Devices, systems and methods for providing a daisy-chain topology for networking compute devices having PCIe bridges are disclosed. The daisy-chain topology is an extensible PCIe or similar standard solution that allows for a variable number of nodes. The topology has no chassis and no fixed slots, and there is no single device or bridge designated as the PCIe root. This topology allows additional devices to be added to the daisy-chain without construction of a new chassis. Some or all of can be mechanically coupled to provide a common communication channel. Once connected on the expansion link, any device has the ability to communicate to any other device on the daisy-chain. The devices on the daisy-chain are able to let their CPU or processors directly talk to those of another device. This results in a master/master relationship rather than one device serving as the master and the remaining devices the slaves.
