The Red Hat Cluster Manager software was originally based on the open source Kimberlite (http://oss.missioncriticallinux.com/kimberlite/) cluster project, which was developed by Mission Critical Linux, Inc.

Subsequent to its inception based on Kimberlite, developers at Red Hat have made a large number of enhancements and modifications. The following is a non-comprehensive list highlighting some of these enhancements.

- Packaging and integration into the Red Hat installation paradigm to simplify the end user's experience.

- Addition of support for multiple cluster members.

- Addition of support for high availability NFS services.

- Addition of support for high availability Samba services.

- Addition of the Cluster Configuration Tool, a graphical configuration tool.

- Addition of the Cluster Status Tool, a graphical monitoring and administration tool.

- Addition of support for failover domains.

- Addition of support for Red Hat GFS, including the GFS Setup Druid and the LOCK_GULM fencing driver.

- Addition of support for using watchdog timers as a data integrity provision.

- Addition of service monitoring which automatically restart a failed application.

- Rewrite of the service manager to facilitate additional cluster-wide operations.

- A set of miscellaneous bug fixes.
