IBM ES/9000 family
IBM ES/9000 is the family of IBM mainframes, introduced in 1990, as the first implementations of the ESA/390 architecture, and developed to accommodate VSE/ESA, VM/ESA and MVS/ESA operating systems. New hardware features included implementation of ESCON fiber optic channels. ES/9000 family was introduced directly after ESA/370-based models, such as IBM ES/3090, IBM ES/4381, and inherited such hardware features as expanded storage, logical partitioning (LPAR), and optional vector facilities (vector co-processors).
