The Express11-G3 PCI Express Gen 3 Expansion Backplane and Switch from Datapath provides eleven PCIe x16 (x8) slots, delivering 96 PCIe 3.0 lanes with up to 8 GB/s full duplex links. Using the PICMG 1.3 SBC host interface, this ATX backplane may be used as a standalone expansion or alongside multiple backplanes in a star or daisy-chain configuration.
The backplane also includes two SATA III and two USB 2.0 headers through the PICMG 1.3 interface. It also supports up to three fans.
Star Configuration
All x8 PCI Express slots in the master chassis (containing the SBC) are populated with a separately purchased HLink-G3 card. Each HLink-G3 is then connected to an expansion chassis using an ExCable-G3 and SLink-G3 card. This configuration provides a high number of available PCI Express slots supporting low latency.
Daisy-Chain Configuration
Daisy-chain the main chassis to a maximum of five expansion chassis providing up to 51 PCI Express expansion slots.
