−	~~= Red Hat Cluster Suite Introduction =~~
−	Red Hat Cluster Suite (RHCS) is an integrated set of software components that can be deployed in a variety of configurations to suit your needs for performance, high-availability, load balancing, scalability, file sharing, and economy.
−
−	~~== RHCS consists of the following major components ==~~
−	* Cluster infrastructure — Provides fundamental functions for nodes to work together as a cluster: configuration-file management, membership management, lock management, and fencing.
−	* High-availability Service Management — Provides failover of services from one cluster node to another in case a node becomes inoperative.
−	* Cluster administration tools — Configuration and management tools for setting up, configuring, and managing a Red Hat cluster. The tools are for use with the Cluster Chapter Infrastructure components, the High-availability and Service Management components, and storage.
−	* Linux Virtual Server (LVS) — Routing software that provides IP-Load-balancing. LVS runs in a pair of redundant servers that distributes client requests evenly to real servers that are behind the LVS servers.
−	~~== Additional Cluster Components ==~~
−	~~You can supplement Red Hat Cluster Suite with the following components, which are part of an optional package (and not part of Red Hat Cluster Suite):~~
−	* Red Hat GFS (Global File System) — Provides a cluster file system for use with Red Hat Cluster Suite. GFS allows multiple nodes to share storage at a block level as if the storage were connected locally to each cluster node.
−	* Cluster Logical Volume Manager (CLVM) — Provides volume management of cluster storage.
−	* Global Network Block Device (GNBD) — An ancillary component of GFS that exports block-level storage to Ethernet. This is an economical way to make block-level storage available to Red Hat GFS.
−	~~= OSCAR =~~
−
−	~~== Diskless nodes ==~~
−	~~See [http://web.mst.edu/~vojtat/pegasus/home.htm Pegasus homepage] for ideas to implement a diskless Linux cluster.~~
