HA Clusters Quick Links
OverviewHigh-Availability (HA) Clusters are a class of tightly-coupled distributed systems that provide high availability of services through hardware and software monitoring and hardware redundancy. HA Clusters are often closely associated with the underlying operating system, and in many cases can be considered extensions of the OS. The focus of this community is implementations, ideas, innovations, and research around high-availability clusters on the OpenSolaris platform. This scope includes, but is not limited to, areas such as core technologies (eg. membership, quorum, filesystems), APIs, system administration, application support code (agents), and test frameworks. Although the focus is on clusters for high-availability, as opposed to HPC clusters, grids, or other cluster technologies, we recognize that there is often overlap between the technologies for different kinds of clusters, and will not discourage fruitful conversations and projects as long as they relate to high availability. The HA Clusters community is the home of Open High Availability Cluster, the open-source code base of Solaris Cluster, a high availability (HA) clustering solution from Sun Microsystems, Inc.
