9. Brocade Communications
Brocade secured the No. 9 spot on NPD's list, with its switches representing 1.2 percent of the total units shipped last year.
Brocade in 2013 made several updates to its switching line, many of which were designed to fuel its broader push in the SDN and network virtualization markets. In September, Brocade expanded its VDX line of switches with the launch of its VDX 6740 series. Consisting of two 48-port switches, the new VDX 6740 line utilizes Brocade's VCS Fabric technology to help users build out Ethernet fabrics and cloud-optimized networks.
In another push toward SDN, Brocade earlier this year announced OpenFlow 1.3 support across its entire IP switching and routing portfolio.
