DAFS – Direct Access File System

Direct Access File System (DAFS) is a file-access sharing protocol that uses memory-to-memory interconnect architectures, such as VI and InfiniBand. DAFS is designed for storage area networks (SANs) to provide bulk data transfer directly between the application buffers of two machines without having to packetize the data. With DAFS an application can transfer data to and from application buffers without using the operating system, which frees up the processor and operating system for other processes and allows files to be accessed by servers using several different operating systems.
