Overview of the HP ProLiant Cluster F100 11
HP recommends configuring the client LAN as a backup path for intracluster
communication. This provides a secondary path for the cluster heartbeat in case
the dedicated primary path for intracluster communications fails. This is
configured when installing the cluster software, or it can be added later using the
MSCS Cluster Administrator.
HP offers a feature that configures two HP Ethernet adapters (or two ports on a
single adapter) so that one is a hot backup for the other. There are two ways to
achieve this configuration, called NIC Teaming, and the method you choose
depends on the hardware. One way is through the use of the Redundant NIC
Utility available on all HP 10/100/1000 Fast Ethernet products. The other option
is through the use of the Network Fault Tolerance feature designed to operate
with the HP 10/100/1000 Intel® silicon-based NICs.
For more information on recommended interconnect strategies, refer to the white
paper, Best Practices Checklist—Increasing Network Fault Tolerance in a
Microsoft® Windows® Server 2003, Enterprise Edition High Availability Server
Cluster, available from the ProLiant High Availability website

Cables
Three general categories of cables are used for the F100 cluster:
•
•
•
Server to storage
Cluster interconnect
Network interconnect
Server to Storage
Shortwave (multi-mode) fiber optic cables are used to connect the servers,
switches or Fibre Channel storage hubs, and storage systems in a Fibre Channel
configuration.
Cluster Interconnect
When Ethernet cluster interconnect cables are used with Ethernet NICs to
implement the interconnect, there are three options:
