The switch allows connection of multiple endpoints and multiple CPUs. Configurable data transfer rates can reach up to 985 MB/s per PCIe lane.įlexible Configuration of Multi-Processor Systems The GX1 enables high speed serial point-to-point communication between the CPUs and between the CPUs and end point modules. It is only available within a project context and cannot be ordered as a single standard product. The GX1's final configuration depends on the end application. Some typical industrial applications include multi-CPU high speed video and image processing, supercomputing and virtualization.
It comes with Express Switch or Express Fabric functionality. HBAs bridge to back-end SCSI domains Each back-end SCSI domain target port is addressable as a target port.The GX1 offers a cost-effective PCIe Gen 3 switching solution via the CompactPCI Serial backplane.
