Apparatus, system, and method for atomic storage operations

A non-transitory computer-readable storage medium comprising machine-readable instructions configured to cause a machine to perform a method for servicing an atomic storage request, the method comprising:

• maintaining a forward index comprising bindings between logical identifiers in a logical address space of the non-volatile storage device and physical storage locations on the non-volatile storage device;
• storing data of an atomic storage request in a sequential log-based format in one or more storage operations on the non-volatile storage device, wherein data of the atomic storage request is stored on the non-volatile storage device together with persistent metadata indicating that the data pertains to an atomic storage request;
• maintaining an inflight index to associate logical identifiers of the atomic storage request with physical storage locations on the non-volatile storage device;
• and
• preserving the forward index while the one or more storage operations of the atomic storage request are performed.

An apparatus for providing atomic storage operations, comprising:

• a non-volatile storage device comprising a non-volatile storage media;
• and
• a virtual storage layer to:
• receive an atomic storage request from the storage client the atomic storage request comprising noncontiguous logical identifiers in a logical address space of the non-volatile storage device, and
• store data of the atomic storage request on the non-volatile storage device in a log-based format in one or more storage operations, wherein the data of the atomic storage request is stored together with persistent metadata that identifies the data as pertaining to an atomic storage request, and
• acknowledge completion of the atomic storage request to the storage client.
