Choosing a Mode of Operation
VNET Switch Mode
When the adapter is operating in this mode, multiple LAN segments
are registered with the NOS as a single subnet, called a VNET.
VNETs are multisegment virtual subnets.
VNETs are made possible by a layer of virtual network software
that binds to multiple instances of the adapter LAN driver and
registers them with the NOS as a single subnet. Multiple
PeerMaster adapters can be configured to interoperate in various
ways, such as:
Traditional subnets
One large VNET
Multiple independent VNETs
Any combination of VNETs and traditional subnets
All physical segments within a VNET are configured to the same
network number. Cross-segment traffic within a VNET is switched
by your adapter instead of by your server, allowing the server to be
more productive. The server is shielded from the task of routing,
which enables the creation of powerful switched, multi-segment,
high-bandwidth workgroups or departments. External
internetworking devices are not required to provide communication
between segments with a VNET.
Following are guidelines for using the VNET Switch mode:
Do not externally join (using bridges, switches, or concentrators)
ports of adapters that comprise a VNET.
You can configure as many nodes as you need; the adapter
places no limit on the number of nodes per port.
Ensure that all ports in a VNET are bound to the protocol (by
way of VNET) with a common network number.
