Installing an AlphaServer ES45 into a
TruCluster Server Configuration
3.1 Preparing the AlphaServer ES45 for a TruCluster Server
Configuration
The AlphaServer ES45 has PCI slot restrictions that must be adhered to,
but otherwise, creating a cluster of ES45 systems, or adding an ES45 system
to an existing cluster, is basically the same as any AlphaServer system
supported in a TruCluster Server configuration.
Cluster hardware installation can be divided into two steps:
• Installing and configuring the cluster interconnect
• Installing and configuring shared storage
______________________ Note _______________________
If you plan to add an ES45 with dual Memory Channel adapters
(which must be jumpered for 128 MB) into an existing cluster
with Memory Channel adapters jumpered for 512 MB, you must
reset the jumpers on the existing Memory Channel adapters to
128 MB before booting the ES45 into the cluster.
The following sections provide information about installing an AlphaServer
ES45 into a TruCluster Server configuration.
3.2 Installing and Configuring the Cluster Interconnect
A TruCluster Server configuration requires a cluster interconnect connecting
all cluster members together. The cluster connect can be provided by
Memory Channel (Memory Channel 2) hardware or a private local area
network (LAN):
• To install MC2 hardware as the cluster interconnect, review the
restrictions listed in Section 2.2.3 and see the chapter about setting
