Introduction
The Red Hat Cluster Suite is a collection of technologies working together to provide
data integrity and the ability to maintain application availability in the event of a failure.
Administrators can deploy enterprise cluster solutions using a combination of hardware
redundancy along with the failover and load-balancing technologies in Red Hat Cluster
Suite.
Red Hat Cluster Manager is a high-availability cluster solution specifically suited for
database applications, network file servers, and World Wide Web (Web) servers with dy-
namic content. A Red Hat Cluster Manager system features data integrity and applica-
tion availability using redundant hardware, shared disk storage, power management, robust
cluster communication, and robust application failover mechanisms.
Administrators can also deploy highly available applications services using Piranha, a load-
balancing and advanced routing cluster solution based on Linux Virtual Server (LVS) tech-
nology. Using Piranha, administrators can build highly available e-commerce sites that
feature complete data integrity and service availability, in addition to load balancing capa-
bilities. Refer to Part II Configuring a Linux Virtual Server Cluster for more information.
