I can understand how the Optane DC Persistent Memory is amazing by seeing the following movie in one shot.

Intel Optane DC Persistent Memory Fills Gap between DRAM and SSDs - YouTube


In the "data era" where the Internet spreads and IoT is about to reach full-scale dissemination, there are large distances between "memory high-speed but expensive DRAM" and "memory that can be increased inexpensively but slowed". did.


In order to fill this gap, "Memory with high capacity, high speed, low price" three times began memory, "Intel Optane" memory that has been developed as 3D Xpoint.


"Optane DC Persistent Memory" adopting the DIMM type module will appear in that Optane memory.


It is like this when memory is arranged from the left in the order of performance. Optane DC Persistent Memory is a high-speed, nonvolatile memory that fills the gap between DRAM and PCI-Express connection SSD.


It is the Optane DC Persistent Memory that acts as an intermediary to hold data from DRAM and pass it to SSD at an appropriate timing.


The major feature of Optane DC Persistent Memory is DIMM type. Optane memory can now be installed in the DDR4 memory slot, which is currently the most popular memory.


By introducing Optane DC Persistent Memory, reliability of data retention and ...


Advanced flexibility (recoverability)


It is possible to enhance confidentiality etc. by strong encryption.


By combining Optane DC Persistent Memory with Intel Xeon Scalable Processor, server performance can be further enhanced.


Data center performance required in data era where data is utilized everywhere is realized.


As explained in the movie, the Optane memory is a memory that fills the gap between DRAM and SSD, has high speed, large capacity, low price, and has nonvolatility. Optane memory of the PCI - Experss interface has already been released, but it was "Optane DC Persistent Memory" that appeared as a DIMM module - type Optane memory at a higher speed.


Optane DC Persistent Memory has a large capacity of 128 GB, 256 GB, 512 GB per one, and it is also possible to secure a large capacity of 3 TB or more per CPU socket. About Optane DC Persistent Memory Intel will begin shipping for some customers within 2018 and will be officially released in 2019.
