  • Patent number: 6122756
    Abstract: A high availability computer system and methodology including a backplane, having at least one backplane communication bus and a diagnostic bus, a plurality of motherboards, each interfacing to the diagnostic bus. Each motherboard also includes a memory system including main memory distributed among the plurality of motherboards and a memory controller module for accessing said main memory interfacing to said motherboard communication bus. Each motherboard also includes at least one daughterboard, detachably connected to thereto. The motherboard further includes a backplane diagnostic bus interface mechanism interfacing each of the motherboards to the backplane diagnostic bus; a microcontroller for processing information and providing outputs and a test bus controller mechanism including registers therein.

  • Patent number: 6026461
    Abstract: A very fast, memory efficient, highly expandable, highly efficient CCNUMA processing system based on a hardware architecture that minimizes system bus contention, maximizes processing forward progress by maintaining strong ordering and avoiding retries, and implements a full-map directory structure cache coherency protocol. A Cache Coherent Non-Uniform Memory Access (CCNUMA) architecture is implemented in a system comprising a plurality of integrated modules each consisting of a motherboard and two daughterboards. The daughterboards, which plug into the motherboard, each contain two Job Processors (JPs), cache memory, and input/output (I/O) capabilities. Located directly on the motherboard are additional integrated I/O capabilities in the form of two Small Computer System Interfaces (SCSI) and one Local Area Network (LAN) interface. The motherboard includes main memory, a memory controller (MC) and directory DRAMs for cache coherency.
