If your budget is less than $10K, don't even bother to try to set up a fault-tolerant cluster; you're better off spending more on a high-quality single machine with RAID-1 or -10 disk config, hot spare drive, and dual power supplies...and tape backup, most importantly. Trying to implement a highly reliable cluster on cheap hardware is almost certainly going to prove futile or even counterproductive. How are you going to handle a split-horizon condition? -- -Chuck
