Scale out PCI Express with the IXS600

Product Data

The PXH812 is carefully designed to maximize cable length. With the implementation of clock isolation, internal clock generation, and a well designed PCB, the PXH812’s signal quality is excellent. By isolating the system clock and transmitting an extremely low jitter high quality clock to downstream devices, the PXH812 offers users high signal quality and increased cable distances. The PXH812 support copper cables up to 5 meters at full PCI Express Gen3 speed when connected to another PXH812 card. (*5 meter is currently qualified for room temperatures, higher operating temperatures are being tested.) Fiber optics is supported up to 100 meters at full speed.

The PXH812 is ideal in applications such as test and measurement equipment, medical equipment, and storage subsystem seeking high performance and data quality.

The PXH812 card support both Host upstream and Target downstream operations. This is easily selected by DIP switches before installation.

The PXH812 can be connected to the IXS600 Switch to create PCIe Gen3 scale out solutions. Combined with a single IXS600 switch, you can connect up to 7 cabled downstream devices or expansion chassis to a single host system.

The PXH812 card is a transparent only product. To utilize Dolphin's PCIe clustering software, you need to purchase the PXH810 Gen3 Adapter card.
