| Compaq Parallel Database Cluster solutions
provide high availability, scalability, and manageability for applications and data in a
business-critical environment. The Compaq Parallel Database Cluster Model PDC/O5000 for
Oracle8i Parallel Server Release 8.1.5 is a hardware and software configuration
specifically designed and tested for use with the Oracle8i Server Release 8.1.5 and
Oracle8i Parallel Server option Release 8.1.5 in support of database opportunities
such as data warehousing, web Back-end databases, custom database application development,
packaged applications and database migration from other platforms. |
|
| Description |
The Compaq Parallel Database Cluster Model
PDC/O5000 for Oracle8i Parallel Server Release 8.1.5 (PDC/O5000) allows a two to
four node cluster of Windows NT–based Compaq servers to simultaneously share a single
Oracle database. Certified for Oracle8i Server Release 8.1.5 and Oracle 8i Parallel
Server option Release 8.1.5, the PDC/O5000 cluster integrates Compaq’s unique
Operating System Dependent (OSD) software modules with Compaq’s industry standard,
fault-resilient hardware:
- Compaq ProLiant Servers (Please refer to the PDC/O5000 Certification Matrix for
supported ProLiant Server models in the PDC/O5000 configurations)
- PDC/O5000 supports the Compaq RAID Array 8000 and Enterprise Storage Array 12000
- (RA8000/ESA12000)Storage Subsystems as shared storage
- PDC/O5000 support either Ethernet or ServerNet VI dedicated cluster Interconnects
Compaq provides an Ethernet Cluster Kit or a ServerNet VI Cluster Kit for the
PDC/O5000 configurations, which contains the Compaq OSD modules for Oracle Parallel
Server, an administrator guide, and configuration posters.
The PDC/O5000 supports up to two redundant Fibre Channel Arbitrated Loops (FCAL) with
up to two Compaq StorageWorks RA8000/ESA12000 Storage Subsystems per redundant FCAL. |
|
| Maximum Availability, Minimum Cost |
| The PDC/O5000 exploits fully redundant and
optimized Windows NT Server–based Compaq ProLiant servers and other highly reliable,
industry-standard hardware. It provides significantly improved uptime and lower operating
costs than multiple single-server or proprietary database implementations. The PDC/O5000
configurations have been certified with Compaq RAID Array 8000 and Enterprise Storage
Array 12000 Storage Subsystems as shared storage. All the active components of the Compaq
RAID Array 8000 and Enterprise Storage Array 12000 Storage Subsystem are redundant and hot
replaceable which provides high system availability and No Single Point of Failure.
Additionally, Dual HBA fail-over support through the use of Secure Path software provides
redundant data paths from the host to ensure No single Point of Failure. |
|
| Increased Throughput and Simplified
Management with Oracle Software |
| All nodes within the PDC/O5000 Cluster share
a single Oracle database. Oracle Parallel Server software increases throughput to the
Oracle database by coordinating each server’s access to the data and allows the
entire cluster to be managed from a single workstation—providing increased
performance and simplified management of the database. |
| Specialized Capabilities for
Clusters |
| The PDC/O5000 utilizes either Ethernet or
ServerNet VI technology as the dedicated cluster Interconnect. The low-latency,
high-bandwidth ServerNet VI technology provides high performance for distributed lock
manager response and dedicated cluster interconnect. In addition, ServerNet VI technology
offers a low-overhead protocol stack, which offloads processor resources. These factors
allow ServerNet VI technology to meet the high-speed, low-latency requirement for an ideal
Oracle Parallel Server cluster interconnect. |
|
| Automatic online recovery |
| In the event of a node failure, the remaining
nodes can continue to have access to the database. Meanwhile, users on the failed node can
switch to another node and continue processing. The remaining nodes automatically recover
all of the transactions performed by the applications before the failure occurred,
ensuring data integrity. |
|
| Data integrity and database consistency |
| Each copy of the Oracle database is allocated
its own mirrored, multi-segment redo logs that store transactions not yet written to the
database. If a node or an Oracle copy fails, the remaining nodes use the redo log from the
failed node to bring the database back to a consistent state. |
|
| Hardware Configuration Elements |
- Compaq ProLiant Servers (two to Four nodes of the same model. Please refer to the
PDC/O5000 Certification Matrix for supported ProLiant Server models in the PDC/O5000
configurations)
- Compaq RAID Array 8000 and Enterprise Storage Array 12000 Storage Subsystems
- 100BaseTX Ethernet Interconnect or ServerNet VI Interconnect.
|
|
| Components |
| Servers |
| The PDC/O5000 supports 2 to 4 nodes of Compaq
ProLiant servers. Please refer to the PDC/O5000 Certification Matrix for supported
ProLiant Server models in the PDC/O5000 configurations. Note that all the ProLiant
servers in the PDC/O1000 or PDC/O5000 Cluster must be identically configured, including:
- All the servers within a PDC/O5000 cluster must belong to the same server model.
- Minimum memory:
Each ProLiant server in the PDC/O5000 Cluster must have a minimum of
256 MB of memory and a minimum of 512 KB L2 cache per processor.
- Balanced servers:
The servers within a PDC/O5000 cluster must be balanced. That is,
each server must have the same type and number of processors, the same amount of primary
and secondary cache, and the same type and amount of memory.
- Server mixes are currently not supported in the PDC/O5000 Cluster configuration

|
| Storage |
| The PDC/O5000 configurations have been
certified with Compaq StorageWorks RAID Array 8000 and Enterprise Storage Array 12000
Storage Subsystems as shared storage. The RA8000/ESA12000 takes advantage of the speed,
connectivity and distance characteristics of Fibre while offering data protection, high
availability, exceptional performance, multi-platform support and investment protection.
They are ideal for a broad range of mission critical applications and as shared resources
by multiple servers. The StorageWorks RA8000/ ESA12000 systems provide:
- Assuring of business continuance by protecting data integrity with high availability
features
