  • TR-4684: Implementing and Configuring Modern Sans with Nvme/FC
    Technical Report Implementing and Configuring Modern SANs with NVMe/FC Michael Peppers, Martin George, NetApp December 2020 | TR-4684 | Version 5 Abstract NVM Express (NVMe) is a data storage protocol that delivers the fastest response times for business-critical enterprise applications. However, NVMe is more than a storage specification; the broader NVMe over Fabrics protocol encompasses the entire data path, from server to network to storage system. This technical report focuses on building modern SANs on NVMe over Fabrics, especially NVMe over Fibre Channel (NVMe/FC, also known as FC-NVMe). This document describes the industry-first NVMe/FC implementation in NetApp® ONTAP®, includes guidelines for SAN design and implementation, and provides links to testing and qualification recommendations.
