After giving remedies to aid rival Marvell Technology, U.S. chipmaker Broadcom received EU antitrust permission on Wednesday for its $61 billion proposed takeover of cloud computing company VMware.

The largest-ever deal for Broadcom will help the chip manufacturer expand into corporate software.

The European Commission stated, confirming a Reuters report from last month, that Broadcom granted Marvell and other competitors interoperability promises relating to its Fibre Channel Host-Bus Adapters, a class of storage adapters.

According to the EU competition enforcer, Marvell and other competitors will have “guaranteed access to the interoperability Application Programming Interfaces as well as to the materials, tools, and technical support necessary for the development and certification of third-party FC HBAs.”

An irrevocable open source licence will ensure that Marvell and other competitors have unrestricted access to the source code for all of Broadcom’s FC HBA drivers, both present and future.

“The commitments offered by Broadcom will enable its only rival Marvell, to continue competing on equal footing and ensure a similar protection for any future entrants,” EU antitrust chief Margrethe Vestager said in a statement.

The deal is also being investigated by the UK competition authority and the US Federal Trade Commission.

“We continue to make progress with our various regulatory filings around the world, having received legal merger clearance in Australia, Brazil, Canada, the European Union, South Africa, and Taiwan, and foreign investment control clearance in all necessary jurisdictions,” Broadcom said in a statement.
