Introduction to DEM

Existing NVMe-oF Linux Implementation only supports local configuration Host and Target drivers must be manually (un)loaded through modprobe commands Hosts can either configure through /dev/fabrics or nvme-cli Targets can either configure through configfs or nvmet-cli

DEM Project provides

• Service scripts to automatically (un)load Hosts and Target drivers
• Remote configuration of NVMe-oF resources
• Resource enumeration for provisioning remote NVMe resources
• Asynchronous Event Notification of changes to provisioned remote subsystems

DEM Project supports NVMe-oF

• RDMA Transport
• TCP Transport
• In-kernel Host and Target drivers
• SPDK Target driver (as of Q4-2018)
