From a technology product perspective, we saw an improved demand environment for capital expenditures and growth across each of our major product categories. In fiscal 2010, switching revenue was up approximately 12% from a year ago, due in part to the ongoing success of our Nexus family of next-generation data center switches, which has attained an annualized revenue run rate of over $2 billion as of the fourth quarter of fiscal 2010. Cisco’s Unified Computing Systems (UCS) offering, which also addresses the transition occurring in the data center, witnessed outstanding customer acceptance driven by the move to data center virtualization and cloud computing. In less than one year, the total number of unique customers for Cisco UCS has reached over 1,700, nearly doubling in the last quarter of fiscal 2010. As networking, servers, storage and software come together, we believe we have uniquely positioned Cisco to lead with an architectural approach that is unmatched in the industry.
Routing revenue was up approximately 4% from a year ago. Following the remarkable success of our CRS-1 high end router, Cisco unveiled the CRS-3, which we believe will serve as the foundation for the next-generation Internet and the astonishing growth of video transmission, mobile devices, and new online services throughout the next decade. We also launched next-generation edge and branch routing systems in fiscal 2010, and received very positive customer feedback.
Our collaboration technologies, including Unified Communications and Cisco TelePresence, each saw strong revenue growth. Other noteworthy product revenue growth included the success of our Flip video products.
Cisco completed several acquisitions in fiscal 2010 that underscored our commitment to our "build, buy, and partner" strategy. The acquisition of Starent Networks Corp., a provider of IP-based mobile infrastructure for carriers, helped Cisco’s portfolio of products enable multimedia experiences for mobile subscribers. We likewise were pleased to welcome Tandberg ASA, a leader in video communications. With this acquisition, Cisco expects to be able to combine video innovations with multi vendor interoperability capabilities. Other acquisitions by Cisco in fiscal 2010 included ScanSafe, Inc., a provider of hosted web security, and CoreOptics Inc., a designer of digital signal processing solutions.
