Transparently Integrate SSDs into the Memory Subsystem

Intel® Memory Drive Technology is a revolutionary software that extends system memory transparently. Combined with an Intel® Optane™ Solid State Drive (SSD), Intel® Memory Drive Technology transparently integrates the SSD into the memory subsystem and makes it appear like DRAM to the OS and applications. Intel® Memory Drive Technology increases memory capacity beyond DRAM limitations in a completely transparent manner to the operating system and application. In addition, no changes are required to the OS or applications.

Enable New Possibilities

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.

Workloads that Benefit Most from Intel® Memory Drive Technology

Intel® Memory Drive Technology takes advantage of one or more of the following workload attributes:

  1. Predictable or probability-based memory access patterns, such as accesses to structured arrays - handled by prefetch algorithms. For example, row- or column-store in-memory databases used in analytics workloads.
  2. Highly concurrent memory access such as parallel throughput workloads - handled through asynchronous memory load. For example, container-based virtual-shared web-hosting server, or a multi-threaded key-value cache such as memcached.
  3. CPU intensive workloads - handled by optimizing the memory to CPU affinity throughout the run. For example, multi-threaded linear algebra workloads with large matrices, or parallel statistics calculations on large data.

System Memory at a Fraction of the DRAM Cost White Paper

1 GB = 1,073,741,824 bytes, TB = 1,099,511,627,776 bytes.
2 Total physical capacity is 375GB, 750GB, and 1500GB. Total usable capacity towards Intel® Memory Drive Technology is 320 GB. 640GB, 1280GB.
3 Technology licensed from ScaleMP*.
4 Software boots from USB media, network image (PXE boot) or directly from Intel® Optane™ SSD in UEFI mode.
5 For example: 128GB DRAM can be expanded up to 1024GB based on the capacity of the non-volatile memory media installed. Higher expansion ratios may be supported, with possibly suboptimal performance.
