ServerNet Clusters Coexisting With ATM or IP
Networks
Interoperability is supported between a ServerNet cluster and an ATM network using
ATM adapters or between a ServerNet cluster and an IP network using Ethernet, Fast
Ethernet, Gigabit Ethernet, or ATM adapters. These technologies allow the following:
•
Connection over distances greater than five kilometers
•
Use of TCP for internode communications (the IP technology)
•
Reduction of line costs
•
Interoperability between NonStop K-series servers, S-series servers, and Integrity
NonStop servers (the IP technology)
The topics addressed in this subsection include:
•
Considerations for ServerNet Clusters Coexisting With ATM or IP on page 4-3
•
Examples of ServerNet Clusters Coexisting With ATM or IP on page 4-4
For information about IP and ATM adapters, see the following manuals:
TCP/IPv6 Configuration and Management Manual
TCP/IP (Parallel Library) Configuration and Management Manual

ATM Configuration and Management Manual
Considerations for ServerNet Clusters Coexisting With ATM
or IP
•
Traffic can be distributed in a balanced fashion over the ATM or IP lines by
appropriately configuring the time factors (TFs). For information about configuring
time factors, refer to Routing and Time Factors on page 17-21.
•
Be careful when mixing these technologies to ensure a fault-tolerant topology and
to prevent bottlenecks at the inter-technology connection points.
•
If you want to expand your ServerNet cluster by adding nodes, HP recommends
that you use the guided procedure. To add a node by using the OSM Service
Connection, log onto the system being added, select the Configure a ServerNet
Node action for the System object, and perform the action. A guided procedure is
launched, with online help available to assist you in performing the procedure.
