Task Force on Network Storage Architecture: Coupling advanced data movement to advanced storage David S. Greenberg - Sandia National Labs, Albuquerque, NM Storage architectures are poised to take a significant leap forward. The "Unix file system with processor-attached disk and tape" model will be replaced with a "data management systems and network-attached storage" view. It is important, as this critical change occurs, that advances in parallel data transfer be incorporated. In particular, the parallel computing community is moving beyond explicit OS buffering, sending, receiving, and unbuffering to protocols in which data is moved directly to or from user data structures. Future I/O systems will be able to simplify flow control and minimize buffer usage if all elements including the network-attached devices have enough power to implement these direct protocols.
