Isilon is a scale out network-attached storage platform offered by EMC Corporation for high-volume storage, backup and archiving of unstructured data. It provides a cluster-based storage array based on industry standard hardware, and is scalable to 50 petabytes in a single filesystem using its FreeBSD-derived OneFS file system. An Isilon clustered storage system is composed of three or more nodes. Each node is a self-contained, rack-mountable device that contains industry standard hardware, including disk drives, CPU, memory and network interfaces, and is integrated with proprietary operating system software called OneFS (based on FreeBSD), which unifies a cluster of nodes into a single shared resource. Current Isilon hardware platforms include the S-Series nodes, which support high-performance, process-intensive, high-transaction applications; the X-Series nodes, which support high-throughput and high-concurrency application needs; the NL-Series nearline storage nodes, which support archiving, disaster recovery and disk-to-disk backup needs; and the HD-Series nodes, which support large-scale, high-density deep archive storage needs, as well as disaster recovery and, when combined with other nodes, an enterprise data lake foundation. Isilon also offers A-Series Accelerator nodes, which scale cluster performance and data backup processes. == History == Isilon Systems was a computer hardware and software company founded in 2001 by Sujal Patel. It was headquartered in Seattle, Washington. It sold clustered file system hardware and software for digital content and other unstructured data to a variety of industries. Isilon Systems designed and developed its clustered storage systems specifically to address the needs of storing, managing and accessing digital content and other unstructured data. Isilon Systems received $8.4 million in Series A venture funding in 2001, $15 million in Series B funding in 2002, and $20 million in funding in 2005. Investors in Isilon Systems have included Atlas Ventures, Focus Ventures, GCV Capital, Lehman Brothers, Madrona Venture Group and Sequoia Capital. Isilon Systems became a publicly traded company on December 16, 2006. By this time, Isilon was selling its products indirectly through a channel partner program that included over 100 resellers and distributors, as well as directly through a field sales force. Its customers included NBC Universal, Cedars-Sinai, Kelman Technologies, and Kodak, among others. Poor initial performance of the new public company led to management changes in 2007 that brought back founder Sujal Patel as CEO. In 2008, details emerged around an internal audit of Isilon System’s financials that led to a restatement of earnings. Just before the company would have announced four profitable quarters in a row – the first in profitable year in the company’s history – Isilon Systems was acquired by EMC Corporation in November 2010 for $2.25 billion. EMC said that with its acquisition of Isilon, it would be better able to provide storage infrastructure for private and public cloud environments, with a focus on so-called big data, like gene sequencing, online streaming, and oil and natural gas seismic studies. At the time of acquisition, the list of Isilon’s clients had grown to include Sony, XM Radio, LexisNexis, Facebook, MySpace, Adobe, and several major movie studios and TV networks. On November 10, 2015, EMC announced an expansion of its Isilon NAS portfolio with a scaled-down, software storage system for remote locations, a cloud migration application and high-availability upgrades for Isilon OneFS. The two software additions, IsilonSD Edge and CloudPools, will be available alongside the new version of OneFS in 2016. They are part of the vendor's data lakes strategy for storing and managing unstructured data in large repositories. The new offerings will, according to one analyst, deliver a data lake-ready platform to enterprises with high-speed data analytics, and are aimed at three aspects of the Data Lake, the edge, the core, and the cloud. 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「EMC Isilon」の詳細全文を読む スポンサード リンク
