Now that NVMe™ has ratified TP4159 PCIe® Infrastructure for Live Migration, it is time to show the final details of how NVMe controllers in direct attached PCIe SSDs can be migrated from one server to the next for use cases such as workload balancing and maintenance. In this presentation I will detail the new commands, new events, new queues, updates to existing commands, and vendor specific options. This presentation will cover how a host utilizes the new protocol to migrate a controller. There will be example implementation options for the developed controllers supporting this new capability. Included will be error scenarios and the effects of resets.
If you write host software dealing with Virtual Machines, then this presentation is for you. If you are NVMe PCIe SSD supporting multiple NVMe controllers (i.e., multiple physical functions or SR-IOV), then this presentation is for you.
Oh, this new functionality can support other use cases for example Snapshotting, and maybe more.
