Memory mapping for object-based storage devices

摘要

In an approach for determining a physical address for object access in an object-based storage device (OSD) system, a processor divides a first data object into one or more partitions, including at least a first partition, and providing each partition for storage as individual stored objects in an OSD system. A processor adds a first entry in a page table, the first entry representing the first partition without an indication of a physical address. A memory management unit (MMU) of the OSD system receives a first request of the first partition. Responsive to receiving the first request of the first partition, a MMU identifies that the first entry of the page table represents the first partition. A MMU obtains a physical address of the first partition from one of a hardware component and a firmware component.
