SCO HA Clusters is a high availability clustering solution for any size business requiring high levels of application and data availability. Businesses today are increasingly dependent on large servers to support their information processing needs, and any interruption in these services can be enormously expensive. HA Clusters increases the overall availability of applications and critical data by connecting multiple servers together as nodes within a single high-availability fail-over cluster. Applications do not need to be aware of the operation of the cluster, and all nodes within the cluster may be used simultaneously for processing.
HA Clusters extends the high performance, reliability, availability and scalability (RAS) characteristics of all the SCO UNIX server operating system editions to provide continuous monitoring and fault detection of applications, resources, and entire nodes. In the event of a failure, automated recovery scripts are initiated to enable rapid or transparent restoration of services, depending on the application. Recovery actions include the unattended restart of resources, switching to alternative data paths, or migrating services to other systems within the cluster. Once a failed node has been replaced or repaired it may be returned to service in the active cluster. A graphical Configuration Manager provides a single point of control for all HA Clusters services.
HA Clusters is ideal for increasing the availability of business-critical applications such as transaction processing, database, email, Web, and file and print services. SCO HA Clusters is a flexible, nonstop, automated high availability clustering solution that protects valuable data and applications running on SCO UNIX servers against both unplanned and planned downtime. Businesses are kept up and running through continuous server monitoring and immediate, automated failover to an alternate server. With intelligent features that continuously seek out potential problems at the hardware, software and network levels, SCO HA Clusters minimizes downtime to only seconds or minutes in order to save businesses time and money and boost productivity.
