10 HP ProLiant Cluster F100 Installation Guide
Because clients desiring the full advantage of the cluster will now connect to the
cluster rather than to a specific server, configuring client connections will differ
from those for a stand-alone server. Clients will connect to virtual servers, which
are cluster groups that contain their own IP addresses.
Private or Public Interconnect
There are two types of interconnect paths:
•
•
Private interconnect
Public interconnect
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
(http://www.hp.com/servers/proliant/highavailability
).
Interconnect Adapters
Ethernet adapters and switches are supported as interconnects in ProLiant
clusters. Either a 10-Mb/s, 100-Mb/s, or 1000-Mb/s Ethernet adapter can be used.
Ethernet adapters can be connected together using an Ethernet crossover cable or
a private Ethernet hub. Both of these options provide a dedicated interconnect.
Implementing a direct Ethernet connection minimizes potential single points of
failure.
NOTE: An Ethernet crossover cable is provided in the HP ProLiant
Cluster Starter kit.
Redundant Interconnects
To reduce potential disruptions of intracluster communication, use a redundant
path over which communication can continue if the primary path is disrupted.
