The DAFS Database Accelerator, currently in customer beta test sites in the United States and Europe, is expected to be generally available within 30 days.
DAFS (Direct Access File System) is a file-access protocol that utilizes standard RDMA transports such as the Virtual Interface (VI) and InfiniBand for high performance storage access in data center environments.
David Dale is an industry evangelist at Network Appliance (Waltham, MA) and a co-chair of the DAFS
DAFS addresses this by providing flow control directly within the protocol.
DAFS pre-allocates response cache space on a per-session basis, with limited space per session.
The first method shown is a user library that implements the DAFS protocol.
To maximize performance, the DAFS library exports an API that gives the user application explicit control over NIC DMA access to its address space.
Collaborative encourages broad industry participation.
NetApp DAFS Database Accelerator uses virtual interface (VI) technology over a Gigabit Ethernet interconnect, enabling Network Appliance and Sybase enterprise customers to support larger workloads on existing hardware in high-performance database deployments.
By helping to reduce database server overhead, the combination of DAFS and Sybase ASE offers customers in Sun(R) Solaris(TM) environments a clear performance advantage," said Dr.
is a file access protocol that utilizes remote direct memory access (RDMA) transport mechanisms, such as the Virtual Interface (VI) architecture, to accelerate the movement of data between systems, avoiding operating system overhead.
The chief customer benefit from both DAFS
and business application acceleration solutions is increased productivity through increased performance, at the data center where IT demands are incredibly rigorous, and at remote offices and branch offices, where geographically distributed employees need instant access to data center information that drives their business decisions.
