The PXH832 Gen3 Host/Target Adapter is our high performance cabled interface from host to I/O subsystems. Based on Broadcom® Gen3 PCI Express bridging architecture, the PXH832 adapter enables transparent PCIe connections and clock isolation. The PXH832 card utilizes 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 PXH832 adapter provide 128 Gb/s performance with the low latency of PCI Express. The PXH832 Transparent Host and Target adapter is ideal for I/O Expansion systems. The PXH832 can be configured as four x4 PCIe connections, two x8 or one x16 PCIe connection. For GPU farms, test and measurement equipment, medical equipment, and storage subsystem, the PXH832 delivers flexibility and 128 Gb/s with extremely high data quality. The adapter is configurable as both a host adapter or target adapter.
The PXH830 is carefully designed for maximum cable length and supports MiniSAS-HD copper cables up to 9 meters at full PCI Express Gen3 speed. Fiber optic cables extend this distance to 100 meters.
The PXH832 supports two types of copper cables. With the PXH832 as both Host and Target, standard MiniSAS-HD cables support basic transparent Host and Target operations including propagation of Host reset signal to the downstream device. When the PXH832 is used in conjunction with the new PCI-SIG external PCIe cables, any target can be used for basic transparent operation. The card also supports the new (Cable Management Interface ) CMI protocol including WAKE and POWER-ON functionality.
The PXH832 uses an on-board DIP-Switch to select between Host and Target operations.
