That is a good idea. There is a couple of papers at FAST with Open-Channel SSDs this year. They look into the interface and various ways to reduce latency fluctuations. One thing I've heard a couple of times is the feature to move the GC read/write process into the firmware. Enabling the host to offload GC data movement, while the keeping the host in control. Would this be beneficial for SMR? -Matias -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
