“…In effect this pulls the conventional device-level translation into the host, resulting in no fundamental change in the total (host plus device) DRAM usage and write amplification. 3 Systems that write large segments can use ZNS with little intervention [13]. (A light translation might be needed to map a segment to zones.)…”

“…Several projects have enabled byte-granular access to flash SSDs by leveraging their internal NVRAM. For instance, 2B-SSD enables the host to load a region of flash into the device NVRAM and access it using MMIO [3]. FlatFlash goes further by automating the transfer of data between flash and device NVRAM and between device NVRAM and host DRAM [1].…”

“…FastMap and Aquila provide specific optimizations only for the memory level and results in significant improvements in a file system and device agnostic manner. 2B-SSD[8] leverages SSD internal DRAM and the byte addressability of the PCIe interconnect to provide a dual, byte and block-addressable SSD device. It provides optimized write-ahead logging (WAL) over 2B-SSD for popular databases and results in significant improvements.…”
