DAFS

(Direct Access File System) A high-performance file sharing protocol based on the VI memory-to-memory architecture. Designed for storage area networks (SANs), DAFS provides bulk data transfer directly between the application buffers of two machines without having to packetize the data. It also allows applications to access hardware without operating system intervention. In 2001, the DAFS Collaborative group and its specification work was turned over to the SNIA and became its own working forum within that organization. See VI and SNIA.

As an early test site of DAFS technology, we've experienced the benefits first hand and have confirmed it is well-suited to handle intense transaction processing workloads.
DAFS is a perfect complement to the InfiniBand Architecture as a key technology for the data center of the future, enabling independently and massively scalable storage and compute power, high-performance file I/O, data sharing, resiliency to application server and file server failure, ease of management, and a heterogeneous, standards-based environment that promotes cost efficiency and vendor independence.
DAFS can be implemented in a number of different ways.
Our approach, therefore, has been for DAFS to closely follow NFS-v4 semantics but make fairly radical changes in how requests are represented and exchanged to improve performance using memory-to-memory networking technologies.
As mentioned above, DAFS greatly reduces the overhead normally associated with file access methods.
The members of the DAFS Collaborative believe that file mode access will become increasingly important in data center environments.
We see VI as the enabling interconnect for the next generation data centers and we see DAFS as kind of the killer app for VI.
It shows the performance advantages achieved by using DAFS storage for conventional databases and uDAPL for database clustering, as well as demonstrating that multiple products can interoperate in real application environments.
Our joint demonstration shows the ability of DAFS to take advantage of emerging standards for memory-to-memory cluster interconnect technologies such as InfiniBand and RDMA over TCP/IP.
