Who Owns Raritan?

Raritan was established in 1985 by Ching-I Hsu and his wife, who started a business reselling PC components from their home. The company soon shifted from reselling to manufacturing PCs. To make PC manufacturing more efficient, Hsu developed the first KVM switch, a hardware device that allows a single keyboard, video monitor, and mouse to control multiple computers. This invention became Raritan's defining product and propelled the company from a small operation into an international business.

Through the 1990s and 2000s, Raritan expanded its KVM switch product line and added intelligent power distribution units (PDUs) and environmental sensors to its portfolio. The company built a customer base of Fortune 500 technology companies and government agencies, with products deployed in over 50,000 locations across 76 countries. Raritan also developed Data Center Infrastructure Management (DCIM) software to help IT administrators monitor and manage data center resources.

A major product milestone came with the Dominion KX series of KVM-over-IP switches, which allow remote BIOS-level access to servers over a network. The Dominion KX III, Raritan's flagship enterprise KVM-over-IP switch, supports 1, 2, 4, or 8 concurrent users managing 8, 16, 32, or 64 servers from a single appliance. It offers DVI, HDMI, DisplayPort, USB-C, and VGA video support, virtual media, smart card/CAC authentication, and mobile access. The Dominion KX III targets enterprise data centers, broadcast facilities, and government installations requiring secure remote server management.

In June 2015, Legrand, North America announced a definitive agreement to acquire Raritan. The deal was structured to include Raritan's intelligent power and KVM businesses, while the DCIM software unit was separated into Sunbird Software, a new company chaired by Ching-I Hsu. The acquisition closed on September 28, 2015. Raritan became part of Legrand's data center infrastructure division, operating as an independent business within Legrand North America.

Following the acquisition, Raritan continued developing its KVM and PDU product lines under Legrand ownership. The company introduced the Dominion KX III G2, a next-generation KVM platform designed for faster outage recovery, secure remote hardware access, and automation at scale. Raritan also expanded its intelligent PDU offerings with features for real-time energy monitoring and environmental sensing in data center racks.

Raritan has been recognized by the U.S. Environmental Protection Agency for its contributions to the agency's data center initiative. The company is an active member of The Green Grid, Climate Savers Computing Initiative, and LEED associations. These memberships reflect Raritan's focus on energy-efficient data center infrastructure, which aligns with Legrand's broader sustainability strategy.

As of 2026, Raritan employs approximately 104 people across 10 countries, with offices in the United States, Taiwan, Germany, China, and Japan. The brand continues to serve data center customers globally through Legrand's distribution network while maintaining its own product development and engineering teams.
