Processor Type
Processor Type
The processing power of the Integrity NonStop NS-series servers (through which a
message is transmitted) determines throughput if there are no bottlenecks in the other
components of the network. The relative processor power factors are a good starting
point for estimating Expand line-handler process performance limits.
Process location and load balancing within a system can also have a major impact on
network performance. The same type of analysis used for any other NonStop™
process can also be applied to Expand line-handler processes.
NAM Process Configuration
Configuring an Expand-over-NAM line-handler process and a NAM process in the
same processor is more processor-efficient than configuring these processes in
separate processors.
However, when an Expand line-handler process and the NAM process it uses are in
the same processor, total throughput is limited. Because you can configure an Expand
line-handler process and its associated NAM process in separate processors, you can
achieve a combined processor usage of greater than 100 percent for this type of
Expand connection.
For more information on the Expand-over-NAM line-handler process configuration, see
Section 10, Configuring Expand-Over-X.25 Lines and Section 13, Configuring Multi-
Line Paths.
Expand-Over-IP Configuration
Expand-over-IP line-handler processes use a NonStop TCP/IP process to provide
TCP/IP connectivity. The NonStop TCP/IP process associated with the Expand-over-IP
line-handler process must be configured in the same processor pair as the Expand-
over-IP line-handler process.
With NonStop TCP/IPv6, the Expand line-handler process must be configured in a
processor where a TCP6MON process is running; this usually yields a free choice of
processor. It is not necessary nor beneficial in any way to co-locate the Expand line-
handler process and the TCP6SAM process.
For more information on the Expand-over-IP line-handler process configuration, see
Section
8, Configuring Expand-Over-IP Lines.
Note. In general, the newer processor types are faster than the older processor types. Contact
your HP representative for detailed performance information regarding a specific type of HP
processor.
