Persistent memory is also capable of significantly increased memory capacity to up to 512 Gbytes, while providing increased performance and efficiency. This performance makes persistent memory ideal for applications such as in-memory databases, analytics, and content delivery networks.
Intel Optane persistent memory modules were developed to provide access to large, affordable memory capacity that is able to act as either volatile memory or a persistent, high-performance data tier. The persistent memory modules are DDR4 socket compatible and operate on the same bus/channels as DDR4 DRAM to simplify integration and provide design flexibility if conventional DDR4 DRAM DIMMs are being used on the same platform. The memory is able to operate as volatile memory capacity that is indistinguishable from DRAM from the software’s perspective. It can also act as non-volatile memory to retain data, such as in an SSD, but with 225 times faster data access than a typical NAND-based drive.
The Intel Optane persistent memory modules come in capacities of 128 GBbyte, 256 GByte, and 512 Gbyte. They are compatible with Intel’s 2nd Generation Xeon Scalable processor family, and allow the development of up to eight-socket systems supported by up to 24 TBytes of system memory. The modules provide higher system performance and larger memory that features higher endurance than NAND SSDs in write-intensive workloads.
Intel Optane persistent memory has two operating modes — App Direct Mode and Memory Mode, which allows developers to design their persistent memory solutions for specific workloads. The memories have been developed to operate at a place between memory and storage and support the development of new data-intensive applications while maximising processor performance.
