MICROSOFT SQL SERVER 2019 WITH HPE NIMBLE STORAGE AND STORAGE CLASS MEMORY POWERED BY INTEL OPTANE SSDS New NVMe cache increases performance for demanding online transaction processing Lab verified benefits of Storage Class Memory powered by Intel Optane SSDs show back-end latency reduced as much as 50%
HPE Nimble Storage
Growing enterprise data continues to drive the need for increased system performance. However, many companies are limited in data center cage space, power, or system footprint. Some simply don’t want to increase the number of devices they need to deploy and manage. By incorporating the latest acceleration technology—in this case, Storage Class Memory (SCM) in the form of Intel® Optane™ solid state drives (SSDs)—system performance can be increased without expanding the system footprint or administrative overhead. Demanding Microsoft SQL Server workloads, especially those running online transaction processing (OLTP) applications, can immediately benefit from a high-performance caching layer that reduces read latency and speeds overall system responsiveness and performance.

SCM, consisting of Intel Optane SSDs, adds a caching layer that improves storage performance and represents the future of low-latency, persistent storage media.
It closes the performance gap between dynamic random-access memory (DRAM) and NAND flash solid-state drive storage. HPE Nimble Storage now supports SCM powered by Intel Optane SSDs, which fills this gap and increases the performance of business workloads, especially SQL Server. The Intel Optane SSD-based cache within HPE intelligent storage becomes the high‑performance tier for frequently used data blocks. This tiering is handled automatically by the array—no additional administration or configuration is required by the system administrator or DBA. Figure 1 is taken from lab testing, which showed the significant storage read latency reduction for the database when using SCM. Back-end storage system read latencies decreased by as much as 50%, which translated to a 35% performance benefit at the host server.1
