This is the standard proceedure when running a moderate sized ISP. For a
large ISP you will probably have 4 Ethernet ports on each machine.
1) Front-end VLAN (connection to the Internet).
2) Back-end VLAN (talking to file-servers etc).
3) Management VLAN (for you to login, and for backups).
4) Spare port in case one of the others breaks - also you can buy 1, 2, or 4
port Ethernet cards so you may as well get 4 port cards.

It's a good idea, but it's not really like a SAN.

Give your front-end VLAN with Internet IP addresses.
Give your back-end VLAN one series of private addresses - 10.0.0.0/8
Give your management VLAN another series of private addresses -
If you can't program in C, PERL, and shell scripts then don't call yourself a
Unix administrator. Every idiot on the net is claiming to be a Unix admin. :(
