All the storage for whatever applications they are running is held externally in a pair of disk arrays or a SAN, this allows either machine to act as master node and control the data. Should that machine experience some major problem, the other machine takes control of the cluster and the data.
There are 2 main configurations active/active and active/passive.
In A/A each machine runs some of the services normally, but takes everything if required. Clearly the machines must be capable of running the whole load.
In A/P mode, one machine runs the load and the other is idle until required.
More advanced clusters use more than 2 servers or are split across datacentres.
Clustering and resilience generally is a trade between cost and risk.
