TCP/UDP/IP Supported Configurations

Multiple TCP/UDP/IP HyperFabric configurations are supported to match the cost, scaling, and performance requirements of each installation.

In the previous section, “Configuration Parameters” on page 17, the maximum limits for TCP/UDP/IP enabled HyperFabric hardware configurations were outlined. In this section the TCP/UDP/IP enabled HyperFabric configurations that HP supports are explained. These recommended configurations offer an optimal mix of performance and availability for a variety of operating environments.

There are many variables that can impact HyperFabric performance. If you are considering a configuration that is beyond the scope of the following HP supported configurations, contact your HP representative.

Point-to-Point Configurations

You can interconnect large servers like the HP Superdome to run Oracle RAC 9i and enterprise resource planning applications. These applications are typically consolidated on large servers.

Point-to-point connections between servers support the performance benefits of HMP without investing in HyperFabric switches. This is a good solution in small configurations where the benefits of a switched HyperFabric cluster might not be required (see configuration A and configuration C in Figure 2-1).

If there are multiple point-to-point connections between two nodes, traffic load is balanced over those links. If one link fails, the load fails over to the remaining links (see configuration B in Figure 2-1).

Running applications using TCP/UDP/IP on a HyperFabric cluster provides major performance benefits compared to other technologies such as Ethernet. If a HyperFabric cluster is originally set up to run enterprise applications using TCP/UDP/IP and the computing environment stabilizes with a requirement for higher performance, migration to HMP is always an option.
