  • Queue depth management for host systems accessing a peripheral component interconnect express (PCIe) device via a PCIe switch
    Patent number: 10877913
    Abstract: Enhancements for managing quality of service in a multi-host Peripheral Component Interconnect Express (PCIe) switching environment involve a host system configured to maintain quality of service statistics corresponding to data interactions with a PCIe storage device available via a PCIe switch. The host system may further receive secondary quality of service statistics for one or more other host systems communicatively coupled to the PCIe device via the PCIe switch, and determine a maximum queue depth for the host system based on the quality of service statistics and the second quality of service statistics to maintain a quality of service for at least the host system.
    Type: Grant

    Date of Patent: December 29, 2020
    Assignee: Western Digital Technologies, Inc.

  • Queue depth management for host systems accessing a peripheral component interconnect express (PCIe) device via a PCIe switch
    Patent number: 10579567
    Abstract: Described herein are enhancements for managing quality of service in a multi-host Peripheral Component Interconnect Express (PCIe) switching environment. In one implementation, a host system is configured to maintain quality of service statistics corresponding to data interactions with a PCIe storage device available via a PCIe switch. The host system may further receive secondary quality of service statistics for one or more other host systems communicatively coupled to the PCIe device via the PCIe switch, and determine a maximum queue depth for the host system based on the quality of service statistics and the second quality of service statistics to maintain a quality of service for the host systems.
