Enabling Bigger, More Affordable Memory Solutions

Intel® Optane™ SSD DC P4800X/P4801X and Intel® Optane™ SSD 900P/905P with Intel® Memory Drive Technology data center.

Intel® Memory Drive Technology transparently integrates Intel® Optane™ SSDs into the memory subsystem.

Intel® Memory Drive Technology can revolutionize your data center memory architecture. When combined with Intel® Optane™ SSDs, Intel® Memory Drive Technology transparently integrates the drive into the memory subsystem and makes it appear like DRAM to the operating system and applications. This can increase memory capacity beyond DRAM limitations, with no change required to the OS or applications.

Intel® Memory Drive Technology is highly beneficial in two primary IT scenarios:

  • Displace a portion of more expensive DRAM to reduce overall memory cost
  • Grow the memory pool beyond DRAM capacities to access or enable much larger memory datasets

Displace Costly DRAM for More Affordable Memory
Intel® Memory Drive Technology enables data centers to deliver more affordable memory pools by displacing a portion of higher cost, higher power DRAM. By pairing a reduced amount of DRAM and replacing that capacity with the high-performing non-volatile memory of the Intel® Optane™ SSD DC P4800X, data centers can more cost-effectively execute memory-intensive workloads with much lower DRAM capacity installed, saving on both hardware procurement and operations cost.

Extend Memory for a Bigger Memory Footprint
Intel® Memory Drive Technology enables data centers to grow the memory footprint beyond DRAM-only capacity. Together, DRAM and Intel® Optane™ SSDs with Intel® Memory Drive Technology emulate a single volatile memory pool. Additionally, Intel® Memory Drive Technology intelligently determines where data should be located within the pool to maximize speed, enabling servers to deliver performance across many workloads—even when DRAM is only supplying one-third to one-eighth of the memory pool capacity.

Enable New Possibilities for the Enterprise
The combination of cost-efficiency and increased capacity means enterprises can break through today’s memory limits, enabling new possibilities—like accessing higher-capacity, in-memory datasets to deliver better, faster analytics insight. As an example, cloud providers can reduce capital cost for memory when enabled to oversubscribe workloads with greater overall capacity. Or, high-performance computing centers can increase large memory datasets to improve research and scientific results, and test new simulations quickly and cost-efficiently.

Software and workloads used in performance tests may have been optimized for performance only on Intel® microprocessors.

Performance tests, such as SYSmark* and MobileMark*, are measured using specific computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products. For more complete information visit http://www.intel.com/benchmarks.

Performance results are based on testing as of July 5, 2018 and may not reflect all publicly available security updates. See configuration disclosure for details. No product can be absolutely secure.
