Dolphin Interconnect Solutions is a manufacturer of high speed data communication systems, located in Oslo, Norway (headquarters) and Woodsville, New Hampshire, USA.

The technology of Dolphin was based on development work at Norsk Data during the late 1980s. Dolphin Interconnect Solutions was founded in 1992 as a spin-off from Dolphin Server Technology which was in turn a spin-off from Norsk Data in 1989. Dolphin Interconnect Solutions develops technology for low latency, very high speed communication, between servers and/or embedded computer systems.


Dolphin started out continuing the development of a line of Scalable Coherent Interface (SCI) products from Norsk Data, by implementing customer-specific technology, as well as providing Peripheral Component Interconnect (PCI) and later PCIe boards for commodity and High-performance computing systems. Dolphin SCI products are available under the Dolphin Express SCI label.

The StarFabric product line was added to the Dolphin interconnect portfolio through the acquisition of StarGen Inc. StarFabric provides a PCI-based interconnect running over standard Ethernet Category 5 cables.

Similarly, the Dolphin Express DX product line introduced in 2006 was also acquired from Stargen. DX was based on the ASI standard and implements a PCI Express Gen1 switched-topology technology supporting both host to host communication and host to IO Expansion solutions over a single cable connection.

The Dolphin Express IX product line introduced in 2010 is based on PCI Express Gen2 and Gen3 chipsets from Integrated Device Technology. The Dolphin Express PX product line introduced in 2016 is based on PCI Express Gen3 chipsets from Broadcom. IX and PX implements a PCIe-native switched-topology technology.

The SISCI application programming interface (API), was developed for the shared memory SCI hardware. With the introduction of the PX, IX and DX-line of products, the API was expanded to support features like reflective memory/multicast and PCIe peer to peer communication.

SuperSockets is a software infrastructure for Dolphin Express providing a very low latency, high throughput implementation of the Berkeley sockets and Winsock APIs.
