How HPE Persistent Memory Furthers Our Vision of Memory-Driven Computing

When we first introduced the HPE Persistent Memory category at HPE Discover London 2015, we planted the first product flag in the market on our journey to Memory-Driven Computing.  Our vision of Memory-Driven Computing lets us put memory at the center of the computing platform to realize performance and efficiency gains not possible with today’s computer architecture. And while Memory-Driven Computing’s vision is much broader than Persistent Memory, the power of Persistent Memory is an important milestone in our journey to realize that vision!

Let’s start with some basics. HPE Persistent Memory solves the problems of time that is wasted whenever your application has to transfer data from the memory space to non-volatile storage. Effectively, HPE Persistent Memory becomes a new tier of storage inside an HPE ProLiant server, vastly quicker than the fastest Flash drive. Conventional DRAM server memory is “volatile”, meaning that data is lost when the power is lost. Because of that volatility, as your application data state changes in memory, you periodically have to save that data to non-volatile storage media like HDDs or SSDs. When your data leaves the low-latency memory space, this creates longer latency and thus introduces potential storage bottlenecks. What if your data never had to leave the memory space because that memory was not volatile? We achieved that non-volatility, or persistence – by augmenting the DRAM with Flash memory, right there on the same memory module. Keeping critical data in flash-backed memory eliminates the storage bottlenecks that happen when data leaves the memory space to be written to non-volatile media.

Our first product line in the HPE Persistent Memory product category, HPE NVDIMMs, are great with solving small storage bottlenecks – like database transaction logs, index files and write caching tiers where you write to the low-latency DRAM on the NVDIMM. But how do you bring the performance levels of persistent memory to larger scale workloads like databases and analytics? We recently introduced HPE Scalable Persistent Memory which delivers terabyte-scale persistent memory and enables you to do much larger in-memory compute backed by flash.Slide1.JPG

With HPE Scalable Persistent Memory, we recently achieved the #1 TPC-H benchmark on the 2-socket HPE ProLiant DL380 Gen10 server running a 1TB Microsoft SQL Server 2017 “Diskless Database”, achieving over 1 million queries per hour (QphH) and beating the previous record holder performance by 45%. The good people that referee this benchmark told us they’d never seen the record broken by such a large margin! We also delivered 3x faster SQL Server 2017 analytics using Microsoft Storage Spaces Direct compared to using NVMe SSDs alone. HPE is clearly delivering unprecedented levels of performance with HPE Persistent Memory technology.

So how does HPE Persistent Memory help deliver on the vision of Memory-Driven Computing? Well – you don’t realize your vision without steps along the journey to help you arrive to your vision. And one of those important steps is what I call software ecosystem enablement – which is getting operating system and software applications ready to tap into the performance and efficiency potential of Memory-Driven Computing. The HPE Persistent Memory team has continually been working with operating system and application providers to bring real world innovation to the market. The #1 TPC-H benchmark and 3x faster SQL Server 2017 analytics are just two of many examples of that innovation. Another great example of getting the software ecosystem ready for Persistent Memory and Memory-Driven Computing is our partnership with VMware. In this video, VMware talks about how HPE and VMware are working together to bring the benefits of Memory-Driven Computing to the virtualized datacenter.

Memory-Driven Computing holds great promise in solving the complex problems of future – from space exploration to data-driven cures for disease to running the homes and cities of tomorrow. HPE Persistent Memory is your on-ramp to Memory-Driven Computing and the future! To learn more, please visit our website and stay tuned for more exciting announcements in the future!

You can elaborate more with NVDIMM N,P,F and how the byte addressability block addressability....... help..

cool stuff, but unfortunately now no longer available (was sold only for a few month):

876401-B21  HPE Scalable PMEM 256GB    -> obsolete

876402-B21  HPE Scalable PMEM 512GB      -> obsolete

827608-B21  HPE Scalable PMEM 800W PSU/400W BBU -> obsolete

 will there be a replacement?
