PXH832 Host and Target Transparent Cable Adapter

Gen3 PCI Express Transparent Host and Target Adapter

The PXH832 Gen3 PCI Express Transparent Host and Target Cable Adapter is our high performance interface to external IO subsystems. Based on Broadcom® Gen3 PCI Express bridging architecture, the PXH832 adapter includes advanced features for transparent operations and clock isolation. The PXH832 card have a quad SFF-8644 connector and can utilize standard MiniSAS-HD cables or the new external PCI Express 3.0 cables currently being standardized by the PCI-SIG as the new cable PCIe Gen3 cable option.

Product Data

The PXH832 Gen3 PCI Express Host Adapter is our high performance cabled interface to external IO subsystems. Based on Avago® 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. More information on cables for the PXH832.

The PXH832 card is a transparent only product. To utilize Dolphin's PCIe clustering software, you need to purchase the PXH830 Gen3 NTB Adapter card.
