The Linux-HA (High-Availability Linux) project provides a high-availability solution for Linux, FreeBSD, OpenBSD, Solaris and Mac OS X which promotes reliability, availability, and serviceability (RAS). [1] The project's main software product is Heartbeat, a GPL-licensed portable cluster management program for high-availability clustering. Its ...
High-availability clusters (also known as HA clusters, fail-over clusters) are groups of computers that support server applications that can be reliably utilized with a minimum amount of down-time. They operate by using high availability software to harness redundant computers in groups or clusters that provide continued service when system ...

The Red Hat Cluster Suite (RHCS) includes software to create a high availability and load balancing cluster. Both can be used on the same system although this use case is unlikely. Both products, the High Availability Add-On and Load Balancer Add-On, are based on open-source community projects. Red Hat Cluster developers contribute code ...
SIOS LifeKeeper (formerly known as SteelEye LifeKeeper) is a high-availability cluster software, for Linux computer systems. It provides application cluster capabilities for nonstop operation and disaster recovery to systems running databases, file sharing on a network, electronic commerce websites, ERP systems or other applications requiring nonstop operation
Pacemaker is an open-source high availability resource manager software used on computer clusters since 2004. Until about 2007, it was part of the Linux-HA project, then was split out to be its own project. [3] It implements several APIs for controlling resources, but its preferred API for this purpose is the Open Cluster Framework resource ...
Open Cluster Framework (OCF) is a set of standards for computer clustering. The project started as a working group of the Free Standards Group , now part of the Linux Foundation . Original supporters included several computing companies and groups, including Compaq , Conectiva , IBM , Linux-HA , MSC Software , the Open Source Development Lab ...
Conventional computer cluster systems typically use some sort of shared storage for data being used by cluster resources. This approach has a number of disadvantages, which DRBD may help offset: Shared storage resources must typically be accessed over a storage area network or on a network attached storage server, which creates some overhead in ...
