Overview

HyperFabric is a HP high-speed, packet-based interconnect for node-to-node

communications. HyperFabric provides higher speed, lower network latency and less

CPU usage than other industry standard protocols (e.g. Fibre Channel and Gigabit

Ethernet). Instead of using a traditional bus based technology, HyperFabric is built

around switched fabric architecture, providing the bandwidth necessary for high speed

data transfer. This clustering solution delivers the performance, scalability and high

availability required by:

• Parallel Database Clusters:

Oracle 9i Real Application Clusters (RAC)

Oracle 8i Parallel Servers (OPS)

• Parallel Computing Clusters

• Client/Server Architecture Interconnects (for example, SAP)

• Multi-Server Batch Applications (for example, SAS Systems)

• Enterprise Resource Planning (ERP)

• Technical Computing Clusters

• Open View Data Protector (earlier known as Omniback)

• Network Backup

• Data Center Network Consolidation

• E-services

Notice of non support for Oracle 10g RAC

HyperFabric product suite was designed to optimize performance of Oracle 9i RAC

database running on HP-UX clusters. With the industry moving to standards-based

networking technologies for database clustering solutions, HP and Oracle have worked

together to optimize features and performance of Oracle 10g RAC database with

standards-based interconnect technologies including Gigabit Ethernet, 10Gigabit

Ethernet and Inﬁniband.

To align with the market trend for standards-based interconnects, Oracle 10g RAC

database is not currently supported on conﬁgurations consisting of HyperFabric product

suite and it will not be supported in the future either. As a result, customers must switch

to Gigabit Ethernet, 10Gigabit Ethernet or Inﬁniband technology if they plan to use

Oracle 10g RAC.

Please note that conﬁgurations comprising HyperFabric and Oracle 9i continue to be

supported.
