But a cluster would also help if a machine fails... see your PIII 1000Mhz
with 1Gb memory and 20Gb LVD drive is useless if the machine fails which is
why I though of a cluster.
Apparently as cluster can handle a machine failing but just starts to slow
down... I may be wrong and just heard somewhere...

The real question is how much is it going to grow?
If not, then you would probably find a hardware upgrade easier;
CPU to PIII/Athlon,
RAM to 512MG/1024MB,
Hard disk to SCSI-3 on LVP
Would a dual CPU help?
It is a lot easier to have one machine, than mulptiple
machines/problems.
Raid fails for a reason - what is it?

If it is going to grow, then clustering might solve your problems if a
cluster can serve the demand. There are some good Linux Journal
solutions to various real world problems. You might find some answers
there, or at least tips.
Probably a waste. Is it 100Mb now? What is the faster backpane switch
that you can get - I've seen great network plans die because the
switch backplane speed wasn't that fast.
Is dual porting the box possible?
I'd suggest you really find out what the cause of the problems are
before any money is spent.
I once saw a system 60Gb (15 x4Gb Fast Wide) system that had data
errors and it turned out the whole kit and caboodle was jammed under a
CAD L desk with full modestry skirt and sides and almost nil
ventilation in the general office. Worked great in winter and lousy in
summer. What was required was forced ventlation under the dest and
extra booster fans in the external SCSI boxes (about $200 at the time)
= problem solved.
