<p>Ever more frequently users of clusters find themselves in an interesting situation: it isn\'t the processors, communication network, or memory that is limiting their application; it is the storage system. This might force the users to checkpoint less frequently than they would like, might limit the resolution of output visualization data, or might prevent the use of out-of-core solutions needed for the largest of problems. What\'s worse, the I/O hardware in the system may indeed be adequate for the user\'s needs but may be begin used inefficiently by one of the many software layers involved.</p>
