Editing Sequent Computer Systems (section)

===IBM purchase and disappearance===
With their future product strategy in tatters, it appeared Sequent had little future standing alone, and was purchased by IBM in 1999 for $810 million.<ref>{{cite news |newspaper=Computerworld

The first was the x440 in August, 2002 with a follow-on x445 in 2003. In 2004, an Itanium-based x455 was added to the NUMA family. During this period, NUMA technology became the basis for IBM's [[IBM System x|extended X-Architecture]] (eXA, which could also stand for enterprise X-Architecture). As of 2011, this chipset is now on its fifth generation, known as eX5 technology.<ref>{{cite web |url=http://www.ibm.com/systems/info/x86servers/ex5/ |title=IBM eX5 flexible enterprise systems: EX5 systems overview |website=www.ibm.com |access-date=22 May 2022 |archive-url=https://archive.today/20130125221915/http://www.ibm.com/systems/info/x86servers/ex5/ |archive-date=25 January 2013 |url-status=dead}}</ref><ref>{{cite web|url=http://www.redbooks.ibm.com/Redbooks.nsf/pages/xref?Open|title = XREF: System x Reference &#124; IBM Redbooks}}</ref> It now falls under the brand [[IBM System x]].

According to a May 30, 2002 article in the ''[[Wall Street Journal]]'' (WSJ) entitled "Sequent Deal Serves Hard Lesson for IBM":
:When IBM bought Sequent, ...it [Sequent] lacked the size and resources to compete with [[Sun Microsystems|Sun]] and [[Hewlett-Packard|Hewlett-Packard Co.]] in the Unix server market....
:In 1999, IBM had problems of its own with an aged and high-priced line of [[Server (computing)|server]]s, particularly for its version of Unix known as [[AIX operating system|AIX]]. It also faced huge losses in [[personal computer]]s and declining sales in its cash-cow [[Mainframe computer|mainframe line]].
