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.
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.
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.
