Virtual Network; The Virtual Network - HP NetServer AA 6200 Administrator's Manual

Virtual Network

In addition to the networking described above, the Endurance server includes a virtual network
that provides LAN-style connectivity between the CE's operating system and each IOP's
operating system. 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.
Each IOP to CE virtual network is a separate LAN. There is no direct virtual LAN between the
two IOPs. (To have this capability, we recommend that you bind a Microsoft networking
protocol, such as NetBEUI or TCP/IP to the IL adapter.) The virtual network requires no
additional hardware.
Benefits of the virtual network include:
• IOP access to CE disks
• IOP access to redirected CD-ROMs
• CE access to IOP event logs, memory dumps, and other files
• CE access to floppy drives in the IOPs
The virtual network includes the following components:
• Endurance Virtual Network Redirector (VNR)
• Endurance Virtual Network Provider (VNP)
