Xserve was a line of rack unit computers designed by Apple Inc. for use as servers. When the Xserve was introduced in 2002, it was Apple's first designated server hardware design since the Apple Network Server in 1996. It initially featured one or two PowerPC G4 processors, but was later switched over to the then new PowerPC G5, and subsequently switched again to two quad-core Intel Nehalem microprocessors.

The Xserve can be used for a variety of applications, including file server, web server or even high-performance computing applications using clustering – a dedicated cluster Xserve, the Xserve Cluster Node, without a video card and optical drives was also available. On November 5, 2010, Apple announced that the Xserve line would be discontinued on January 31, 2011 and replaced with the Mac Pro Server and the Mac Mini Server.

Apple introduced the Xserve on May 14, 2002 (released in June). Originally, it had one or two PowerPC G4 processors running at 1.0 GHz and supported up to 2 GB of PC-2100 memory on a 64-bit memory bus. Three FireWire 400 ports (one in front, two in rear), two USB 1.1 ports (rear), an RS-232 management interface (rear), and a single onboard Gigabit Ethernet port (rear) were provided for external connectivity. Two 64-bit/66 MHz PCI slots and one 32-bit/66 MHz PCI/AGP slot were provided; in the default configuration the two PCI slots were filled with an ATI Rage video card and an additional gigabit Ethernet card. Up to 4 UATA/100 hard disk drives (60 or 120 GB) fit into hot-swap bays in the front, allowing software RAID-0 and 1 arrays to be created. A tray-loading CD-ROM drive was mounted in the front.

Steven Paul "Steve" Jobs (/ˈdʒɒbz/; February 24, 1955 – October 5, 2011) was an American businessman, designer and inventor. He is best known as the co-founder, chairman, and chief executive officer of Apple Inc. Through Apple, he was widely recognized as a charismatic pioneer of the personal computer revolution and for his influential career in the computer and consumer electronics fields. Jobs also co-founded and served as chief executive of Pixar Animation Studios; he became a member of the board of directors of The Walt Disney Company in 2006, when Disney acquired Pixar.

In the late 1970s, Apple co-founder Steve Wozniak engineered one of the first commercially successful lines of personal computers, the Apple II series. Jobs was among the first to see the commercial potential of Xerox PARC's mouse-driven graphical user interface, which led to the creation of the Apple Lisa and, one year later, the Macintosh. During this period he also led efforts that would begin the desktop publishing revolution, notably through the introduction of the LaserWriter and the associated PageMaker software.
