Windows Server moves the teaming functionality from the hardware layer to the OS layer. This process eliminates the switches as failure points, too.
If you assign a single IP address configuration to a NIC team, you can connect the NICs to multiple physical or virtual switches. One connection to one switch is a single point of failure.
NIC teaming aggregates two or more NICs, increasing the bandwidth. Network bandwidth is a connection's maximum total data transfer rate. NIC teaming can help in the following ways: You can install another NIC, but this also adds a second identity to the server in the form of an IP address. The problem is the server only has one way of physically connecting to the network. It's simple enough to provide another network cable, and your organization might already have multiple switches. The OS sees this configuration and uses bandwidth based on the limitations of the slowest component.Īny one of the pieces is a single point of failure. A typical network connection for a server consists of a NIC connected to one port in a single switch by a twisted-pair network cable.
