Server-to-Server (Back-to-Back)
Figure 3-4 (page 25) shows a sample server-to-server configuration. You create server-to-server
aggregations by directly connecting the physical ports in one server's link aggregation to the
physical ports in the other server's link aggregation. This configuration has the following
characteristics:
• It needs many TCP/UDP client connections between the servers in order for load balancing
to be effective. Therefore, use the HP APA TCP/UDP port load-balancing algorithm.
• Depending on the network traffic bandwidth requirements, use two to eight 100BT interfaces
or two to eight Gigabit interfaces in an PAgP or MANUAL link aggregation. With LACP,
you can use up to 32 interfaces in the link aggregation. This enables bandwidth scalability
as network loads increase as the organization grows.
