Software support
All Dolphin PXH and MXH PCI Express NTB adapter cards support the complete eXpressWare suite of Dolphin PCI Express
Software including Dolphin SuperSockets
™
, optimized TCP/IP drivers, SmartIO and SISCI Embedded software.
Dolphin SuperSockets is a Berkeley Sockets compliant library that provides a socket latency below 1 microsecond, and
close to the wire speed streaming bandwidth for networked applications. SuperSockets
™
is currently available on Linux
and Windows. It is a 100% transparent plug-and-play solution for commercial and embedded applications.
Dolphin’s optimized TCP/IP driver enables PCI Express to be used as a traditional 10G Ethernet / 40G Ethernet
replacement such as for NFS sharing and legacy networking that does not need the low latency provided by SuperSockets.
The TCP/IP driver supports gateway functionality.
The SISCI software provides a well-defined, easy to use shared memory / reflective memory programming API for PCI
Express over cable.
The SmartIO software enables dynamic sharing of and access to PCIe devices through a PCIe fabric.
