Here I like to show you my idea of a redundancy solution. After managing a LAMP for a few years with a solid RAID solution I came to the idea that not only the disks are a risc, but all hardware is. Also I wanted to move to a enery-friendly solution: low-power cpu's that don't need a cooling fan. I set up a system of two (or more) redundant fanless mini pc's that can run the different elements of a LAMP. Any minipc or virtual server can run as a 'brick'.


I split the functions of the LAMP in a few services:

  • mail (postfix, dovecot, antispam, antivirus)
  • web (apache, squid)
  • homes (samba, nfs)
  • named (bind)
  • dhcp (dnsmasq, bootp, tftp, nfs)
  • music (subsonic)

Some services run always on any brick: ntp, cups
