An inside tour of Lenovo’s North Carolina AI server manufacturing line expansion — Chinese firm expanding US-native production to meet exploding demand

There are currently seven assembly lines, residing in a space roughly double the size of the kitting area (53,000 square feet). Lenovo has the capacity to produce 1,400 server nodes per day across 28 assembly stations (one server is produced every 60 seconds).

At full tilt, Lenovo says that it will have 1,000 operators running three shifts. However, there are currently around 380. Employees get roughly 1,000 hours of training, and they rotate throughout different phases of the building process to hone their skills.

After touring the kitting and assembly lines, we moved into the testing areas, where L10 testing takes place. There are 10 thermally controlled testing pods, with 16 test racks per pod. The room is chilled using massive Computer Room Air Handlers (CRAH), each with 1 MW of cooling capacity.

In addition, there are 30 Vertiv Liebert XDU direct liquid cooling units (expandable to 50), each with a capacity of up to 300 kW, to aid with testing finished packages for customers. Lenovo explained that Nvidia GB300 racks consume 140 kW, while Vera Rubin will consume 230 kW at peak load. For comparison, the average U.S. household consumes between 1 and 1.5 kW per day. That's a lot of power coming from a rack measuring 18 inches across and seven feet tall. Lenovo’s first taste of Vera Rubin is said to be making its way to the Whitsett facility by the end of August.

We also toured where the massive freshwater pipes enter the building to fuel the cooling operations, along with the utility room, where the impressive overhead electrical conduits feed power into the site from a nearby substation. Working with Duke Energy, Lenovo was able to go from temporary power at the site to full power within 7 months.
