Remember that IBM already has its own clustering.

Well, yes and no. HACMP is not clustering as we OpenVMS people know it,
it's really more "fail-over detection and initiation" when one system in
a "cluster" fails. It also relies on storage infrastructure for "heart
beat" rather than network infrastructure. Kinda bizarre, but then HACMP
began life as a third-party product (read: kludge).

VMS clustering is "shared almost everything".

AIX clustering is "shared nothing", neither is there a simple way to
execute commands on every member of a cluster ala SYSMAN's DO command.

Remember that Palmer
donated clustering IP to Microsoft and to Oracle.

It seems, however, that only Oracle truly took the ball and ran with
with it.
