Next, there's an update about the Optane roadmap. Here's a summary of what Intel had to say at its Architecture Day:
Memory and Storage: Intel discussed updates on Intel® Optane™ technology and the products based upon that technology. Intel® Optane™ DC persistent memory is a new product that converges memory-like performance with the data persistence and large capacity of storage. The revolutionary technology brings more data closer to the CPU for faster processing of bigger data sets like those used in AI and large databases. Its large capacity and data persistence reduces the need to make time-consuming trips to storage, which can improve workload performance. Intel Optane DC persistent memory delivers cache line (64B) reads to the CPU. On average, the average idle read latency with Optane persistent memory is expected to be about 350 nanoseconds when applications direct the read operation to Optane persistent memory, or when the requested data is not cached in DRAM. For scale, an Optane DC SSD has an average idle read latency of about 10,000 nanoseconds (10 microseconds), a remarkable improvement.2 In cases where requested data is in DRAM, either cached by the CPU's memory controller or directed by the application, memory sub-system responsiveness is expected to be identical to DRAM (<100 nanoseconds).
The company also showed how SSDs based on Intel's 1 Terabit QLC NAND die move more bulk data from HDDs to SSDs, allowing faster access to that data.
The combination of Intel Optane SSDs with QLC NAND SSDs will enable lower latency access to data used most frequently. Taken together, these platform and memory advances complete the memory and storage hierarchy providing the right set of choices for systems and applications.
