D Series -- PCI Express™ Adapter Cards

The Dolphin D Series products, D350, D351, D352 and D353 are low cost components for building high performance multiprocessing configurations for clustering PCs, Workstations and Servers for a variety of enterprise applications.

The D Series Cards provide extremely low latency combined with high bandwidth offering users major improvements in application performance and scalability. The D351 offers 10 Gbits/s link speed (bi-directional) that makes it an ideal platform for moving large volumes of data from system to system. For even higher bandwidth the D350 and D352 use two bi-directional links effectively doubling the throughput to an amazing 20 Gbits/s. The ultra-low 1.4 microseconds application-to-application latency reduces overhead of inter-node control messages, leading to the best possible scalability for multi-node applications. The low latency, low overhead and functional flexibility makes the D350 series an ideal choice for Real-Time embedded applications.

The superior performance of the D Series technology is achieved by taking maximum advantage of the SCI ANSI/IEEE standard with its fast point-to-point links that bypass time consuming operating system calls and protocol software overhead, required by traditional approaches.

The SCI links are hot-swappable connections. With the use of 2D/3D torus configurations or switches the SCI technology can be used to enhance fail-over performance and increase fault tolerance, ultimately reducing down-time and cost.

Dolphin offers comprehensive software support including its well proven SISCI API for a variety of operating systems and Dolphin SuperSockets™ for Linux and Windows.
