NVMFT(4) Kernel Interfaces Manual NVMFT(4) NAME nvmft -- NVM Express over Fabrics CAM Target Layer frontend SYNOPSIS To compile the subsystem into the kernel, place the following lines in the kernel configuration file: device nvmft device ctl Alternatively, to load the subsystem as a module at boot time, place the following line in loader.conf(5): nvmft_load="YES" DESCRIPTION The nvmft driver provides the kernel component of an NVM Express over Fab- rics controller. The NVMeoF controller is the server exporting namespaces backed by local files and volumes to remote hosts. nvmft follows the dy- namic controller model and creates a new dynamic controller for each asso- ciation. nvmft is implemented as a ctl(4) frontend and exports CAM Target Layer LUNs as namespaces to remote hosts. LUNs can be configured via ctladm(8). Associations between the local controller and remote hosts are managed us- ing both the nvmfd(8) daemon and the ctladm(8) utility. The nvmfd(8) dae- mon listens for new associations and handles transport-specific negotiation before handing off connected queue pairs to nvmft which associates queue pairs with a suitable controller instance. The nvlist ctladm(8) command lists active controllers. The nvterminate command terminates one or more associations between a local controller and a remote host. Associations require a supported transport such as nvmf_tcp(4) for associa- tions using TCP/IP.
