Dell Technologies HPC Community Event
About the Event
Over the past several years, NVMe over Fabrics (NVMe-oF) has demonstrated a dramatic reduction in latency and increase in IOPS (compared to traditional storage networking protocols) and used this information to extrapolate the benefit it can provide to applications of all kinds.
Unfortunately, the more important questions have been left as an exercise for the buyer: “How does each transport type really impact application performance?” and “How does each transport type holistically fit into my environment?”
In addition, these performance comparisons have not taken into account the challenges, related to both basic connectivity and end-point discovery, that can make it difficult to use NVMe-oF in environments that require a high-degrees of automation.
For these and other reasons, Dell and several other companies have been collaborating on innovations that enable an NVMe-oF IP Based fabric to be centrally managed, enabling administrators to set policies that define the relationships between Hosts and the NVM subsystems they need to access. Once defined, these policies may be enforced by a Centralized Discovery Controller (CDC) that allow each Host to automatically discover and connect to only the appropriate NVM subsystems and nothing else.
This session will explore the use cases for each transport type and discuss where the use of centralized discovery makes sense.
About the Speaker
Erik Smith, Distinguished Member of Technical Staff, Dell Technologies
Erik Smith is a Distinguished Member of Technical Staff (DMTS) with Dell’s Integrated Products and Solutions CTIO team. He is currently focused on next generation Storage Networks and the creation of centralized storage services for NVMe-oF. Previously, Erik led Engineering and Advanced development for Dell’s Connectrix Business unit and was responsible for working with partners to address architectural problems and collaborate on new features. Most of Erik’s previous work was related to Fibre Channel and the avoidance of congestion spreading as well as the automation of fabric zoning by advocating for his favorite invention, Target Driven Zoning (TDZ). Erik also led the integration of Connectrix into Dell’s CloudIQ and initiated several proof-of-concepts related to Zero Touch Provisioning for OpenStack, and Software Defined Storage in general. Erik has authored several widely read techbooks related to Storage Networking and also has a fairly successful blog “Brasstacks” that provides real world actionable information for technology users of all kinds. Erik has 31 patents related to storage networking and automation (granted and pending).
