Chinese authorities are reviewing the use of Broadcom switches in state controlled data centres as the country moves to strengthen domestic technology and reduce dependence on foreign suppliers, according to a report.

The State owned Assets Supervision and Administration Commission has reportedly spent recent weeks checking how widely Broadcom networking equipment is being used across data centres operated by state controlled entities.

The review reportedly found that Broadcom switches may make up as much as 90 percent of the equipment currently installed in some facilities. Based on the initial findings, authorities could issue informal guidance encouraging state run data centres to reduce their reliance on the company’s products.

The move would fit into China’s wider effort to increase the use of domestically developed chips and artificial intelligence technology across the public sector. Broadcom, Nvidia and Huawei are among the companies supplying high end networking switches in the Chinese market.

Nvidia products have already been restricted from state backed data centres, while Broadcom equipment continues to have a significant presence. The reported findings have not been independently verified, and Broadcom and the relevant Chinese authorities were not immediately available for comment.
