The Virtual Interface (VI) Architecture specification defines a high-bandwidth, low-latency networking architecture that was designed for creating clusters of servers and SANs (Storage Area Networks). Clustering is a technique of linking systems together in a way that makes them appear as a single system. In the past, clustering was achieved through proprietary solutions. The VI Architecture is an attempt to standardize the interface for high-performance clustering. The interface specifies logical and physical components, as well as connection setup and data transfer operations.

DAFS (Direct Access File System) uses VI Architecture as its underlying transport mechanism. DAFS is a file transfer protocol that provides a consistent view of files to a heterogeneous environment of servers that may be running different operating systems. See "DAFS (Direct Access File System)."
