The Case for Mainframe Migration and Consolidation

April, 2006


Mainframe computers still occupy a major position in the hardware inventory of many data centers, especially in certain industries such as banking, finance, and insurance, and among larger companies. According to statistics collected in our annual IT spending survey, the economic performance of mainframes is not as good as that of other hardware platforms, especially in data centers where mainframe computers are used in a mix with other classes of servers. For organizations with such a heterogeneous server mix, these findings may be used to justify migration of mainframe applications to other server platforms or, at a minimum, undertake a mainframe server consolidation strategy.
