The iSeries is vertically scalable (it can grow from very small to very
large).  Intel solutions are horizontally scalable.  You can add many,
many machines in a cluster.  Current thinking is that you can achieve
greater reliability, uptime and performance at a much cheaper price with
the clustered solution.  Andrew Borts posted some interesting information
on this a while ago.

The scalability issue deserves context however.  Do you need
eBay/Amazon-type availability and performance, or are you web-enabling
internal apps and want them just as "available" as the 5250 versions were?
 I think most of us are dealing with the latter case, and in that scenario
a single iSeries server is still probably the best solution, IMHO.
