  • Multiprocessor system with independent direct access to bulk solid state memory resources
    Patent number: 11340794
    Abstract: A system has a collection of central processing units. Each central processing unit is connected to at least one other central processing unit and has a path into flash memory resources. A central processing unit supports a mapping from a data address space, to a flash memory virtual address space, to a flash memory virtual page number to a flash memory physical address space.
    Type: Grant
    Filed: December 17, 2018
    Date of Patent: May 24, 2022
    Assignee: EMC IP HOLDING COMPANY LLC

  • Multiprocessor system with independent direct access to bulk solid state memory resources
    Patent number: 10410693
    Abstract: A system includes a plurality of processors, each being coupled to each of remaining processors via a cluster of processor interconnects. The cluster of processor interconnects form a data distribution network. The system further includes a plurality of roots coupled to the processors, each root corresponding to one of the processors. Each root comprises a memory controller, one or more branches coupled to the memory controller, and a plurality of memory leaves coupled to the branches, each memory leaf having one or more solid state memory devices. Each of the branches is associated with one or more of the memory leaves and provides access to the associated memory leaves. Each of the processors can access any one of the memory leaves via a corresponding branch of any one of the roots over the data distribution network.

  • Multiprocessor system with independent direct access to bulk solid state memory resources
    Patent number: 9519615
    Abstract: A system includes a collection of central processing units, where each central processing unit is connected to at least one other central processing unit and a root path into at least 10 Tera Bytes of solid state memory resources. Each central processing unit directly accesses solid state memory resources without swapping solid state memory contents into main memory.
