About this talk

NVMe® IP-based SANs (including TCP, RoCE, iWARP) have the potential to provide significant benefits in application environments ranging from the Edge to the Data Center. However, before we can fully unlock NVMe IP-based SAN’s potential, we first need to overcome the NVMe over Fabrics (NVMe-oF™) discovery problem. This discovery problem, specific to IP based fabrics, can result in the need for Host administrators to explicitly configure each Host to access each of the NVM subsystems in their environment. In addition, any time an NVM Subsystem interface is added or removed, the Host administrator may need to explicitly update the configuration of impacted hosts. This process does not scale when more than a few Host and NVM subsystem interfaces are in use. Also, due to the de-centralized nature of this process, it also adds complexity when trying to use NVMe IP-based SANs in environments that require a high-degrees of automation. For these and other reasons, several companies have been collaborating on innovations that simplify and automate the discovery process used with NVMe IP-based SANs. During this session we will explain: • NVMe IP-based SAN discovery problem • The types of network topologies that can support the automated discovery of NVMe-oF Discovery controllers • Direct Discovery versus Centralized Discovery • An overview of the discovery protocol After you watch the webcast, check out the Q&A blog: https://bit.ly/3nI8Tk4
