Enabling Bigger, More Affordable Memory Solutions

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.

Cost Efficiency and Overall Savings
Intel® Memory Drive Technology allows data centers to implement the same amount of memory for a significantly lower cost compared to all-DRAM installations, or alternatively, achieve much larger amounts of memory than the practical limitations of a given server DRAM-only capacity.

The chart on the right compares the cost per KVM* + Redis* Virtual Machine (VM) structure of:

  • A DRAM-only dual-processor server with 192GB of memory
  • The same dual-processor server configuration with 192GB DRAM complemented by Intel® Memory Drive Technology to expand overall system memory pool to 768GB total1
  • With otherwise identical server configurations, expanding the overall system memory footprint with additional Intel® Memory Drive Technology capacity decreases the cost per VM by greater than 50%1 when compared to the smaller all-DRAM set
