Introduction to Linux Clustering

2 About clusters

There are three main reasons to use clustering:

● Better performance

● Fault tolerance by high availability services.

● Optimal usage of disk resources.

Often you will hear about high performance computing solutions using Linux clusters to create

small super computers – such systems are usually referred to as “beowulf clusters”.

These systems typically run highly customised applications which are designed to run on multiple

computer systems at once, and are beyond the scope of this document.

This document will cover the following:

● High-availability clusters.

● Shared storage solutions

● Other clustering considerations.
