Operating system clustering is one of the major and popular high availability mechanism in system infrastructure products. Advantage of the os clustering is it can identify the application level failure.
As a systems administrators most of the time we may need to work with MS windows failover clusters. Most of the file servers and SQL clusters are depend on this failover cluster technology. Most of the situation one of the main requirement is this failover cluster is shared lus/disk. Earlier most of the time we sued to have minimum two physical servers for this cluster operation which is directly connect to SAN device(Shared storage). But to get the benefits of virtualization platform and reduce the cost , now we have to use same cluster features on top of the virtualization platform.
