Accelerating Unmodified Databases using Persistent Memory and Flash Storage Tiers
Amit Golander, Netanel Katzburg, Omer Zilberberg · 2018
Recent breakthroughs in Storage Class Memory (SCM) technologies have driven Persistent Memory (PM) devices to become commodity off-the-shelf components in 2018. PM devices are byte addressable, plug into the memory interconnect, and run at near memory speeds, densities and price points. PM availability is led by Fast PM, comprised from backed-DRAM devices such as NVDIMM-N, and will follow soon with Slow PM, comprised of new SCM materials, such as Intel 3D XPoint NVDIMM. Fast and Slow PM devices vary in speeds, densities and cost, but both are orders of magnitude faster than Flash devices and an order of magnitude more expensive per GB.
