Abstract: Systems, methods, and a bridge device for a data storage device array that enables data transfer between data storage devices without transferring data to the host system are described. The bridge device receives a data transfer command from the host system, such as a fused read and write command, and converts it to separate read and write commands for the source and destination storage devices. The bridge device may operate in a non-volatile memory express over fabric (NVMe-oF) environment and manage the command queues, connection verifications, and command conversions to enable data transfer among storage devices connected to a shared peripheral component interface express (PCIe) root complex without using host network bandwidth or memory.
