VMware Bridged Networks: Protecting the Entire Network from System Faults

Configuring VMware bridged networking allows for teaming network adapters in order to increase its fault tolerance level.  The idea behind network bridge teaming is to secure the network in cases where an adapter suffers failure.  In this instance, when an adapter fails to function, traffic on the server and the entire network can still run and continue to function because of the bridging technique.  This is essentially a double wall protection for systems running several virtual networks.

Fault tolerance can also be enhanced by leaving the original configuration of bridging typical to any Windows based platform.  Automatic bridging is automatically loaded on a network with several adapters.  The user however needs to manually configure and select which should be the primary and secondary adapters.  In this way, when a crash or a glitch happens on the primary network, the system will automatically bridge all activities on the secondary route eliminating the danger of network paralysis. 

System administrators must thoroughly understand the network teaming configuration of the host machine before applying bridges to the virtual machines.  Applying teamed networks on virtual machines involves binding the entire VMware bridging protocols to the teamed network.  The individual virtual machines on the other hand should be released from the network interface cards of the host.  This is to ensure that no conflict can occur on networked virtual machines.  Information on how to configure these settings can be found on the host network configuration systems which include the methods on setting up the windows host settings.
