  7. About Data Hotness in Hybrid Storage Systems

    Intro With the development of storage device, lots of novel stuff come to world, including NAND SSD, Optane 3D XPoint, STT-RAM… Personal machines have already multi-level storage: SRAM on CPU L2/L2 cache, DRAM on CPU’s DIMMs, SSD to accelerate operating system, and HDD to storage big file like media, movie.
