+
+         Open-Channel SSDs implement a set of extension to SSDs, that
+         exposes direct access to the underlying non-volatile memory.

+       NVM media manager for Open-Channel SSDs that offload management

+       ---help---
+       Allows an open-channel SSD to be exposed as a block device to the
+       host. The target is implemented using a linear mapping table and
+       cost-based garbage collection. It is optimized for 4K IO sizes.
