Planning Cluster Interconnect and Client LAN
Components
PDC/O5000 clusters running Oracle8i Parallel Server can use a redundant
Ethernet cluster interconnect. A redundant cluster interconnect is required
because it provides fault tolerance along the cluster interconnect paths.
Planning an Ethernet Cluster Interconnect
NOTE: Refer to the technical white paper Supported Ethernet Interconnects for Compaq
Parallel Database Clusters Using Oracle Parallel Server for detailed information about
configuring redundant Ethernet cluster interconnects. This document is available at
www.compaq.com/support/techpubs/whitepapers
Before installing the Ethernet cluster interconnect in a PDC/O5000 cluster,
review these planning considerations:
I
Whether to use two Ethernet switches or two Ethernet hubs for the
cluster interconnect. If your cluster will contain or grow to three or more
nodes, you must use two Ethernet switches.
I
Whether to use two dual-port Ethernet adapters in each node that will
connect to both the cluster interconnect and the client LAN or to use
separate single-port adapters for the Ethernet cluster interconnect and
the client LAN.
Planning the Client LAN
Every client/server application requires a local area network (LAN) over
which client machines and servers communicate. In the case of a cluster, the
hardware components of the client LAN are no different than in a stand-alone
server configuration.
In keeping with the redundant architecture of the cluster interconnect, you may
choose to install a redundant client LAN, with redundant Ethernet adapters and
redundant Ethernet switches or hubs.
