Description¶
The TFTP servers will be used above all by the PXE clients during the boot phase. We therefore recommend to partition the TFTP servers via the configuration of the DHCP servers.We suggest to co-locate the TFTP and the DHCP servers and to allow for static load balancing thanks to a static DHCP configuration (via confiture).
The servers are configured via system sockets and in.tptpd, which are provided by the tftp-server package. The data will be stored on Gluster.
