Sequent Computer Systems

Sequent Computer Systems, Inc. was a computer company that designed and manufactured multiprocessing computer systems. It was among the pioneers of high-performance symmetric multiprocessing open systems, innovating in both hardware, such as cache management and interrupt handling, and software, such as read-copy-update. Through a partnership with Oracle Corporation, Sequent became a dominant high-end UNIX platform in the late 1980s and early 1990s. Later it introduced a next-generation high-end platform for UNIX and Windows NT based on a non-uniform memory access architecture, NUMA-Q.
