The Non-Volatile Memory Express (NVMe) storage interface was created to connect high-performance storage media through faster, parallel PCI Express lanes. But as you develop your storage strategy for 2019 and beyond, it pays to take a look at NVMe and SCM as well as traditional flash arrays. As with tiering, the intelligence of the algorithms is key to delivering great results in production environments. artificial intelligence and machine learning, NVMe-oF Delivering While Persistent Memory Remains Mostly a Promise, DCIG to Publish TOP 5 Reports Covering Software-defined Storage, DCIG 2020-21 TOP 5 High-End Storage Arrays Report Now Available, Vendors are Focused on Improving the Enterprise Storage Ownership Experience, Five Important Advances in All-Flash Array Technology, Four Paths on the Journey to Automated Enterprise Infrastructure, Four Advances in Storage Technology that are Redefining High-End Storage, Six Implications of the IBM FlashSystem Announcement, Three Advances in Enterprise Storage Transforming the Ownership Experience, How Enterprise Storage Arrays are Adapting to Meet Changing Business Requirements, DCIG Will Provide Update on All-flash Array Advances at Flash Memory Summit 2019, DCIG 2020-21 TOP 5 Azure Cloud Backup Solutions Report Now Available, DCIG 2020-21 TOP 5 SME AWS Cloud Backup Solutions Report Now Available, DCIG 2020-21 TOP 5 Enterprise AWS Cloud Backup Solutions Report Now Available, Sub-200 microseconds of latency for most IO, Nearly 100% of IO in under 300 microseconds. While NVMe continues to drop in price, sometimes giving SATA SSDs a run for their money, SATA SSDs often come out on top. By continuing to use this site, you consent to our use of cookies. Short for NVM Express or Non-Volatile Memory Express, NVME is a host controller interface specification that uses the PCI Express (PCIe) bus to connect SSDs to a server. Let us show you how faster, more efficient storage technologies can help you meet the performance demands of today’s applications. However since market conditions change, the information and recommendations are made without warranty of any kind. 3D XPoint was jointly developed by Intel and Micron. As new applications have been introduced and performance demands have increased, the drawbacks of using HDD interfaces for flash storage have become increasingly evident. Storage Resource: What is NVMe? This is the first in a series of articles about Persistent Memory and its use in enterprise storage. The standard is maintained by SATA-IO, or the Serial ATA International Organization, a nonprofit formed in 2004. I also favor caching because I believe it will bring the benefits of SCM within reach of more organizations. How NVMe and Storage Class Memory Meet Today’s Application Demands, As new applications have been introduced and performance demands have increased, the drawbacks of using HDD interfaces for flash storage have become increasingly evident. It can pump data at breakneck rates compared to SATA and at lower latency, providing brisk performance and enabling businesses to tackle demanding storage workloads that may have given them pause in the past. SATA SSDs may boast blazing storage performance compared to their HDD cousins, but NVME SSDs can smoke them both by a wide margin. Once SCM has been added to the array, Dell EMC’s fully automated storage tiering (FAST) technology will monitor array activity and automatically move the most active data to the SCM tier and less active data to the flash memory SSDs. HPE is one of many vendors taking the caching path to integrating SCM into their products. Anyone who has tinkered around computers long enough will remember the flat and wide ribbon-like cables used in PATA connections compared to the thin SATA cables that are easier to handle. Dell EMC announced that it will soon add Optane-based storage to its PowerMAX arrays, and that PowerMAX will use Optane as a storage tier, not “just” cache. In addition, data can be accessed at the byte level as well as the block level, making SCM more flexible.
