RedHat Cluster Suite
Originally written by
- A part of the RedHat enterprise server Linux distributions (can be used
independently too, it seems).
- Supports active-passive and probably also active-active clusters (e.g.
when used on top of RedHat's GFS shared file-system).
- Very simple - does no proper resource monitoring.
- Has a simple GUI to configure it.
- Supports I/O fencing using the STONITH mechanism.
- Works with any kind of block device.
