Planning the Fabric

TCP/UDP/IP

Chapter 2 21

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.
