Abstract:
1. A scalable computer node comprising: a first central processing unit (CPU); a memory subsystem; a socket that is configured to mount a second CPU that is different from a circuit board assembly having a circuit board; and a first expansion module mounted in the socket instead of the second CPU, wherein the first expansion module is socket-compatible with the second CPU, and wherein the first 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 that includes at least another CPU to expand a capacity of the computer node and that includes a second socket to mount a second expansion module having a CPU interface to communicate with the another CPU, and a fabric interface to communicate over a second communications fabric with another expansion electronic subsystem to modify the capacity of the computer node.
