Hi all,
I'd like to give a short update on the LightNVM Open-Channel SSD
integration [1,2]. The block layer plumbing and specification is coming
along and the first devices are becoming available.
The LightNVM integration allows SSDs to expose their internal
organization and control the flow of data towards flash. I believe this
can benefit both file systems, as well as user-space programs accessing
devices directly. I'd like to discuss how information is presented to
file-systems, how to direct write patterns, how user-space application
can optimize data access, etc.
Furthermore, it may also be interesting to discuss if and how other
interfaces can be integrated to make use of Open-channel SSDs.
