Starting with HP Serviceguard A.11.16, HP 9000 and Integrity servers that run HP-UX 11i v2UD2
can be configured to run in a single heterogeneous HP 9000/Integrity Serviceguard cluster.
Purpose of document
This technical whitepaper explains how to create a new cluster with both types of servers and how to
upgrade an existing HP 9000 cluster or an existing HP Integrity cluster to include both server types.
The document:
• Explains the new feature of HP Serviceguard that provides the opportunity to mix HP Integrity and
HP 9000 servers in a single HP Serviceguard cluster
– HP-UX 11i v2UD2 provides the same feature set to both HP 9000 and Integrity platforms.
– HP Serviceguard A.11.16 provides feature parity between HP9000 and Integrity systems.
– Many independent software vendors (ISVs) provide their software in two versions, one for HP
9000 and the other for HP Integrity servers.
• Informs the reader about configuration rules and best practices in regards to mixed clusters for:
– Cluster hardware
– HP-UX 11i v2UD2 and subsequent releases
– nPars and vPars
– HP Serviceguard A.11.16 and subsequent releases
– Protected applications
– Rules when mixing architectures with a single application
– Rules when mixing architectures with multiple applications
– Rules when mixing architectures for multi-tier applications
