Cirtas Systems was a privately held company based in San Jose, California. The company was founded in 2008, raised US$32.5 million in private funding, and shut down its operations in 2011.〔(Cloud Storage Startup Cirtas Retreats ). April 21, 2011〕 Its primary product, the Cirtas Bluejet Cloud Storage Controller, was a cloud storage gateway device that used public cloud storage utilities, such as Amazon S3, the Iron Mountain Archive Services Platform, AT&T Synaptic Storage as a Service and EMC Atmos for storing business data while maintaining enterprise storage array performance and functionality.〔GigaOm, Show Me the Gateway — Taking Storage to the Cloud, By Gary Orenstein Jun. 22, 2010 ()〕〔Storage Newsletter, Start-Up's Profile: Cirtas Systems, By Jean-Jacques Maleval Jun. 9, 2010 ()〕〔SearchStorage, What's keeping data storage out of the cloud?, By Chris Griffin ()〕 Cirtas’s Bluejet Cloud Storage Controllers were targeted at the enterprise market, with pricing starting at about $70,000 per device.〔Goldfisher, Alastair: Cloud storage company Cirtas raises $22 million. Reuters, January 26, 2011〕 On September 20, 2010, Cirtas emerged from stealth mode at the Storage Decisions, announcing its Bluejet Cloud Storage Controller, available immediately through channel partners. Bluejet cached high-priority data locally while using WAN optimization technology. The 2 rack unit (3.5-in-high) appliance acted as a local cache that uses a combination of DRAM, solid-state drives and hard disk drives. The multiple tiers of storage are governed by automated algorithms that allow Bluejet to place data on the appropriate media based on access patterns to achieve the best performance. The Bluejet appliance promised data compression ratios of 2:1 to 3:1, depending on the data type, and a data de-duplication ratio as high as 50:1 for backup. Overall, Cirtas raised US$32.5 million in private funding. In September 2010 Cirtas announced that it received US$10 million in A-round funding led by New Enterprise Associates, Lightspeed Venture Partners and Amazon.com.〔Computerworld, Start-up unveils SAN-to-cloud optimizer appliance, By Lucas Mearian Sept. 20, 2010 ()〕〔Cloud Computing Journal, Cloud Computing: Cirtas Systems Closes $10 Million Series A Funding Round, By Liz McMillan Sept. 20, 2010 ()〕〔Enterprise Storage Forum, Cirtas Launches Cloud Storage Controller, By Kevin Komiega Sept. 20, 2010 ()〕〔VentureBeat, Cirtas raises $10M and soars into cloud storage, By Dean Takahashi Sept. 20, 2010 ()〕 In January 2011 Cirtas announced that it had raised US$22.5 million in B-round funding, led by Shasta Ventures and Bessemer Venture Partners.〔Cirtas Systems Nets $22.5 Million in Series B Funding for Bluejet Cloud Storage Controller, Jan. 25, 2011 ()〕 In 2010 Cirtas was named a Red Herring Top 100 North American Company for its innovative approach to make cloud storage work like traditional on-site storage arrays.〔Cirtas Systems Named One of Red Herring's Top 100 - Mark of Distinction, Identifying Innovative New Companies, By Salvatore Genovese Jun. 29, 2010 ()〕 In 2011 Red Herring further awarded Cirtas the 2010 Global 100 award, recognizing the hundred most promising private companies in the world.〔(Cirtas Systems Wins Red Herring Global 100 Award, Jan. 28, 2011 )〕 According to Arun Taneja of Taneja Group, when tested in enterprises at large scale the Bluejet controllers failed to bring the needed performance. In April 2011, Cirtas pulled out of the market, laid off most of its staff, and the venture capital companies funding Cirtas rescinded their investment in the company.〔(Cirtas Systems Implodes, VC Pulls Out; What’s Next? )〕 ==See also== *Cloud computing *Cloud storage *Cloud storage gateway 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「Cirtas」の詳細全文を読む スポンサード リンク
