'''Xserve RAID''' is a attachment mass-storage server that was offered by [[Apple Inc.]]

Xserve RAID held up to 14 hot-swappable [[Advanced Technology Attachment|Ultra-ATA]] hard drives, and had a capacity of 10.5&nbsp;[[Terabyte|TB]] when filled with 750&nbsp;[[Gigabyte|GB]] modules. Xserve RAID supported [[redundant array of independent disks|RAID]] levels of 0, 0+1, 1, 3 and 5 in hardware, hybrid RAID levels such as 10 and 50 could be created in software.<ref name="Users Guide">{{cite web |url=https://support.apple.com/MANUALS/0/MA603/en_US/XserveRAID_UserGuide.PDF |title=Xserve RAID User's Guide |publisher=[[Apple Inc.|Apple Computer Inc.]] |date=2003 |access-date=November 24, 2022 |url-status=live |archive-url=https://web.archive.org/web/20090206031850/http://manuals.info.apple.com/en/XserveRAID_UserGuide.PDF |archive-date=February 6, 2009 }}</ref> It was [[19-inch rack|rack-mountable]] and was 3[[rack unit|U]] high.<ref name="Users Guide"/>

Although the Xserve RAID contained 14 drives, they were split into two independent groups of 7 drives each managed by an identical RAID controller. Importantly, the controllers were independent, but not redundant; each managed seven of the storage array's fourteen drives, given a failure of one of the controllers those 7 drives were not accessible: the other could not take over its duties. Xserve RAID did, however, have redundant cooling units and power supplies. Xserve RAID's ports were two [[Fibre Channel]] ports for regular data transfer, a [[10/100]] Ethernet port for remote management, and a serial port for [[uninterruptible power supply|UPS]] communication via the [[Simple Signaling Protocol]].

Apple marketed Xserve RAID mainly as a companion to [[Xserve]] in [[file server]] and [[high-performance technical computing]] applications. The storage array is also useful in some environments such as [[non-linear editing system|non-linear video editing]]. Also, Apple certified Xserve RAID for use with some other vendors' servers, such as those running [[Windows Server 2003]] or [[Red Hat Enterprise Linux]]. Due to the cross-platform support available, users do not need a Mac to administer the Xserve RAID. Apple shipped a CD-ROM with the device containing the Xserve RAID Admin Tools, a [[Java Platform|Java]] software application that runs on most operating systems — including [[OS X]], [[Windows (operating system)|Windows]], [[Linux]], and [[Solaris (operating system)|Solaris]].

Xserve RAID was available in models costing between [[United States dollar|US$]]5,999 and US$10,999<ref name="PR20030210"/><ref name="PR20040106"/> (later US$12,999),<ref name="PR20041019"/><ref>{{cite press release |date= September 13, 2005 |title= Apple Updates Xserve RAID |publisher= [[Apple, Inc.]] |url=https://www.apple.com/newsroom/2005/09/13Apple-Updates-Xserve-RAID/ |access-date=November 24, 2022}}</ref> plus configuration and support options.

The Xserve RAID was discontinued on February 19, 2008.<ref name="MW">{{cite web |url=http://www.macworld.com/article/132164/2008/02/raid.html |title=Apple discontinues Xserve RAID |last=Dalrymple |first=Jim |date=February 19, 2008 |website=Macworld |publisher=[[International Data Group#Foundry|Foundry]] |access-date=November 25, 2022}}</ref>
