TCP/UDP Port-based Load Balancing
The TCP/UDP Port-based algorithm may also be used to connect two collaborating HP
9000 servers with APA. This algorithm has the same benefits as the CPU-based
algorithm except it does not require the use of processor affinity in order to ensure
predictable results. The TCP/UDP source and destination port numbers are hashed to
determine which port each packet should be transmitted on. When non-IP traffic is
transmitted, the algorithm defaults back to MAC-based distribution.
This is the recommended algorithm when deploying APA in a Server-to-Server
environment.
Typical Customer Configurations
Mergers, acquisitions, and reorganizations: Each places a unique demand on enterprise
data centers and the best solution is one that can address all of these needs. This is
exactly what APA is designed to do!
