A system manages communication between a non-volatile memory express-over fabric (NVMe-oF) host unit and multiple non-volatile memory express-solid state drive (NVMe-SSD) storage devices via a bridge unit. The bridge unit may include sub-modules to control operations. The bridge unit may generate a virtual data memory address corresponding to a scattered gathered list address. The bridge unit may not require a data buffer to store intermediate data. The system may be configured to initiate a memory WRITE/READ transaction to access a virtual data memory corresponding to a physical memory in the bridge unit for performing a data WRITE/READ operation by an NVMe-SSD storage device.
