A scalable computer node includes a first central processing unit (CPU), a memory subsystem, and a socket that is configured to receive a second CPU. An expansion module is mounted in the socket instead of the second CPU, where the expansion module is socket-compatible with the second CPU. The expansion module has a CPU interface to communicate with the first CPU, a memory interface to communicate with the memory subsystem, and a fabric interface to communicate over a communications fabric with an expansion electronic subsystem to expand a capacity of the computer node.
