摘要:
Embodiments of the present invention provide a flash memory device write-access management amongst different virtual machines (VMs) in a virtualized computing environment. In one embodiment, a virtualized computing data processing system can include a host computer with at least one processor and memory and different VMs executing in the host computer. The system also can include a flash memory device coupled to the host computer and accessible by the VMs. Finally, a flash memory controller can manage access to the flash memory device. The controller can include program code enabled to compute a contemporaneous bandwidth of requests for write operations for the flash memory device, to allocate a corresponding number of tokens to the VMs, to accept write requests to the flash memory device from the VMs only when accompanied by a token and to repeat the computing, allocating and accepting after a lapse of a pre-determined time period.
