN code provides makes a Guest LAN look enough like Crashernet that most applications work just fine. Cheers, Vic Cross
