The Dell PowerEdge (PE) line is Dell's server computer product line. Most PowerEdge servers use the x86 architecture. The early exceptions to this, the PowerEdge 3250, PowerEdge 7150, and PowerEdge 7250, used Intel's Itanium processor, but Dell abandoned Itanium in 2005 after failing to find adoption in the marketplace.〔(Dell to Phase Out Computers Using Intel's Itanium ) 〕 The partnership between Intel and Dell remained close, with Intel remaining the exclusive source of processors in Dell's servers until 2006. In May 2006 Dell announced that it also intended to develop servers using AMD Opteron processors.〔 (Press Release — Dell's International And Enterprise Business Drives First Quarter Revenue Growth ) 〕 The first Opteron-based PowerEdge systems, the PowerEdge 6950 and the PowerEdge SC1435, appeared in October 2006〔 (Press Release — Dell Unveils Four- and Two-Socket Servers ) 〕 PowerEdge machines come configured as tower, rack-mounted, or blade servers. Dell uses a consistent chip-set across servers in the same generation regardless of packaging,〔 (Dell Extends the Scalable Enterprise with Eighth-Generation PowerEdge Servers )〕 allowing for a common set of drivers and system-images. Original equipment manufacturers (OEMs) and value-added resellers also offer solutions based on PowerEdge servers. Loaded with custom software and with minor cosmetic changes, Dell's servers form the underlying hardware in certain appliances from IronPort,〔Dell Case-studies on the IronPort Email-security Appliance:(Partners in Stopping Crime ), February 2006, retrieved 28 June 2011〕 Google,〔Dell Case-studies on the Google Search Appliance: (- In Search Mode ), June 2007, retrieved 28 June 2011〕 Exinda Networks,〔ITWorld Canada website: (Quad CPUs gives Exinda WAN optimization a kick ), 21 July 2010, visited 28 June 2011〕 and Enterasys.〔Dell Case-studies: (Enterasys- Serving up Security )〕 In 2007 the PowerEdge line accounted for approximately 15% of Dell's overall revenue from computer-hardware sales.〔 (Press Release — Dell Reports Preliminary Revenue of $14.4 Million )〕 In subsequent years Dell made the transition from a pure hardware vendor to a solutions-provider and services company, as evidenced, for example, by the acquisition of Perot Systems and KACE Networks〔Blog of Kristen Mathis (What Dell-Perot merger means for IT ), 28-2-2010, visited 28 June 2011〕 and the setup of a special global services department within Dell〔PCWorld (Dell Launches Dedicated Services Organization ), December 2009, visited 28 June 2011〕 ==PowerEdge RAID Controller== Dell uses the name PowerEdge RAID Controller (PERC) for proprietary versions of its RAID computer storage controllers. The related software in the PERC Fault Management Suite offered facilities such as the Background Patrol read, which aims to fix bad sectors on online RAID disks running under some of the PERC controllers around 2006.〔 Dell licences its PERC technology from LSI. 〕 These cards were equipped with hardware from LSI Corporation or Intel, 256 MBytes of memory (upgradeable on the 5/i to 512 MB), support up to 8x SATA 3.0 Gbit/s drives without the use of expanders. They had an optional Battery Backup Unit (BBU) to allow more flexible use of the memory during writes, enhancing performance in RAID5 and 6, and operate over the PCI Express interface. 〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dell PowerEdge」の詳細全文を読む スポンサード リンク
