FUD certainly has its place in the sale but there is a real benefit in
that you can keep things humming when you take one box down for backups,
PTF's. IPL, etc. Depends on the business requirements (as usual).
I don't have the luxury of HA but I can see the need. Of course, I also
see the need since we live in earthquake country but that's another
story.

Walden,
To your first answer... sounds like a beehive or the borg, but seriously
you can do essentially the same thing with a properly configured i5 or
mainframe with partitioned DB and LPARs.
As to your first answer... I'll wager most often data replication
companies are doing well because of the greatest tool in a salesman's
kit bag... FUD (Fear, uncertainty and doubt).

For their needs, they should have gone with the i5 or better, MVS, to
scale both ways all
on one box, not 3,000; how dumb but that's PC thinking.
Not necessarily... this way they can deploy, change, upgrade, and even
bring-down (intentionally or unintentionally <G>) only part of their
system.
It's funny. On the midrange-l list there's a conversation about RAID and
how we can blow a drive, and hot swap it w/out data loss and the users
aren't any the wiser. However, when we want RAIWS (Redundant Array of
Inexpensive Web Servers) we're told it's a dumb way to do things and we
should all have a single-point-of-failure system. If the System i never
crashes and has 100% uptime, why are the data replication companies
doing so well? <G>
