Leveraging Persistent Memory to Deliver Industry-Leading Performance


HPE Scalable Persistent Memory: industry-leading performance that transforms data into actionable information and enables your employees to interact with each other, customers, and business partners on a whole new level.

Blog_PersistentMemory_6_6.jpgBusinesses of all sizes are experiencing Digital Transformation. Whether it’s leveraging new sources of converged Big Data analytics, mobilizing workforces, leveraging cloud solutions, or plugging into the Internet of Things—digital technologies are revolutionizing the way business users interact with each other, customers, and business partners.

IT departments are responding through the deployment of new technologies that combine on-premise IT infrastructures with private and public cloud infrastructures. Hybrid IT environments are the new reality, and this fundamental change in how businesses get things done calls for new ways to accelerate business outcomes, protect the business, and consume IT.

Businesses essentially need to increase their IT agility in order to reduce deployment times and quickly provide new services. That means today’s compute and storage solutions must dramatically reduce their latency and improve throughput for metadata-heavy workflows and analytics while also accelerating database transaction speeds.

The speed of memory combined with the persistence of storage

A key technology helping to make this change possible is non-volatile persistent memory, which converges the speed of memory with the persistence of storage. Persistent memory efficiently stores data so that data structures can continue to be accessed by using memory instructions and memory APIs—even after the end of the process that created or last modified the data.

Although flash solid-state drives (SSDs) have revolutionized storage in the last decade, non-volatile persistent memory is a much bigger deal. Flash SSDs replaced rotating disks with much faster devices, but the entire I/O stack is the same and therefore all the issues of writing data to a device remain (i.e. latency, errors, and coordinating multiple buffers).

While SSDs are a faster disk, persistent memory is faster AND enables storage-class memory that can be used as storage. This bridges the gap between DRAM and storage drives; instead of a memory layer and a storage layer, servers can tap into a single layer of persistent memory.

Taking memory-driven computing to the next level

To capitalize on the benefits of persistent memory, many businesses are turning to HPE Scalable Persistent Memory. The solution integrates memory speeds with terabyte storage capacity to unlock new levels of performance for business workload optimization. For databases of all sizes, businesses can remove processing bottlenecks and gain several other key capabilities:

  • Real-time hybrid transactional and analytical processing
  • Speedier checkpoints and restores
  • Accelerated software-defined storage caching
  • Write caching

By leveraging non-volatile dual in-line memory, HPE Scalable Persistent Memory also delivers superior performance compared to solid-state discs:

  • 34x more IOs per second
  • 16x more bandwidth throughput
  • 81x lower latency

With this solution, HPE has taken memory-driven computing to the next level. Businesses can now process more data than has ever been achieved by a single memory system—enough power to process the data in every book of the U.S. Library of Congress five times over.

Persistent memory computing is primed to move every industry forward in the ways businesses transform data into actionable information, allowing them to interact with customers on a whole new level. The data center architecture we have developed for HPE Scalable Persistent Memory can be applied to every computing category, from intelligent edge devices to supercomputers.

Hi Michael, this is very interesting especially among our customers who work with large/big data sets. The post mentions TB storage capacity but the linked YouTube video showcases an 8GB NVDIMM. I'm curious, would you mind describing where HPE Scalable Persistant Memory fits in comparison to M.2 SSDs & the PCIe based NVMe cards (i.e. Intel's P3700 - 2TB).  Scalable Persistant Memory is lower capacity, but lower latency i'm guessing?
