High Availability Add-On for Red Hat Enterprise Linux on HP ProLiant Servers: References and Best Practices

HP CLX and RHEL stretched clusters

Although RHEL5 and RHEL6 clusters generally support HP’s Continuous Access storage replication

technology, Red Hat does not directly support HP's associated Cluster Extension (CLX) software in

stretched cluster configurations. However, HP provides direct support for CLX in selected stretched

cluster configurations, and works with Red Hat to assure interoperability and to resolve RHEL cluster

support issues should they arise.

All RHEL cluster deployments with CLX require an architecture review performed jointly by HP and Red

Hat. All questions regarding architectural concepts, stretched cluster configurations, architecture

reviews, and support issues should be directed to HP through your HP sales or support contacts, and

should not be directed to Red Hat.
