The fact that VAXClusters were already going out of fashion by that time, and the fact of IBM's parallel sysplex existing by that time already negate your point.
previous $employer had built a globally distributed multisite c&c processing system twice by then and were in the process of revamping it for a 3rd.. 1st on mainframes & remote serial compute devices in the 80s, then on unix workstations in the early-mid 90s.
They were by far not alone in dealing with this level of complexity for the time.
