The PXH83X product line support two types of adapters, the PXH830 NTB adapter for host to host communication and the PXH832 for transparent host/target operation.
The PXH830 Gen3 PCI Express NTB Host Adapter is our high performance cabled interface to external processor subsystems. Based on Broadcom® Gen3 PCI Express bridging architecture, the PXH830 host adapter includes advanced features for non-transparent bridging (NTB) and clock isolation. The PXH830 card have a standard Quad SFF-8644 connector and uses standard MiniSAS-HD cables.
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.
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 per 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 eXpressWare software takes advantage of PCI Express’ RDMA and PIO data transfer scheme. Delivering a complete deployment environment for customized and standardized applications. 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 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 PXH832 Gen3 PCI Express Host Adapter is our high performance cabled interface to external IO subsystems. Based on Broadcom® Gen3 PCI Express bridging architecture, the PXH832 Transparent Host and Target adapter includes advanced features for transparent bridging (TB), host and clock isolation. The PXH832 card utilizes a quad SFF-8644 connector and can use standard MiniSAS-HD or the new PCIe 3.0 cable currently being standardized by the PCI-SIG.
The PXH832 supports the new CMI functionality when used with a PCIe 3.0 cable and can therefore connect to a CMI compliant PCIe target device. The PXH832 can also be used with a standard MiniSAS-HD cable when connecting to a PXH832 in target mode. When used with a MiniSAS-HD cable, only the reset sideband signal will be emulated by the PXH832.
The PXH832 is carefully designed for maximum cable length and supports MiniSAS-HD copper cables up to 9 meters at full PCI Express Gen3 speed. Fiber optics extends this distance to 100 meters. The PXH832 card is a transparent only product. To utilize Dolphin's PCIe clustering software, you need to purchase the PXH830 adapter..
