US data center firm Flexential is expanding again outside Portland, Oregon.

The GI Partners-backed firm this week announced the acquisition of a land parcel in Hillsboro, Oregon, that will be home to its sixth data center in the city.

Located across from Flexential's Hillsboro 1 data center at 3935 Northeast Aloclek Place, the site will host Hillsboro 6, a 350,000-square-foot (32,516 sqm), two-story data center expected to support 27MW of capacity. Timelines for development weren’t shared.

"Hillsboro has become a smart alternative to Silicon Valley for customers seeking the performance, flexibility, and cost structure they can't find elsewhere — especially those with strong ties across the Pacific," said Ryan Mallory, president and COO of Flexential. "This project reflects our belief in focused, right-sized development that enables customer growth without chasing unnecessary scale, and it furthers our commitment to delivering reliable solutions while introducing much-needed capacity in a highly coveted area."

Flexential operates four data centers in Hillsboro, with Hillsboro 5 — a 358,000 sq ft (33,295 sqm), 36MW facility — under construction and expected to come online next year. The company says the five sites total 1.18 million sq ft (109,625 sqm) and 113MW of capacity, according to its website.

The company noted Hillsboro posted a vacancy rate of 0.2 percent in the first half of the year. During that time, Hillsboro saw some 48MW of new capacity delivered and absorbed 48.4MW, equivalent to roughly 10 percent of its total inventory.

GI formed Flexential in 2017 after merging Peak 10 and ViaWest. GI acquired Peak 10 back in 2014. Morgan Stanley is also an investor. The company operates 40 data centers across 18 US markets and has more than 330MW of built and under-development capacity. It has projects in development across Parker, Colorado; Atlanta, Georgia; and Hillsboro, Oregon.
