The US Federal Trade Commission (FTC) has cleared the acquisition of McData by Brocade.

The decision, following an antitrust review, removes the last regulatory hurdle to the deal.

Brocade, a maker of storage area network switches, made the $713 million stock offer for McData in August 2006. Both are rivals to industry giant Cisco.

The shareholders of Brocade and McData will hold separate meetings tomorrow to affirm the acquisition, which the companies expect to complete within a week.

Brocade's former chief executive officer and founder, Greg Reyes, left the company in 2005. He faces trial, along with other former Brocade executives, in San Francisco on charges related to backdating of stock option grants.
