A former IBM rsearch campus in San Jose, California, is being acquired by a data center firm.

As reported by Mercury News, new data center developer Blackstart Digital has acquired the former IBM Almaden Research Center in San Jose. Terms of the deal have not been shared.

The company is buying the campus at 650 Harry Road in a deal that could close before the end of the year. Blackstart has reportedly already filed for an environmental review for renovations.

“For decades, researchers on this hilltop did work that helped make Silicon Valley what it is today,” Blackstart Digital told the publication. “Our first goal is simply to put this campus back to work in a way that honors its legacy.”

The campus totals seven buildings over 35 acres, totaling more than 500,000 sq ft (46,450 sqm). The site already hosts some data center space and is served by a 25MW substation that Blackstart is aiming to expand.

There is more than 500 acres of open space Blackstart said it plans to leave undeveloped.

In August, the San Jose City Council voted to rezone the campus as an “industrial park zoning district,” potentially paving the way for data center development.

City staff had disclosed that multiple real estate executives have spoken with San Jose planners about potential development opportunities for the site. Sierra Club had been against the rezoning due to the potential for data center development.

Little information is available about Blackstart or its plans. The California-based company was co-founded last year by Chadwick Manning, who has previously led several renewable energy and power firms.

According to LinkedIn, other execs at the company include alumni from Digital Realty and Deutsche Telekom, as well as several other firms linked to Manning. Element Critical/Evocative founder and Foundation DC CEO Arman Khalili is listed as a partner.

IBM put the Almaden site on the market after deciding to relocate staff to its Silicon Valley Lab at 555 Bailey Road in San Jose last year.

Launched in 1986, innovations developed at the site include the first inkjet printer prototype, the first hard-disk drive, the relational database, and DVD and Blu-ray encryption. It was also the site where IBM’s TrueNorth brain-inspired neurosynaptic chip was developed.
