This is a discussion I had with lmb on #drbd yesterday. Please, "not
running professional systems" and high availability don't exactly go
together. With DRBD and Linux and Pacemaker your HA cluster will most
likely be way cheaper than with our proprietary, vendor-lock-in
counterparts, so please try to convince your boss to put some of those
savings in good hardware. He or she will thank you afterwards for having
made a better investment and still have saved a ton of cash in total.

Now for those who pull this discussion from the list archives, here's
the permalink to that post:
