Fedora: \verbatim dnf install libibverbs-devel librdmacm-devel \endverbatim Ubuntu: \verbatim apt-get install libibverbs-dev librdmacm-dev \endverbatim Then build SPDK with the NVMf target enabled, either by editing CONFIG to enable CONFIG_RDMA or enabling it on the `make` command line: \verbatim make CONFIG_RDMA=y \endverbatim \section nvmf_config Configuring NVMf An NVMf specific configuration file is used to configure, or 'provision', the NVMf target. This file defines the following: - general application parameters - global NVMf parameters - ports that define local RDMA interface ports the nvmf target will use for network access - initiator groups with names and addresses to allow access to nvmf target subsystems - list of NVMe HW device candidates to share via NVMf - NVMf target subsystem(s) that define the provision mappings between remote initiator groups and local target ports, and NVMe device namespaces An example nvmf configuration file included with this package at `etc/spdk/nvmf.conf.in`. You must edit a version of this file for use in your environment and copy it to /usr/local/etc/spdk/nvmf.conf. Alternatively, you may also specify the configuration file explicitly using `-c /path/to/nvmf.conf` when starting `nvmf_tgt`. The `Port` and `Host` sections must be updated in all cases to match the IP addresses in your network environment. The `Nvme` section must also be updated with a the list of NVMe devices that will be exported. Each device is identified by a PCI bus, device, and function. The NVMf target will display a list of NVMe devices discovered in the system. This information can then be used to select the list of devices to populate this configuration file section. */
