Abstract
An interface receives storage requests for storing data in a software-defined storage network using an append-only storage scheme. The requests include an identifier of a data object to be stored. The requests are agnostic of hardware-specific details of the storage devices. A virtualization layer accesses space allocation data for the storage devices; and policies for prioritizing performance. Based on the data and policies, a physical storage location at the plurality of storage devices is selected for storing the data object. Metadata is generated for the data object indicating that the data object is an append-only object and mapping the physical storage location of the data object to the identifier. The request is translated to instructions for storing the data object at the physical storage location using the append-only storage scheme. The data object is stored at the physical storage location using the append-only storage scheme.
