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.

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.
