Product Data

Dolphin introduced the first SCI product line in 1992. SCI products are still available and supported under a valid maintenance and support contract. Please contact Dolphin for more information. New projects are recommended to migrate to the new Dolphin Express IX product family.

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

The SCI 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 SCI 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.
