204. VI Architecture (Virtual Interface Architecture) - Term
What is: 204. VI Architecture (Virtual Interface Architecture)
Description: A consortium established in 1996 to study methods for lowering the excessive overhead of traditional I/O software for data center networks. The VI Architecture standard defines the VI Architecture, an API specification for direct communication among distributed applications. This API specifies how an agent initiates the connection between two nodes. After initiation, a direct connection between user agent memory, or virtual interface protocol layer, and the hardware allows a direct memory copy between two nodes using the VI communication channel. These communications can be performed directly by memory-mapped I/O or by using additional layers to adapt from the VI structure to internal data formats.
