  • Add-Ons for Red Hat Enterprise Linux
    DATASHEET ADD-ONS FOR RED HAT ENTERPRISE LINUX WORKLOAD AND MISSION-CRITICAL PLATFORM ENHANCEMENTS In conjunction with Red Hat® Enterprise Linux®, Red Hat offers a portfolio of Add-Ons to extend the features of your Red Hat Enterprise Linux subscription. Add-Ons to Red Hat Enterprise Linux tailor your application environment to suit your particular computing requirements. With increased flexibility and choice, customers can deploy what they need, when they need it. ADD-ON OPTIONS FOR AVAILABILITY MANAGEMENT High Availability Add-On Red Hat’s High Availability Add-On provides on-demand failover services between nodes within a cluster, making applications highly available. The High Availability Add-On supports up to 16 nodes and may be configured for most applications that use customizable agents, as well as for virtual guests. The High Availability Add-On also includes failover support for off-the-shelf applications like Apache, MySQL, and PostgreSQL. When using the High Availability Add-On, a highly available service can fail over from one node to another with no apparent interruption to cluster clients. The High Availability Add-On also ensures data integrity when one cluster node takes over control of a service from another clus- ter node. It achieves this by promptly evicting nodes from the cluster that are deemed to be faulty using a method called “fencing” that prevents data corruption. www.redhat.com DATASHEET ADD-ONS For RED Hat ENterprise LINUX 6 Resilient Storage Add-On Red Hat’s Resilient Storage Add-On enables a shared storage or clustered file system to access the same storage device over a network.
