摘要： An apparatus, system, and method are disclosed for implementing nameless storage operations. Storage clients can access and allocate portions of an address space of a non-volatile storage device to a nameless storage request. The methods include receiving from a storage client, a nameless storage request configured for storing data in an unspecified, available address of a logical block address of a non-volatile storage device, determining whether there exists enough logical capacity in the logical address space to satisfy the nameless storage request, allocating a logical identifier to the nameless storage request, and sending the allocated logical identifier to the storage client. Other embodiments are described.

摘要： An apparatus, system, and method are disclosed for implementing conditional storage operations. Storage clients access and allocate portions of an address space of a non-volatile storage device. A conditional storage request is provided, which causes data to be stored to the non-volatile storage device on the condition that the address space of the device can satisfy the entire request. If only a portion of the request can be satisfied, the conditional storage request may be deferred or fail. An atomic storage request is provided, which may comprise one or more storage operations. The atomic storage request succeeds if all of the one or more storage operations are complete successfully. If one or more of the storage operations fails, the atomic storage request is invalidated, which may comprise deallocating logical identifiers of the request and/or invalidating data on the non-volatile storage device pertaining to the request.

摘要： An apparatus includes an input/output (I/O) interface configured to couple a controller to an I/O buffer of a memory device. The controller includes an erase module coupled to the I/O interface. The erase module is configured to issue an instruction to the memory device to erase data from the memory device. The controller includes an erase suspend module coupled to the I/O interface. The erase suspend module is configured to determine that an erase operation executing within the electronic memory device satisfies a suspend policy in response to receiving a memory access request to perform an operation on the memory device on which the erase operation is executing. The erase suspend module is further configured to issue a suspend command to the memory device to suspend the erase operation.

摘要： 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.
