Intel® Optane DC Persistent Memory

What is DCPMM?

• DCPMM stands for Intel® OptaneTM DC Persistent Memory Module.
• There is a performance gap between DDR4 memory and NVMe SSDs
• Traditional DDR4 has capacity limitations, while NVMe SSDs have latency limitations.
• DPMM takes the storage capacity of an SSD, and puts it into a DDR4 form factor.

Why DCPMM?

Flexibility

• DCPMM can be configured as storage, and it has better performance than NVMe SSDs.
• DCPMM can be configured as memory, and it has greater or equal capacity compared to DDR4 memory.

Cost Effective

• It can have the better price-to-capacity ratio compared to traditional DDR4 memory.

Security

• DCPMM has built-in hardware encryption to keep your data secure.
