General Network Considerations

Preboot Execution Environment
The preboot execution environment (PXE) allows a system to boot from an
operating system image over the network. By definition, PXE is invoked before an
operating system is loaded, so there is no opportunity for the QLASP intermediate
driver to load and enable a team. As a result, teaming is not supported as a PXE
client, though a physical adapter that participates in a team when the operating
system is loaded may be used as a PXE client. Whereas a teamed adapter
cannot be used as a PXE client, it can be used for a PXE server, which provides
operating system images to PXE clients using a combination of dynamic host
control protocol (DHCP) and the trivial file transfer protocol (TFTP). Both of these
protocols operate over IP and are supported by all teaming modes.
General Network Considerations
When configuring teaming, consider this network information:
Teaming with Microsoft Virtual Server 2005
Teaming with Hubs (for troubleshooting purposes only)
QLASP Teaming with Microsoft NLB
Teaming with Microsoft Virtual Server 2005
The only supported QLASP team configuration when using Microsoft Virtual
Server 2005 is with a QLASP Smart Load Balancing team-type consisting of a
single primary Cavium adapter and a standby Cavium adapter. Make sure to
unbind or deselect “Virtual Machine Network Services” from each team member
prior to creating a team and prior to creating virtual networks with Microsoft Virtual
Server. Additionally, a virtual network should be created in this software and
subsequently bound to the virtual adapter created by a team. Directly binding a
guest operating system to a team virtual adapter may not render the results you
want.
NOTE
At the time of publication, Windows Server 2008 is not a supported
operating system for Microsoft Virtual Server 2005; thus, teaming may not
function as expected with this combination.
