PXH830 PCIe NTB Host Adapter

Gen3 PCI Express MiniSAS-HD / iPass+™ HD Host Adapter

The PXH830 Gen3 PCI Express NTB Host Adapter is our high performance clustering product. Based on Broadcom® Gen3 PCI Express bridging architecture, the PXH830 NTB host adapter includes advanced features for non-transparent bridging (NTB) and clock isolation. The PXH830 card will utilize the new MiniSAS-HD / iPass+™ HD connectors currently being standardized by the PCI-SIG as the new cable PCIe Gen3 cable option. The adapter card supports the full Dolphin eXpressWare software stack.

Product Data

The PXH830 Gen3 PCI Express NTB Host Adapter is our high performance cabled interface to external processor subsystems. Based on Avago® Gen3 PCI Express bridging architecture, the PXH830 host adapter includes advanced features for non-transparent bridging (NTB) and clock isolation. The PXH830 card will utilize the new MiniSAS-HD / iPass+™ HD connectors currently being standardized by the PCI-SIG as the new PCIe Gen3 cable option.

For high performance application developers, the PXH830 host adapter combines 128 Gbit/s performance with an application to application latency starting at 0.54 microseconds. Inter-processor communication benefits from the high throughput and low latency. Using the latest SmartIO technology software from Dolphin, applications can now access remote PCIe devices as if they was attached to the local system.

The PXH830 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 exceeding 11 Gigabytes pr second. 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.

The PXH830 is carefully designed for maximum cable length and supports copper cables up to 9 meters at full PCI Express Gen3 speed. Fiber optics extends this distance to 100 meters.

The PXH830 card comes with a full license to the Dolphin eXpressWare software. The PXH832 Gen3 Adapter card does not include any software license and is well suited for high performance Transparent IO Expansion applications.
