INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING SYSTEM, CONNECTION CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING CONNECTION CONTROL PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18022387 titled 'INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING SYSTEM, CONNECTION CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING CONNECTION CONTROL PROGRAM

Simplified Explanation

The abstract of the patent application describes a host system that includes a PCIe Root Complex, a PCIe Expander connected to a general-purpose network, and a PCIe switch. The switch is responsible for switching the connection between the Root Complex and the Expander. When the host functions as a master, the Expander enables PCIe ports connected to upstream ports of the Root Complex and the Expander, while disabling a PCIe port connected to a downstream port of the Expander. When the host functions as a slave, the Expander disables the upstream port and the downstream port, and enables the upstream port.

  • The patent application describes a host system with a PCIe Root Complex, a PCIe Expander, and a PCIe switch.
  • The Expander enables and disables PCIe ports based on the host's function as a master or slave.
  • The switch is responsible for switching the connection between the Root Complex and the Expander.

Potential Applications:

  • This technology can be used in computer systems that require flexible switching between different PCIe devices.
  • It can be applied in data centers to optimize the connectivity and performance of PCIe devices.

Problems Solved:

  • The technology solves the problem of efficiently managing the connection and switching of PCIe devices in a host system.
  • It provides a solution for enabling and disabling specific PCIe ports based on the host's function.

Benefits:

  • The technology allows for flexible and efficient switching between PCIe devices.
  • It improves the performance and connectivity of PCIe devices in a host system.
  • The ability to enable and disable specific PCIe ports based on the host's function enhances system control and management.


Original Abstract Submitted

A host () includes a PCIe Root Complex (), a PCIe Expander () configured to be connected to a general-purpose network N, and a PCIe switch () including PCIe ports and configured to switch a connection between the Root Complex () and the Expander (), in which the Expander () enables PCIe ports () connected to upstream ports of the Root Complex () and the Expander () and disables a PCIe port () connected to a downstream port of the Expander () when the host () functions as a master, and disables the upstream port () and the downstream port () and enables the upstream port () when the host functions as a slave.
