Interconnect Adapters
Ethernet adapters and switches are supported as interconnects in ProLiant clusters.
Either 10-Mb/sec or 100-Mb/sec Ethernet may be used.
NOTE: For a list of supported interconnect adapters, see the Microsoft Windows NT,
Windows 2000 Advanced Server, Windows 2000 Datacenter Server, and Microsoft cluster
software compatibility list available from the Microsoft website at www.microsoft.com. Be sure
that the adapter you choose is on the list.
The Ethernet adapters can be physically connected with an Ethernet crossover cable
(direct connection) or through an Ethernet hub.
NOTE: An Ethernet crossover cable is provided in the HA/F500 Basic and Enhanced Cluster
Kits. For the Microsoft Datacenter configuration using more than two nodes, an Ethernet hub is
required.
Ethernet Direct Connection
A direct Ethernet connection uses only three components:
• Two interconnect adapters
• One Ethernet crossover cable
This solution is inexpensive, easy to install, and easy to troubleshoot. It also
minimizes the potential single points of failure.
Connecting interconnect adapters directly to each other requires a special cable. If
Ethernet is used, an Ethernet crossover cable (included in the ProLiant Cluster
HA/F500 Cluster Kit) must be used.
If the Ethernet Direct Connection cable supplied with your kit is used and
Windows 2000 is installed, the interconnect network may not show up during the
cluster installation. This is because the connection is only shown if it is currently
active at the time of installation. If the other cluster nodes are powered off at the time
you install MSCS, the connection is considered by Windows 2000 to be inactive. In
this case, define the existing public network connection as “all communications”
during the installation. After MSCS is configured on all nodes, the interconnect
network should automatically appear in the networks group in Cluster Administrator.
