Eric - Compaq holds about 70% of the key patents in the clustering arena. Clustering divided early on (20 years ago) into several camps - the main ones were "shared nothing" (with Tandem as the key advocate) and "shared storage" (with DEC as the leader). VAX clusters defined the successful general purpose cluster environment while Tandem defined the high performance cluster. These two companies enjoyed absolutely dominant share in their respective markets, approaching 80% and in some markets 90%. Even today those architectures represent about 60% of all installed clusters. Of the remaining cluster technology, IBM holds patents on about half, maybe 15% of the outstanding work, and splinter outfits like Stratus (ISIS systems) have most of the rest. So with the acquisition of Tandem and DEC, CPQ got virtually all of the general purpose cluster technology worth having, plus most of the customers using that technology.
