Intel® Optane™ Persistent Memory BIOS Optimization

Intel® Optane™ persistent memory 100 series (Intel® Optane™ PMem) coexists with traditional DDR4 DIMMs on the same bus. The memory controller in the 2nd Generation Intel® Xeon® Scalable processor arbitrates between the memory transactions coming from DRAM and Intel Optane PMem. Different arbitration profiles have been defined to determine the algorithm for when the memory controller switches between DRAM and Intel Optane PMem memory transactions. These profiles are configurable options through a persistent memory BIOS setting.
