1. Define the guest LAN (CP DEFINE LAN) 2. Within each guest that will use the guest LAN, define the NIC (CP DEFINE NIC) 3. Connect each guest's NIC to the guest LAN (CP COUPLE) Guest LANs come in two flavors: OSA Express (QDIO) and zSeries HiperSockets. Each guest LAN can be different. As David Boyes said, treat each guest LAN as you would a real LAN, and treat the virtual router as part of your WAN infrastructure, with all the rights, privileges, and responsibilities of an external router. > what speed can the nic reach? That isn't really a useful measurement, Alex, as virtual NICs are simulated within CP, so their speed depends on the speed of the processor, the number of processors, and the load on the system. As CPUs get faster, so do guest LANs! > and, what about firewall inside the z800, its a good idea to keep that > load inside vm or its best to keep it in another server outside the z? This is determined by network design. If you have guest LANs that need to talk to each other, but a firewall is required, then you might find it better to put firewall in a guest so that real network I/O is not required. YMMV.
