(Sequent Computer Systems, Inc., Beaverton, OR, www.sequent.com) A computer company founded in 1983 by 17 ex-employees of Intel that specialized in multiprocessing systems for the client/server environment. Sequent pioneered adapting SMP to Unix and was a leader in the high-end Unix market.
Sequent's SMP machines were all Intel based and were scalable up to 30 Pentium processors. Its Symmetry series ran the Unix-based DYNIX/ptx operating system, and the WinServer series ran Windows NT. Its NUMA-Q 2000 line, introduced in 1996, scaled up to 252 processors. In 1999, Sequent was acquired by IBM; by 2005, the Numa-Q servers and Symmetry line were on a migration path to IBM's pSeries, xSeries and TotalStorage offerings.
