Direct Access File System
Last modified: Friday, May 12, 2006
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.
DAFS Collaborative Completes New File Access Protocol The DAFS protocol is a high-performance file access technology that DAFS Collaborative says will greatly improve the performance, scalability, and reliability of Internet and enterprise applications in clustered data center environments.
