NVMesh software helps AI, ML, and database storage

Data centre technology, whether for public clouds, private clouds or enterprise data centres, has just taken a tremendous step forward with significant impact for AI, ML and database storage thanks to new technology in Excelero’s NVMesh software.

With the debut of Intel’s new P5800X SSD, the 2nd Gen Optane SSD, IT teams have a new option for maximising scale-out storage performance, scalability and for optimising price-performance.  Excelero is tremendously excited to participate in this dramatic new technology launch as the only software-defined storage provider working with Intel to showcase ‘knock-your-socks-off’ performance.

For the past year, Excelero has been working closely with Intel on using 2nd Gen Optane technology to make our NVMesh solution deliver even more for demanding applications such as artificial intelligence, high performance computing, databases and data analytics. With double the density and an upgraded PCIe gen 4.0 interface, the P5800X delivers at least a 2.5x performance boost for storage bandwidth, throughput and stable low latencies even in the most demanding scenarios.

When combined with Excelero NVMesh’s scalable distributed erasure coding (EC) for data protection, data centres can obtain unparalleled high throughput and low latency with even a minimal configuration, as shown in this demo (LINK). As tested, NVMesh delivers the performance of proprietary all-flash arrays at a fraction of the cost, in a server using just two Optane P5800Xs and six QLC drives, specifically here Intel QLC P4326 drives, providing 60 TBs of usable protected storage space.

NVMesh’s performance scales linearly with cluster size and its distributed EC provides dual-protection from drive and node failures. Imagine the performance and especially the performance density that can be achieved with such building blocks at data centre-scale.

Assuring high-performance storage for demanding applications has usually required proprietary storage systems with significant complexity and cost. Such closed systems cannot keep up with the pace of storage growth and the need to support newer and better technologies without forklift upgrades.

For AI, HPC, data analytics and database workloads, the combination of Intel P5800X SSDs and Excelero NVMesh software means the price tag required for the storage to feed hungry applications will become far less of an issue. For our customers, combining the Excelero NVMesh and Intel P5800X SSDs means:

  • Customers can benefit from Excelero’s high performance distributed erasure coding technology with any NVMe drive efficiently, including QLC drives.
  • Demanding applications can get write performance with the NVMesh distributed erasure coding data protection in addition to the strong read performance and space efficiency they are used to and value.
  • Customers can handle mixed read-write workloads, from small files to large streams, with very high efficiency and without interference between them.

For years, data centre architects have wanted to have it all with their demanding applications, to replace enterprise triple-layer cell (TLC) SSDs with cost efficient and capacity optimised QLC drives, while obtaining top performance, reducing total cost of ownership, optimising system longevity and maintaining NVMe elasticity.
