Introduce the concept of a cluster file system
Explore available file system options
Present examples of cluster file system configurations
The compute slices in a cluster work on pieces of a larger problem. Without the ability to read data and write results, the cluster's computation is of little value. Whether the cluster is a database cluster or a scientific cluster, the compute slices need coordinated access to the shared data that is “behind” their computations. This chapter introduces some of the design issues associated with providing data to multiple compute slices in a cluster and presents some of the currently available solutions.
