Triple-architecture clusters of VAX, Alpha and Integrity Itanium
systems have been tried and found to work at various sites.
In my admittedly somewhat spotty recollection, the OpenVMS Cluster
V8.3-1H1 Software Product Description (SPD; <http://docs.hp.com/>) has
softened the wording around the lack of support in this area, too.
While not supported as far as warranty support or migration support
and explicitly not supported for production use, apparently HP is
building some confidence in the operations of these configurations.
This based on the wording in the current SPD.
Would this be supported by HP? No. Not beyond the wording present in
the OpenVMS Cluster SPD; not without some sort of specific support
statement from HP.
But will it work well enough for an emulated VAX to join into a
hobbyist cluster such as Deathrow? Probably yes. I see no reason
not to try it here, and (on no evidence) would tend to expect issues
arising with the emulation and less so with the clustering. (There's
been an oddity or two here.) Would I run this triple-architecture
configuration in production? I'd certainly think about it, if I
really needed a VAX and had no way to VEST/AEST/translate or to port
the application code involved. The obvious acceptance testing - in
the absence of site-local and application tests or of the readily-
available collection of excessively creative users commonly found on
the Deathrow cluster - would be to crank up multiple parallel passes
But I'd not expect HP to support any problems that might be found.
