Xserve is de naam van Apple's 19-inch rackmountable server lijn. De introductie van de Xserve in 2002 was de eerste speciaal ontworpen server Macintosh sinds de Apple Network Server uit 1996. De eerste versie had 1 of 2 PowerPC G4 procesoren aan boord om later vervangen te worden door de PowerPC G5 procesoren. Op dit moment wordt de Xeon lijn processors van Intel gebruikt in het hart van de machine. De Xserve is uitermate geschikt als workgroup server en bied in samenwerking met Mac OS X Server bied het de mogelijkheden tot gebruikt als een Fileserver, Web server of in een cluster als high-performance computing platform. Speciaal voor dit doel heeft Apple de Xserve Node uitgebracht, een versie van de Xserve zonder ComboDrive of SuperDrive Ook heeft Apple een lange tijd de Xserve RAID aangeboden voor gebruikers met extra opslag behoeften.

Apple introduceerde de Xserve op 14 Mei 2002. Deze was uitgerust met één of twee PowerPC G4 processoren draaiend op 1GHz. De Xserve had ondersteuning voor 2 Gigabyte RAM met een 64-bit bus. De machine telt drie FireWire#FireWire 400 poorten en twee USB#USB 1.1 poorten. Voor connectiviteit is een gigabit en RS-232 interface voor extern beheer. Twee 64-bit/66 MHz PCI kaarten en één 32-bit/66 MHz PCI/AGP poorten waren aan wezig; in de basis configuratie.
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.
Initially, two configuration options were available: a single-processor Xserve with 256 MiB of memory at $2999 and a dual-processor Xserve with 512 MiB of memory at $3999. Both shipped with a single 60 GB disk and Mac OSX "Jaguar" Server.
On February 10 2003 Apple released an improved and expanded Xserve lineup. Improvements included one or two 1.33 GHz PowerPC G4 processors, two FireWire 800 ports (rear), faster memory (PC-2700), and higher capacity UATA/133 hard disk drives (80 or 160 GB). Also, the front plate was redesigned for a slot-loading CD-ROM. A new model, the Xserve Cluster node was announced at the same price as the single-processor Xserve, featuring two 1.33 GHz processors, no optical drive, a single hard drive bay, no video or ethernet cards, and a 10-client version of "Jaguar" server.
On April 2 2003 the Xserve RAID was introduced, providing a much higher capacity and higher throughput disk subsystem for the Xserve.

On January 6 2004 Apple introduced the Xserve G5, a redesigned higher-performance Xserve. The 32-bit PowerPC G4s were replaced with one or two 64-bit PowerPC 970 processors running at 2 GHz. Up to 8 GiB of PC-3200 ECC memory was supported on a 128-bit memory bus. One FireWire 400 port (front), two FireWire 800 ports (rear), two USB 2.0 ports (rear), an RS-232 management interface (rear), and two onboard gigabit ethernet ports (rear) with TCP offload provided greater connectivity. A 133 MHz/64-bit and a 100 MHz/64-bit PCI-X slots rounded out its expansion options. Ventilation issues restricted it to 3 SATA hot-swap drive bays (80 or 250 GB each), with the original space for the fourth drive bay used for air vents. The front plate and slot-loading optical drive (ComboDrive/Superdrive optional) were retained from the last Xserve G4.
Three configuration options were available: a single-processor Xserve G5 with 512 MiB of memory at $2999, a dual-processor Xserve G5 with 1 GiB of memory at $3999, and a dual-processor cluster node model (with an unchanged appearance from the G4 cluster node) featuring 512 MiB of memory, no optical drive, a single hard drive bay, and a 10-client version of "Panther" Server at $2999.
The higher memory capacity and bandwidth of the Xserve G5 as well as the stronger floating-point performance of the PowerPC 970 made it more suitable for high-performance computing (HPC) applications. System X is one such cluster computer built with Xserves.
On January 3 2005, Apple speed bumped the Xserve G5 with 2.3 GHz PowerPC 970 processors in the dual-processor configurations. 400 GB hard disks were made available for up to 1.2 TB of internal storage. The slot-loading optical drive was upgraded to a combination DVD-ROM/CD-RW standard, DVD-/+RW optional.
Recently, Apple updated the Xserve and Xserve RAID to allow the use of 500 GB Hard Drives.
Mac OS X Tiger Server is now available for the Xserve.

The Intel-based Xserves were announced at the Worldwide Developers Conference on August 7 2006. They use Inte Xeon 'Woodcrest' processors at 2 GHz, 2.66 GHz, or 3 GHz, FB-DIMM DDR2, ATI Radeon X1300 graphics, a maximum storage capacity of 2.25 TB when used with three 750GB drives, optional redundant power supplies and a 1U rack form factor. The Intel Xserves now have their graphics cards on-board, meaning that one does not need to sacrifice a PCI slot to add video capabilities --a departure from G4 and G5 Xserves.
On January 8 2008 Xserve was updated to use Intel Xeon 'Harpertown' processors at 2.8 GHz or 3 GHz, PC6400 DDR2 memory at 800 MHz, and a maximum storage capacity of 3 TB when used with three 1 TB drives. The front mounted FireWire 400 port featured in previous models was also replaced with a USB 2 port.
