HP 3PAR

3PAR Inc. was a manufacturer of systems and software for data storage and information management headquartered in Fremont, California, USA. 3PAR produced computer data storage products, including hardware disk arrays and storage management software. It became a wholly owned subsidiary of Hewlett Packard Enterprise after an acquisition in 2010.

3PAR was founded in mid-1998 or 1999, originally called 3PARdata. The founders included Jeffrey Price and Ashok Singhal, the P and A in the company's name. The R stands for a third partner, Robert Rogers, who left the company in 2001. David Scott became president and CEO in January 2001.

3PAR first shipped the InServ storage server in September 2002. 3PAR's primary competitors in the enterprise storage market are Dell EMC, Pure Storage, NetApp, Hitachi Data Systems and IBM. 3PAR called itself a pioneer of thin provisioning, a mechanism to improve the utilization efficiency of storage capacity deployment. 3PAR first announced this capability in June 2002 and shipped it to customers in 2003.

An investment round of almost $33 million was disclosed in February 2004. Investors included Mayfield Fund, Menlo Ventures and Worldview Technology Partners. In September 2007, 3PAR opened a second research and development office in Belfast, Northern Ireland. The company completed an initial public offering in November 2007 and was initially listed on the NYSE Arca exchange under the symbol PAR. In the same month, 3PAR introduced Virtual Domains, which allow for secure application data isolation on a consolidated multi-tenant storage platform. In December 2008, 3PAR moved to the NYSE Big Board. One year later, 3PAR opened an Indian subsidiary in Bangalore focused on providing logistical and administrative support for its Global Services and Support operations. In March 2010, the company introduced 3PAR Adaptive Optimization, the industry's first implementation of autonomic storage tiering for cost optimization in high-end storage systems, targeted at enterprises and service providers. In April 2010, the company was recognized by Forbes magazine as the fourth fastest growing technology company in its Tech25 list.
