In December 1991, Cray purchased some of the assets of Floating Point Systems, another minisuper vendor that had moved into the file server market with its SPARC-based Model 500 line.

In spite of these machines being some of the most powerful available when applied to appropriate workloads, Cray was never very successful in this market, possibly due to it being so foreign to its existing market niche.
