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.
