1-2 Compaq Parallel Database Cluster Model PDC/O1000 for Oracle8i on Windows 2000 Administrator Guide Clusters Defined A cluster is an integration of software and hardware products that enables a set of loosely coupled servers and shared storage subsystem components to present a single system image to clients and to operate as a single system. As a cluster, the group of servers and shared storage subsystem components offers a level of availability and scalability far exceeding that obtained if each cluster node operated as a standalone server. The PDC/O1000 uses Oracle8i Parallel Server, which is a parallel database that can distribute its workload among the cluster nodes. Figure 1-1 shows a PDC/O1000 cluster that contains: I Six cluster nodes (ProLiantTM servers) I One Compaq StorageWorksTM RAID Array 4000 (RA4000 Array) or 4100 (RA4100 Array) I One Compaq StorageWorks Fibre Channel Storage Hub (Storage Hub), Compaq StorageWorks FC-AL Switch (FC-AL Switch), or Compaq StorageWorks Fibre Channel SAN Switch (Fibre Channel SAN Switch) I An Ethernet cluster interconnect I A client local area network (LAN) RA4000/4100 Array Node 5 Node 3 Node 1 Node 2 Node 4 Node 6 Storage Hub/Switch Clients Switch (Cluster Interconnect) Client LAN Figure 1-1.

Compaq Parallel Database Cluster Model PDC/O1000 for Oracle8i on Windows 2000 Administrator Guide
Clusters Defined
A cluster is an integration of software and hardware products that enables a set
of loosely coupled servers and shared storage subsystem components to
present a single system image to clients and to operate as a single system. As a
cluster, the group of servers and shared storage subsystem components offers a
level of availability and scalability far exceeding that obtained if each cluster
node operated as a standalone server.
The PDC/O1000 uses Oracle8
i
Parallel Server, which is a parallel database
that can distribute its workload among the cluster nodes.
