Computer to Switch
In this scenario shown in the following illustration, you connect your server to a switch
configured for 802.3ad link aggregation.
server1.example.com
Clients
4 x 1 Gbit/s
10 Gbit/s
The switch should have bandwidth for handling incoming traffic equal to or greater
than that of the link aggregate (logical link) you define on your server.
For example, if you create an aggregate of four 1-Gbit/s links, you should use a switch
that can handle incoming traffic (from clients) at 4 Gbit/s or more. Otherwise, the
increased bandwidth advantage in the link aggregate won’t be fully realized.
Note: For information about how to configure your switch for 802.3ad link
aggregation, see the documentation provided by the switch manufacturer.
Computer to Switch-Pair
In this scenario shown in the following illustration, you improve on the computer-
to-switch scenario by using two switches to eliminate the switch as a single point
of failure:
server1.example.com
3 x 1 Gbit/s 2 x 1 Gbit/s
