PXH82X Gen 3 XMC host / target and NTB adapter
The PXH82x product line includes two types of adapters, the PXH820/PXH824 NTB adapter for host-to-host communication and the PXH822/PXH826 for transparent host / target operation. The PXH820 and PXH822 support VITA 42.0 XMC 1.0, while the PXH824 and PXH826 support VITA 61.0 XMC 2.0.
The PXH820/24 Gen3 PCI Express NTB Host Adapter is our high-performance cable adapter to external processor systems. Based on the Broadcom® Gen3 PCI Express bridging architecture, the PXH820/24 host adapters include advanced features for non-transparent bridges (NTB) and clock isolation. The PXH820/24 cards use standard quad SFF-8644 connector and MiniSAS-HD cable.
For developers of high-performance applications, the PXH820/24 offers host adapters
data throughput of 128 Gbit / s combined with latency from 0.54 microseconds at the application level. Inter-processor communication benefits from high throughput and low latency.
Both adapters support remote DMA (RDMA) and programmed I / O (PIO) transfers for efficient transfer of large and small data packets. RDMA enables the high speed transfer of larger packets while off-loading the CPU and reaches more than 13 gigabytes per second date rates, whereas PIO transfers are optimal for small packet sizes and achieve the lowest latency. This combination of RDMA and PIO creates a powerful data transmission system.
Dolphins eXpressWare software uses both transmission modes to provide a complete application environment for customized and standardized applications. With Dolphin's latest SmartIO technology software, applications can now access remote PCIe devices as if they were connected to the local system.
PXH82X adapters are designed for maximum cable lengths and support copper cables up to 9 meters at full PCI Express Gen3 speed. Glass fiber optics extend this distance to 100 meters.
The PXH822/26 Gen3 PCIe Host/ Target XMC adapters are high-performance cable adapters for connecting external I / O subsystems using VPX and VME systems. Based on the Broadcom® Gen3 PCI Express bridging architecture, the PXH822/26 transparent host and target adapters contain advanced functions for transparent bridges (TB) and clock isolation. The PXH822/26 cards use a standard quad SFF-8644 connector that supports standard MiniSAS-HD cables or the new PCIe 3.0 cables.
The PXH822/26 designs reach maximum cable lengths with both copper cables, up to 9 meters at full PCI Express Gen3 speed, and fiber optic cables that extend this distance to 100 meters. The PXH822/26 cards are exclusively transparent products. To use Dolphins PCIe clustering software, a PXH820/24 must be purchased.
