Chapter 1. Red Hat Cluster Suite Overview 3

• 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.

• Cluster administration tools — Conﬁguration and management tools for setting up, con-

ﬁguring, and managing a Red Hat cluster. The tools are for use with the Cluster Infras-

tructure components and with the High-availability and Service Management compo-

nents. You can conﬁgure and manage other Red Hat Cluster Suite components through

tools for those components.

• 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.
