HP Serviceguard Cluster Configuration for HP-UX 11i or Linux Partitioned Systems
HP Serviceguard provides an infrastructure for the design and implementation of highly available HP-UX or Linux clusters that can quickly restore mission-critical application services after hardware or software failures. To achieve the highest level of availability, clusters must be configured to eliminate all single points of failure (SPOFs). This requires a careful analysis of the hardware and software infrastructure used to build the cluster. Partitioning technologies such as Superdome nPartitions, available on HP-UX 11i v2 or Linux, the HP-UX Virtual Partitions (vPars) and HP Integrity Virtual Machines (Integrity VM) present some unique considerations when utilizing them within a Serviceguard configuration. This paper discusses these considerations.
