Parallel Enterprise Server
An earlier family of S/390 (System/390) mainframes from IBM that were air cooled and used CMOS-based microprocessor technology (a CPU on one chip). Introduced in 1994 as the 9672 series, Parallel Enterprise Servers rapidly replaced the earlier water-cooled, bipolar machines that were considerably larger and more power hungry.Parallel Enterprise Servers employed symmetric multiprocessing (SMP) and up to 32 servers could be tied together in a Parallel Sysplex cluster. See IBM mainframes and Parallel Sysplex.
