Apart from local clusters and metro area clusters, SUSE® Linux Enterprise High Availability Extension 11 SP4 also supports geographically dispersed clusters (Geo clusters, sometimes also called multi-site clusters). That means you can have multiple, geographically dispersed sites with a local cluster each. Failover between these clusters is coordinated by a higher level entity, the so-called booth. Support for Geo clusters is available as a separate extension to Geo Clustering for SUSE Linux Enterprise High Availability Extension. For details on how to use and set up Geo clusters, refer to the Quick Start Geo Clustering for SUSE Linux Enterprise High Availability Extension. It is available from http://www.suse.com/documentation/ or in your installed system under /usr/share/doc/manual/sle-ha-geo-manuals_en/.
