5. HPE Scalable Persistent Memory Use Cases
Storage at the speed of memory
Large in-memory compute with data persistence
Real Time Analytics
Faster Checkpoints and Restores
OLTP OLAP = HTAP
Use Cases for HPE Scalable Persistent Memory:
TB-scale in-memory compute with persistence. Utilizes DRAM for application performance with an added level of persistence with a flash backup tier.
Reducing database storage bottlenecks. Database performance can be vastly improved using low-latency DRAM to reduce or eliminate storage bottlenecks in lieu of using higher-latency block storage devices.
Many databases have separate operations for the transactional portion of the database and the analytics portions which uses data tables from the transactional portion. Customers can utilize TB-scale HPE Scalable Persistent Memory to enable real time analytics – known as HTAP – where they do the transactions and analytics simultaneously.
Software-defined storage implementations can also benefit from HPE Scalable Persistent Memory. From commercial applications such as FlashSoft or AutoCache to HPE StoreVirtual VSA and Microsoft Storage Spaces, HPE Scalable Persistent Memory can be used to eliminate storage bottlenecks in those implementations as well as be used as a fast caching tier.
The concept of checkpointing is when an application is running in-memory and data in-flight needs to be periodically checkpointed to non-volatile media like HDDs or SSDs. This operation typically is a bottleneck for an application and can impact application performance. What if you did that checkpoint to HPE Scalable Persistent Memory – using DRAM on the nanosecond latency memory bus? This can dramatically improve overall application performance. We have tested this in HPE internal labs and have seen up to a 27x performance improvement.
Restores using HPE Scalable Persistent Memory can also be a source of latency as you restore from HDDs or SSDs. When you restore from HPE Scalable Persistent Memory, you are restoring from DRAM with nanoseconds of latency on the memory bus. We have a documented use case where we restored a Microsoft SQL Server Hekaton in-memory database (200GB, running 500K Transactions Per Second (TPS)) using SSDs. That restore finished in a very respectable 20 mins. We then restored using HPE Scalable Persistent Memory and the restore went from 20 mins to 45 seconds! That’s an over 20x reduction in restore time!
Anywhere you have storage bottlenecks today, where you are writing to block storage devices and using a layer of persistent memory in place you can see huge benefits.
These are just a few of the many use cases for HPE Scalable Persistent Memory. Check often for the latest technical papers on emerging use cases.

6. Reducing Database Storage Bottlenecks Software Licensing Reduction
HPE NVDIMM Use Cases
Storage at the speed of memory
Reducing Database Storage Bottlenecks
Software Licensing Reduction
Write Caching
Up to 4x faster and better CPU Utilization with byte addressable storage.
Up to 50% reduction in core-based software licensing with NVDIMMs
Up to 2x faster with NVDIMMs than with NVMe SSDs
Key Messages:
HPE 8GB NVDIMMs support up to 16 NVDIMMs in a DL360 or DL380 Gen9 server featuring E5-2600v4 processors (Broadwell) for a total of 128GB of total capacity.
NVDIMMs are ideal for eliminating small storage bottlenecks and are the fastest tier of storage on HPE ProLiant servers.
Database Storage Bottlenecks – like transaction logs – are one of the biggest offenders of latency. That’s because the software is often waiting on the hardware to complete write operations. In SQL Server 2016, Microsoft changed the portion of the transaction log with the most recent writes – the Tail of the Log – to address HPE NVDIMMs as byte addressable storage. Now the transactions written to the log hit the DRAM on the NVDIMM greatly reducing the latency experience during transaction writes. This allows up to 4x faster performance and better CPU utilization (achieved through more efficient software operations from byte addressable software). 4x number compares writing transaction logs on SAS SSDs vs. NVDIMMs with SQL Server 2016 Tail of the Log byte addressable storage capability enabled.
Software licensing reduction. We compared an HPE ProLiant server running with 32 cores and SAS HDDs compared to an HPE ProLiant server running with 16 cores and NVDIMMs. The 16 cores with NVDIMMs outperformed the 32 core system with SAS HDDs – resulting in a 50% reduction in server cores. Many software apps like Oracle DB license software by the server core pair. This can result in substantial savings on software licensing costs.
NVDIMMs are also excellent at reducing latency and improving performance as a caching tier. By moving hot data writes to faster DRAM on the memory bus, applications that experience latency from writing hot data to slower media can benefit from NVDIMMs. Microsoft Storage Spaces was up to 2x faster with NVDIMMs as compared to using NVMe SSDs (80% reads/20% writes on 8GB NVDIMMs).
HPE NVDIMMs are ideal for eliminating write storage bottlenecks and are the fastest tier of storage on HPE ProLiant servers.
