Cisco at the show also unveiled plans to acquire Nuova Systems, the company it teamed with to develop the Nexus switch line. Cisco has already invested $70 million to acquire an 80-percent share of the company and now plans to purchase the remaining 20 percent in a deal expected to close by July. Soni Jiandani, vice president of marketing at Nuova, said the dropping prices of 10-Gigabit Ethernet technology will help drive consolidation in the data center. Jiandani, like several of Nuova's top executives, is a former Cisco employee.
