A memory sub-system connectable to a microprocessor to provide network storage services. The memory sub-system has a random-access memory configured with: first queues for the microprocessor and a network interface; second queues for the microprocessor and a processing device; and third queues for the processing device and a storage device. The processing device is configured to: generate first control messages and first data messages from packets received by the network interface; place the first control messages into the first queues for the microprocessor; and place the first data messages into the third queues for the storage device. The microprocessor processes the first control messages to implement security and administrative functions and place second control messages in the second queues. The storage device is configured to retrieve the first data messages from the third queues and second control messages from the second queues for processing.
