Chapter 2 HP NetServer AA Overview Virtual Network In addition to the networking described above, the server includes a virtual network that provides LAN-style connectivity between the CE and each IOP. This connectivity is independent of any public (redirected) or private (IOP) network adapters. Within this virtual network, the IOPs and CE appear as three interconnected nodes, as shown in Figure 2-2. Figure 2-2 The Virtual Network Each IOP to CE virtual network is a separate LAN. There is no direct virtual LAN between the two IOPs. (To have this capability, HP recommends that you install Enhanced IL networking.) The virtual network requires no additional hardware. Benefits of the virtual network include: • IOP access to CE disks while online • IOP access to redirected floppy drives and CD-ROMs • CE access to IOP event logs, memory dumps, and other files The virtual network includes the following components: • Virtual Network Redirector (VNR) • Virtual Network Provider (VNP) Network transports are bound to VNR and VNP just as they would be bound to any standard Network Interface Card. Ethernet addresses for all virtual adapters are automatically assigned and are based on the Ethernet Vendor ID. 14
