The GX1 offers a cost-effective PCIe Gen 3 switching solution via the CompactPCI Serial backplane. It comes with Express Switch or Express Fabric functionality. Some typical industrial applications include multi-CPU high speed video and image processing, supercomputing and virtualization. The GX1’s final configuration depends on the end application. It is only available within a project context and cannot be ordered as a single standard product.

High-Speed Connection

The GX1 enables high speed serial point-to-point communication between the CPUs and between the CPUs and end point modules. Configurable data transfer rates can reach up to 985 MB/s per PCIe lane.

Flexible Configuration of Multi-Processor Systems

The switch allows connection of multiple endpoints and multiple CPUs. This way, it is possible to build powerful and cost-effective multi-processor systems. The switch ports can be configured flexibly using an application running on the root complex CPU. This way, the switch can be adapted to different backplane designs. No programming is required to set up the ports. Setup and diagnostics tools are available from the chip manufacturer.

Express Switch Functionality

The GX1 supports both multi-root and multi-host configuration. For multi-root configuration, the GX1 can be partitioned into four fixed virtual bridges supporting up to four root complexes. Each root complex is allowed to enumerate its own endpoints. Non-transparent bridging is not required in this case. For multi-host configuration, the primary host CPU is acting as a root complex enumerating all the endpoints and up to two additional secondary host CPUs connected over two non-transparent bridges. In this configuration, all host CPUs are able to communicate with all endpoints. Using the non-transparent bridging the primary CPU is able to share control, status and interrupt information with the secondary hosts. This allows more efficient load sharing in data intensive computing applications.

Express Fabric Functionality

GX1 can also be equipped with an Express Fabric chip which is especially suitable for complex non-hierarchical PCI Express topologies such as Mesh and Fat Tree. It supports single-root I/O virtualization which means that I/O can be shared among multiple hosts similar to the way Virtual Machines (VMs) share a piece of hardware on the same host. Express Fabric makes it possible to use more than 3 CPU boards in one configuration.

The GP1 is a 3U Gigabit Ethernet PHY line card, with optional PoE support, implemented as a CompactPCI Serial board. It occupies one peripheral slot using a 4 HP front panel with four Gigabit Ethernet ports on RJ45 connectors. Alternatively, the GP1 can be supplied with four M12 A-coded connectors on the front panel (X-coded variants in preparation).

The GP1 is designed to work in combination with the G101 CompactPCI Serial managed industrial Ethernet switch.

The GP1 features four connectors on the front panel, which can be used to create 4 ports of copper Gigabit Ethernet. In addition, the card can act as Power over Ethernet (PoE) Power Sourcing Equipment (PSE), supplying other devices on all ports with power. Each interface supports a data transfer rate of 1 Gbit/s, and provides two LEDs to indicate the link and activity status.

The GP1 operates with a primary voltage supply of +12 V, which is provided via the rear CompactPCI serial connector. All additional required voltages are generated onboard. It is fully compliant with the EN 50155 railway standard, qualified for a -40 to +85°C operation temperature and ready for coating.
