Product Data

Based on Broadcom (PLX) Gen3 PCI Express switch architecture, the PXH810 host adapter includes advanced features for non-transparent bridging (NTB) and clock isolation.

For high performance application developers, the PXH810 host adapter combines 64 Gbit/s performance with less than one microsecond latency, significantly improving overall inter-system communication. Inter-processor communication benefits from the high throughput and low latency.

The PXH810 performs both Remote Direct Memory Access (RDMA) and Programmed IO (PIO) transfers, effectively supporting both large and small data packets. RDMA transfers result in efficient larger packet transfers and processor off-load. PIO transfers optimize small packet transfers at the lowest latency. The combination of RDMA and PIO creates a highly potent data transfer system.

Dolphin’s software suite takes advantage of PCI Express’ RDMA and PIO data transfer scheme. Delivering a complete deployment environment for customized and standardized applications. The suite includes a Shared-Memory Cluster Interconnect (SISCI) API as well as a TCP/IP driver and SuperSockets software. The SISCI API is a robust and powerful shared memory programming environment. The optimized TCP/IP driver and SuperSockets™ software remove traditional networking bottlenecks, allowing standard IP and sockets applications to take advantage of the high performance PCI Express interconnect without modification. The overall framework is designed for rapid development of inter-processor communication systems.

With the implementation of clock isolation, the PXH810’s signal quality is excellent. By isolating the system clock and transmitting an extremely low jitter high quality clock to downstream devices, the PXH810 offers users high signal quality and increased cable distances. The PXH810 supports PCI Express Gen3 x8 fiber optic cables up to 100 meters. The improved signal quality and fiber optic support makes the PXH810 ideal for simulation systems. The PXH810 is ideal in applications such as test and measurement equipment, medical equipment, and storage subsystem seeking high performance and data quality.

The PXH810 is carefully designed for maximum cable length and support copper cables up to 5 meters at full PCI Express Gen3 speed when connected to another PXH810 card. Fiber optics is supported up to 100 meters at full speed. More information on cables for the PXH810.

The PXH810 can be connected to the IXS600 Switch to create PCIe Gen3 networks up to 8 nodes.

The PXH810 card comes with a full license to the Dolphin eXpressWare clustering software.

The PXH812 Gen3 Adapter card does not include any software license and is recommended for IO Expansion applications.
