A system includes a scalability port switch (SPS) and a plurality of nodes. The SPS has a plurality of ports, each port coupled to a node. Each port is connected to a scalability port protocol distributed (SPPD). A snoop filter in the SPS tracks which nodes may be using various memory addresses. A scalability port protocol central (SPPC) is responsible for processing messages to support coherent and non-coherent transactions in the system.
