Just like SCSI, NVMeoF installations rely on multiple network paths to maximize the throughput between the NVMe host and controller. And, just like any network, sometimes those paths fail. Come learn about how to recover from those failures in a way that leaves your data intact. And then learn about how to recover more quickly. This presentation will require a basic understanding of the NVMeoF protocol.

Abstract
Just like SCSI, NVMeoF installations rely on multiple network paths to maximize the throughput between the NVMe host and controller. And, just like any network, sometimes those paths fail. Come learn about how to recover from those failures in a way that leaves your data intact. And then learn about how to recover more quickly. This presentation will require a basic understanding of the NVMeoF protocol.
Learning Objectives
Describe the data corruption scenarios that correct recovery avoids.
Walk through the steps of recovery and identify the goal accomplished at each step.
Demonstrate optimizations to reduce the time and complexity of recovery.
