Out of curiosity, have you considered PXE (network) booting, and
mounting the file system entirely over NFS?  An SSD seems relatively
expensive for essentially just holding the OS and log files.  The
master backend can be used as the NFS server and the PXE server (i.e.,
DHCP and TFTP servers) -- putting all the services on the master
backend since the frontend probably isn't much use without the
backend.
