The Fusion ioMemory platform accelerates enterprise applications such as databases, virtualization, cloud computing, big data by integrating hardware and software to overcome the limitations of legacy architectures and specialized hardware.〔(【引用サイトリンク】title= About Company )〕 ==History== The company was founded in December 2005 as Canvas Technologies in Nevada. Co-founders were David Flynn and Rick White. The company is based in Cottonwood Heights, Utah, near Salt Lake City. In June 2006 the company name was changed to Fusion Multisystems, Incorporated. A product with the brand name ioDrive was demonstrated and announced in September 2007. In March 2008, Fusion-io raised $19 million in a Series A round of funding from a group of investors led by New Enterprise Associates. David Flynn was chief technology officer, while Don Basile was chief executive officer at the time.〔 Michael Dell invested in Fusion-io during this round.〔 In 2009 and 2010, computer industry veteran, David Bradford, served as CEO. http://www.networkworld.com/article/2266925/data-center/fusion-io-lands--47-million-to-ramp-up-development-of-flash-storage.html In February 2009 it hired Apple Inc. co-founder Steve Wozniak as chief scientist.

A third round of funding led by Meritech Capital Partners, with additional capital from Accel Partners and Andreessen Horowitz, provided a total of $45 million in April 2010. It was named the second most promising information technology company by ''The Wall Street Journal'' in March 2010.

On August 5, 2011, Fusion-io acquired IO Turbine for about $95 million.〔(【引用サイトリンク】title=After Strong IPO, Fusion-io Buys IO Turbine For About $95M )〕 IO Turbine's main product was the ioTurbine hybrid array (caching to flash) software, which is virtualization-aware, particularly of VMware environments.〔http://www.theregister.co.uk/2013/12/17/fusionio_makes_ioturbine_slicker/〕〔http://www.pcworld.com/article/2042805/fusionio-updates-ioturbine-to-aid-more-types-of-onserver-caching.html〕 In January 2012, Fusion-io achieves a record breaking billion IOPS from eight servers at the DEMO Enterprise event in San Francisco.

At Storage Field Day 3, Fusion-io announced their acquisition of NexGen Storage in April 2013 for $114 million cash and $5 million in stock. NexGen was located in Louisville, Colorado and had a product it called n5, which it announced in November 2011 and upgraded in July 2012. The n5 was a hybrid product including hard disk drives as well as flash memory, aiming to provide more consistent performance guarantees than only disks. The n5 was renamed ioControl hybrid storage after acquisition. In May 2013 the co-founders David Flynn (CEO) and Rick White (CMO) left. In October 2013 Dennis Wolff, its CFO, was leaving.〔(Fusion-io Plunges Most Ever After CEO, Co-Founder Resign ), Bloomberg, 2013-05-08.〕〔(More Bad News From Steve Wozniak's Fusion-IO: A Crummy Outlook And The CFO Is Leaving ), Business Insider, 2013-10-23.〕 In November 2013 the Btrfs developers Chris Mason and Josef Bacik left Fusion-io for Facebook.〔(Leaving Fusion-io ), Chris Mason, 2013-11-27.〕〔(Josef Backik leaving Fusion-io ), 2013-11-27.〕 A scalable multi-queue block layer for the Linux kernel has been developed by Fusion-io engineers Jens Axboe and Shaohua Li, and merged into the Linux kernel mainline in kernel version 3.13, released on 19 January 2014. This new block layer leverages the parallelism (and thus provides much higher performance) offered by SSDs using NVM Express. With the release of Linux kernel version 3.13, only the virtioblk driver has been modified to actually use this new interface; other drivers will be ported in the following releases. A technical presentation paper of this new feature was previously published at ACM SYSTOR'13. In January 2014, Jens Axboe announced he was leaving Fusion-io to join Facebook.〔(Leaving Fusion-io ), Jens Axboe, 2014-01-24.〕 In June 2014, SanDisk announced its intentions to buy Fusion-io, with the deal expected to close in the third quarter of the year.〔(SanDisk to buy Fusion-io to boost flash storage business ), Reuters, 2014-06-16.〕 SanDisk completed its acquisition of Fusion-io in July 2014.〔(Sandisk completes acquisition of Fusion-io ), Sandisk, 2014-07-23.〕 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「Fusion-io」の詳細全文を読む スポンサード リンク
