Spectrum Scale with NVMe-over-Fabrics: Deploying NetApp EF600

NVMe-over-Fabrics on InfiniBand networks makes the Spectrum Scale “SAN Mode” available to HPC and AI clusters. This deployment model, which is popular in enterprise Fibre Channel SAN networks, does not require any Spectrum Scale NSD servers as all application nodes can directly access all block storage volumes over the fabric. This guide shows how to use the NetApp EF600 storage system in a Spectrum Scale “SAN Mode” setup, using NVMe-over-Fabrics on InfiniBand.

This Planning and Implementation Guide is intended for sales and technical sales specialists, solution architects, and storage administrators who want to deploy NVMe-over-Fabrics storage solutions like the NetApp EF600 with IBM Spectrum Scale. The paper will be most useful for technical professionals who have a working knowledge of high-performance storage systems.
