The Datapath Express11-G3 backplane provides 11 x8 lane PCI Express slots, all implemented as x16 physical connectors. They can be used with a standard PICMG 1.3 SBC as a standalone system or in combination with multiple backplanes to provide a PCI Express expansion system for a standard PC. This backplane uses advanced PCI Express 3.0 switches to create high bandwidth that connects up to 11 PCI express plug in cards into a host system. The Datapath Express11-G3 uses PCIe Gen.3 switches to provide each slot with up to 8GB/s bi-directional bandwidth. Using multiple Express11-G3 backplanes configured in a daisy chain expansion mode allows construction of large systems. The Express11-G3 can also be expanded using a star configuration. This configuration enables the construction of very large systems supporting low latency with a high number of slots.
