Abstract: Techniques are disclosed relating to enabling virtual machines to access data on a physical recording medium. In one embodiment, a computing system provides a logical address space for a storage device to an allocation agent that is executable to allocate the logical address space to a plurality of virtual machines having access to the storage device. In such an embodiment, the logical address space is larger than a physical address space of the storage device. The computing system may then process a storage request from one of the plurality of virtual machines. In some embodiments, the allocation agent is a hypervisor executing on the computing system. In some embodiments, the computing system tracks utilizations of the storage device by the plurality of virtual machines, and based on the utilizations, enforces a quality of service level associated with one or more of the plurality of virtual machines.

Abstract: A memory device includes a memory array with a plurality of memory elements. Each memory element is configured to store data. The device includes an input/output (I/O) buffer coupled to the memory array. The I/O buffer is configured to receive data from an I/O interface of a memory device controller and write the data to the memory array. The device includes a memory control manager coupled to the memory array. The memory control manager is configured to pause a program operation to the memory array in response to receiving a pause command. The memory control manager is also configured to resume the program operation in response to receiving a resume command.
