NVMe over Fabrics (NVMe-oF) is the concept of using a transport protocol over a network to connect remote NVMe devices. nvme-stas contains services to be used to access NVMe over TCP:

* Storage Appliance Finder (stafd): automatically locate Central or Direct Discovery Controllers (CDC, DDC) with zeroconf (mDNS).

* Storage Appliance Connector (stacd): setup the I/O controller connections to each storage subsystem.
