HPE 3PAR
Enterprise data-storage systems and software brand originating with 3PAR Inc. and now owned by Hewlett Packard Enterprise.
Last updated August 22, 2026
Overview
HPE 3PAR is an enterprise storage brand whose technology originated with 3PAR Inc., a California company established in the late 1990s to develop high-end computer storage systems and storage-management software. The company was originally known as 3PARdata, a name associated with founders Jeffrey Price, Ashok Singhal, and Robert Rogers. The “3PAR” identity reflected the company’s three original partners, although Rogers left the business in 2001. David Scott became president and chief executive officer in January 2001 and led the company through its transition from an early-stage storage developer into a public enterprise-technology supplier. 3PAR’s central proposition was to make storage infrastructure more efficient, flexible, and suitable for shared or utility-style computing environments. Its products combined disk-array hardware with software for provisioning, virtualization, management, replication, and workload placement. The company was especially associated with thin provisioning, which allows storage capacity to be allocated logically as needed rather than physically reserving the full amount in advance. 3PAR announced this capability in 2002 and began shipping it to customers in 2003. The approach was well suited to data centers operated by service providers, enterprises consolidating applications, and emerging cloud-computing environments in which storage had to support multiple tenants and changing workloads. The company’s first InServ storage server shipped in September 2002. By the middle of the 2000s, the InServ family served both high-end and modular-array segments. Models such as the T400 and T800 were positioned against large monolithic systems, while the F200 and F400 addressed modular enterprise storage deployments. 3PAR described its broader architecture as “utility storage”: a shared, virtualized storage foundation intended to support infrastructure-as-a-service, software-as-a-service, hosting, and internal IT service-bureau models. Its product differentiation included a custom application-specific integrated circuit architecture, automated provisioning, multi-tenant isolation, and software-directed management of storage resources. 3PAR raised almost $33 million in disclosed financing in 2004 from investors including Mayfield Fund, Menlo Ventures, and Worldview Technology Partners. It expanded its engineering footprint with a research and development office in Belfast, Northern Ireland, in 2007 and established an Indian subsidiary in Bangalore in 2009 for logistical, administrative, global-services, and support activities. The company went public in November 2007 under the symbol PAR and transferred from NYSE Arca to the New York Stock Exchange’s main board in December 2008. In 2010 it introduced Adaptive Optimization, an automated storage-tiering technology intended to place data on appropriate performance tiers while controlling infrastructure cost. 3PAR became the subject of a highly competitive acquisition contest in 2010. Dell first announced a proposed acquisition in August, after which Hewlett-Packard made a higher offer. Repeated counterbids increased the transaction value substantially, reflecting the strategic importance of 3PAR’s technology for virtualization and cloud-oriented storage. HP completed the acquisition on September 27, 2010, for approximately $2.35 billion. 3PAR subsequently operated within HP’s enterprise-storage portfolio. When HP separated its enterprise businesses in 2015, the brand and related assets became part of Hewlett Packard Enterprise. Under HPE, the 3PAR portfolio included the 8000, 9000, and 20000 series, covering midrange through high-end enterprise deployments and offering flash and hybrid configurations. The platforms shared the 3PAR operating-system environment and an ASIC-based architecture supporting functions such as thin provisioning, compression, deduplication, and parity calculations. HPE later positioned 3PAR within its broader storage business alon…
History
3PAR was founded in California in the late 1990s as 3PARdata by Jeffrey Price, Ashok Singhal, and Robert Rogers. Rogers departed in 2001, and David Scott became president and chief executive officer in January of that year. The company focused on enterprise storage hardware and software at a time when organizations were moving from dedicated application silos toward virtualized and shared data-center infrastructure. Its first major product was the InServ storage server, shipped in September 2002. 3PAR promoted a concept it called utility storage, in which a common storage platform could serve multiple customers, applications, or organizational units while allowing capacity and performance to be managed dynamically. This model addressed the requirements of hosting providers, cloud services, and enterprises building internal shared-service environments. Thin provisioning became one of the company’s most distinctive technologies. Announced in 2002 and shipped commercially in 2003, it enabled logical capacity to be presented without immediately consuming equivalent physical capacity, improving utilization and simplifying expansion. During the 2000s, 3PAR broadened its portfolio across high-end and modular storage. The InServ T400 and T800 were aimed at large enterprise installations, while the F200 and F400 addressed modular-array deployments. The product architecture combined storage controllers, proprietary ASIC technology, and management software. Additional capabilities included virtualization, secure isolation of application data, replication, automated provisioning, and support for multi-tenant environments. 3PAR disclosed an investment round of nearly $33 million in February 2004. Its international engineering and support footprint expanded with a Belfast research and development office in September 2007 and an Indian subsidiary in Bangalore in 2009. The company completed an initial public offering in November 2007 under the symbol PAR and moved its listing to the New York Stock Exchange’s main board in December 2008. In November 2007 it also introduced Virtual Domains, designed to isolate data and administration within a consolidated storage platform. In March 2010, 3PAR announced Adaptive Optimization, an automated storage-tiering system intended to balance application performance and storage cost. The company attracted acquisition interest as demand grew for storage supporting virtualization and cloud computing. Dell announced a proposed acquisition on August 16, 2010. HP entered the contest with a larger offer on August 23. After several rounds of bids, HP offered approximately $2.4 billion, or $33 per share, while Dell’s offer reached $32 per share. The original Dell agreement was terminated, with Dell receiving a break-up fee reported at $72 million. HP completed the acquisition on September 27, 2010, for approximately $2.35 billion. 3PAR continued as a storage technology and product identity within HP. In 2015, HP separated its enterprise assets into Hewlett Packard Enterprise, and 3PAR became part of HPE. The later portfolio included the 8000, 9000, and 20000 series. These systems covered midrange, intermediate, and high-end requirements, with flash and hybrid configurations. The platforms shared the 3PAR operating-system foundation and ASIC-based design, supporting thin provisioning, compression, deduplication, and parity processing. HPE subsequently developed a wider storage portfolio, but 3PAR remains associated with the company’s enterprise-array heritage and its early emphasis on efficient, automated, multi-tenant storage.
