Taiwan's Zettabyte, a GPU Infrastructure-as-a-Service provider, has introduced liquid cooling at a Chief Telecom data center in Taiwan.

Zettabyte this week announced the successful retrofit of Chief Telecoms’s legacy data center into a direct-to-chip liquid cooling-ready facility capable of hosting 100kW+ racks, which are Nvidia GB300 ready.

Though details on which facility was upgraded are sparse, the site was previously designed for 20kW racks. The upgrade was delivered in 45 days.

"This milestone showcases how Zettabyte's technology accelerates the transition from legacy to next-generation AI data centers," said Kenneth Tai, chairman of Zettabyte. "In just 45 days, we turned Chief's facility into a GB300-ready hub. This is a blueprint for how the world's data centers can adapt to the AI era—fast, efficiently, and sustainably."

"At Chief Telecom, we are committed to pioneering the future of AI services in Taiwan and beyond," added Johnny Liu, CEO of Chief Telecom. "Partnering with Zettabyte allowed us to transform our infrastructure at unprecedented speed, ensuring our customers can access the most advanced, power-dense AI platforms available today."

Zettabyte offers GPU cloud services, providing access to Nvidia Blackwell, H200, and H100 hardware. The firm has previously secured funding from Lam Capital.

In August 2024, Zettabyte was said to be working on an AI data center in Taiwan in partnership with Wistron Corporation. Details, including timelines, location, or facility specifications, weren’t shared. No updates on the data center have since been provided.

This pilot project marks the first milestone for Zettabyte Titan, the company's flagship initiative to “redefine next-generation AI infrastructure.”

Titan was launched last month alongside investment from private equity firm BRV Capital. The company said the initiative is designed to support the accelerating demands of intense workloads, and aims to accelerate Zettabyte's data center supply chain buildout in Taiwan.

Established in 1991, Chief Telecom is primarily a data center operator, with four data centers in Taipei, Taiwan’s capital. It is owned by Taiwan telecoms giant Chunghwa Telecom, and also operates cloud and networking services. The company runs the Taipei Internet eXchange (TPIX).

Chief launched its Liyuan 2 (LY2) facility in late 2024. The 20MW site totals 160,000 sq ft (14,864 sqm) of floorspace across seven floors and is expected to reach 80 percent occupied by the end of the year. The site reportedly offers 10-150kW per rack, supporting air and liquid cooling.
