Overview
Silicon Graphics International Corporation, commonly known as SGI, was an American computer hardware and software company that operated as the successor to Rackable Systems and the corporate inheritor of much of Silicon Graphics, Inc.'s business. Although the SGI name became prominent in 2009, the operating company originated in 1999 as Rackable Systems, a manufacturer focused on rack-mounted servers and data-center infrastructure. Rackable went public in 2005 and developed a business serving organizations that needed dense, scalable computing equipment rather than conventional desktop workstations. The company's decisive transformation came during the financial collapse of the original Silicon Graphics, Inc. Rackable announced in April 2009 that it would acquire Silicon Graphics, Inc. from bankruptcy. The transaction was completed on May 11, 2009, for a final reported consideration of approximately $42.5 million. Rackable adopted SGI as its global corporate name and brand, and subsequently changed its NASDAQ ticker from RACK to SGI. The reconstituted company combined Rackable's x86 server and storage operations with the acquired SGI portfolio of high-performance computing systems, visualization products, software, professional services, and related technologies. SGI's post-2009 business was aimed primarily at technically demanding institutional customers. Its systems were used in scientific research, engineering, government, energy, manufacturing, media, and other environments requiring large-scale computation, high memory capacity, data-intensive analytics, visualization, or persistent storage. The portfolio included x86-based servers, high-performance computing platforms, shared-memory systems, clustered systems, storage appliances, archival storage, visualization technologies, and services for designing and operating specialized computing environments. The company retained and developed product families associated with SGI's technical heritage, including the UV and ICE lines, while also continuing server and storage products inherited from Rackable Systems. During the 2010s, SGI expanded selectively through acquisitions and asset purchases. In 2010 it acquired the assets and assumed a limited amount of liabilities of COPAN Systems, adding long-term, readily accessible data-archive products to its storage offering. In 2011 it acquired the outstanding shares of SGI Japan and announced the acquisition of OpenCFD, whose computational-fluid-dynamics software complemented the company's engineering and high-performance-computing activities. In 2013 SGI acquired FileTek, a company associated with data management and storage software. These moves reflected an effort to offer integrated computing, simulation, data-management, and storage capabilities rather than relying solely on hardware sales. The company experienced leadership changes during this period. Mark J. Barrenechea resigned as president and chief executive officer in late 2011 and later continued to serve on the board. Jorge Luis Titinger became president and chief executive officer in 2012. SGI remained a specialized supplier in a competitive market increasingly shaped by commodity x86 hardware, cloud computing, large technology vendors, and changing procurement patterns in scientific and enterprise computing. Hewlett Packard Enterprise announced in August 2016 that it would acquire SGI for $7.75 per share in cash, in a transaction valued at approximately $275 million net of cash and debt. The acquisition was completed on November 1, 2016. Following the transaction, SGI's technologies and business activities were absorbed into HPE's enterprise and high-performance-computing operations. The standalone SGI corporate identity was subsequently discontinued, although the SGI name and technical heritage continued to be associated with certain products, technologies, and historical systems.
History
Silicon Graphics International grew out of Rackable Systems, which was founded in 1999 to develop rack-mounted servers and related data-center hardware. Rackable pursued a model centered on scalable, space-efficient infrastructure for organizations operating large computing installations. The company became publicly traded in June 2005, when it offered 6.25 million shares at $12 per share. It later announced an agreement to acquire Terrascale Technologies in 2006, continuing its expansion in high-performance and data-center computing. The original Silicon Graphics, Inc., historically known for advanced workstations, graphics systems, visualization, and supercomputing, entered bankruptcy in 2009. Rackable announced on April 1, 2009, that it would acquire Silicon Graphics, Inc. for an initially reported $25 million. The transaction closed on May 11, 2009, with a final reported consideration of approximately $42.5 million. At closing, Rackable adopted Silicon Graphics International, or SGI, as its global name and brand. The company's NASDAQ ticker was changed from RACK to SGI the following week. The post-acquisition business combined two related but distinct portfolios. Rackable contributed x86-based servers and storage systems aimed at data-center deployment, while the acquired SGI operations supplied high-performance computing, large-scale shared-memory systems, visualization products, professional services, software, and established customer relationships in scientific and industrial markets. SGI expected most product lines to continue, although overlap between the businesses created a need for consolidation. SGI's principal customers included research institutions, government agencies, universities, engineering organizations, manufacturers, energy companies, and media or entertainment businesses with demanding computational and visualization requirements. Its products were intended for workloads such as scientific simulation, computational fluid dynamics, seismic analysis, technical visualization, large-scale analytics, and management of persistent data. The company maintained a position between commodity server vendors and highly specialized systems providers by combining standard x86 infrastructure with proprietary system architectures, software, and services. In 2010, SGI purchased the assets and assumed a limited amount of liabilities of COPAN Systems. COPAN specialized in storage archives designed to keep large data collections available for real-time access over long retention periods. SGI incorporated those products into its storage business. In 2011, SGI acquired all outstanding shares of SGI Japan, strengthening control of that regional operation, and announced the acquisition of OpenCFD Ltd., associated with computational-fluid-dynamics software. In 2013, it acquired FileTek, adding further data-management and storage expertise. Leadership changed during the company's independent period. Mark J. Barrenechea resigned as president and chief executive officer in December 2011, although he subsequently continued to serve on SGI's board. Jorge Luis Titinger was announced as his successor in February 2012. SGI continued to operate in a market affected by falling prices for standardized computing hardware, competition from major enterprise vendors, the emergence of cloud services, and the capital intensity of high-performance-computing procurement. The company also became associated with a 2015 report that an employee claimed engineering documentation for IRIS and MIPS hardware had been destroyed in 2010. The matter was significant primarily as a preservation issue involving the historical record of SGI technology; the available reference material does not establish a broader legal or regulatory finding. On August 11, 2016, Hewlett Packard Enterprise announced that it would acquire SGI for $7.75 per share in cash. The transaction was valued at approximately $275 million net of cash and debt. HPE completed the acquisition on November 1, 2016. SGI therefore ceased to operate as an independent public company, and its products, personnel, technologies, and customer activities were incorporated into HPE's enterprise and high-performance-computing organization. The standalone corporate brand subsequently faded, although SGI remains important in the history of technical computing and visualization.
