Clients
How do clients know the
server has two or more
IP addresses?
Which IP address represents
the server for
DNS/NetBIOS/etc.?
Server has redundant path
for outgoing traffic.
From the server’s IP perspective,
either adapter provides access
to the network.
In contrast, Network Adapter Teaming provides transparent redundancy for both the server’s
outbound connectivity and all inbound client connectivity (refer to Figure 3-3). Full transparent
redundancy for the IP address is provided by teaming. A network port failure (or cable failure,
or upstream switch failure, etc.) in the server with teaming as identified in Figure 3-1, will be
completely transparent to the server’s protocol stack and to the server’s clients. Any client
connections to the server using the server’s IP address (bound to the virtual network adapter
interface rather than the network adapter hardware) remain active and unaware that an individual
network port failed.
