Intel Optane DC Persistent Memory
Intel Optane DC Persistent memory is the combination of Intel 3D Xpoint memory and the DDR4 memory bus bringing about a new type of memory for servers based on Intel’s 2nd Generation Xeon Scalable processor. As previously mentioned, 3D Xpoint has greater density, and lower cost per gigabyte compared to DRAM and is non-volatile making it possible to increase system memory using 3D Xpoint DIMMS sold under the Optane brand. This has significant benefits for overcoming bottlenecks in high end server applications particularly around big data where more memory can enable the analysis of larger pools of data.
Intel Optane DC Persistent memory will not 100% replace DRAM as the configuration requires a 4:1 ration of PIMM to DRAM but utilizing Optane DC Persistent memory does allow for up to 4.5TB of memory per CPU socket or up to 36TB of system level memory in an eight socket server. In addition to adding capacity, Intel Optane DC Persistent memory brings large pools of data into memory that is closer to the processor providing for much faster access to that data.
