3.6.1 Clustering

A cluster is two or more computers (known as nodes) that work together to
provide a solution. The idea behind clusters is to join the computing powers of
the nodes involved to provide higher scalability, more combined computing
power, or to build in redundancy to provide higher availability. The sharing of data
between the nodes of a cluster through a common file system is almost always a
requirement.

If you are implementing Microsoft Cluster Service (MSCS) check the Microsoft
Cluster Service Hardware Compatibility List (HCL) to confirm that hardware,
drivers, and firmware have been Microsoft Certified. The HCL can be found at:
