Abstract: A system and method including a PCIe slot, a storage device coupled to the PCIe slot, and a host server including a processor and a non-transitory memory including machine-readable instructions that, when executed by a processor, cause the processor to: load a RAID driver; receive, by the RAID driver, a probe call identifying the PCIe slot; determine, based on a slot reservation table stored in a non-volatile RAM accessible by the RAID driver, whether the storage device coupled to the PCIe slot is managed by the RAID driver; send, when the PCIe slot is identified in the slot reservation table, a response indicating that the RAID driver will control access to the storage device coupled to the PCIe slot; and send, when the PCIe slot is not identified in the slot reservation table, a response indicating that the RAID driver will not control access to the storage device.

Abstract: System and method for sharing a PCIe endpoint device with a plurality of host computers, by allocating a quantum of time to a host computer of a plurality of host computers coupled to a PCIe switch, wherein the quantum of time identifies a duration of time during which the host computer has exclusive access to a shareable PCIe endpoint device coupled to the PCIe switch. Requests from the host computer are transmitted to an emulated PCIe endpoint device of the PCIe switch during the quantum of time and the requests are then redirected from the emulated PCIe endpoint device to the shareable PCIe endpoint device during the quantum of time allocated to the host computer.
