The company is one of the largest producers of high-performance and high-efficiency servers,[2] while also providing server management software, and storage systems for various markets, including enterprise data centers, cloud computing, artificial intelligence, 5G, and edge computing.[3][4][5][6][7][8]
In 1993, Supermicro began as a five-person business operation run by Charles Liang, a Taiwanese-American, alongside his wife and company treasurer, Chiu-Chu Liu, known as Sara. Prior to founding Supermicro, Liang earned a B.S. in electrical engineering from the National Taiwan University of Science and Technology and an M.S. in electrical engineering from the University of Texas at Arlington. Liang holds several patents for server technology and was previously the president and chief design engineer of Micro Center Computer, a motherboard design and manufacturing company, from July 1991 to August 1993.[9] Liang stated that the company was able to turn a profit after six months of operation.
The same year it was founded, Supermicro established its first European partnership with Boston Limited, a UK-based IT solutions provider, which launched Supermicro products into the UK and European markets. The continued collaboration has seen several Supermicro technologies introduced to Europe, including the P5EXTRA in the 1990s, the 1U Twin in 2006, and innovations such as the Supercool 1U Twin in 2007[10] and high-performance GPU computing systems in 2009.[11]
In 1996, the company opened a manufacturing subsidiary, Ablecom, in Taiwan, which is run by Charles's brothers, Steve Liang and Bill Liang. Charles Liang and his wife own close to 31 percent of Ablecom, while Steve Liang and other members of the family own close to 50 percent.[3]
