Abstract

The present disclosure describes apparatuses and methods for virtualizing isolation areas of solid-state storage media. In some aspects, a storage media accelerator determines, via a storage media interface, a geometry of solid-state storage media. The accelerator selects, based on the geometry, an area of the solid-state storage media as an isolated unit of storage. A physical address of the isolated unit of storage is then mapped to a virtual address. The accelerator exposes, via the virtual address, the isolated unit of storage through a host interface to enable host access of the isolated unit of storage. The accelerator may also remap the isolated unit of storage to other areas of the solid-state storage media without host interaction. By so doing, the accelerator may provide virtualized isolation and partitioning functionalities to a host, while efficiently handling lower-level storage media functions, such as wear leveling and load balancing, without host involvement.
