Paper Title: NVM Express Software Drivers Update
Paper Abstract: This talk provides an overview of the NVMe software drivers, including new updates and what is supported. The presenters will describe the vSphere support for NVMe and NVMe-oF technologies with an overview of the ESXi driver eco-system followed by an update of the various NVMe features support especially pertinent to NVMe-oF including VMware support for some of the NVMe-oF control plane features. The presentation will also feature an overview for NVMe support in the SPDK host driver and how the target continues to evolve in step with the NVMe specification and the storage industry. We will will then provide an overview of the significant additions and improvements over the last 18-24 months, including ZNS, multipath/ANA, automated discovery and vfio-user for NVMe virtualization. Updates will be provided on UEFI Device Drivers including NVMe related updates in UEFI Platform Firmware, Built-in Diagnostics, where and how the UEFI drivers fit in the NVMe Software Driver Eco-System and other resources to enable developers and NVMe device, software, and platform vendors. Finally, this session will provide updates to the Windows in-box NVMe drive.
