UC San Diego Computer Scientists Propose New Data Center Architecture Based on Commodity Network Elements

University of California, San Diego (UCSD) computer scientists have proposed a new way of building data centers that could lower costs and provide more computing capability for end users. UCSD professor Amin Vahdat’s paper, “A Scalable Commodity Data Center Network Architecture,” was presented at the annual ACM SIGCOMM meeting in Seattle. “Large companies are putting together server farms of tens of thousands of computers–even approaching 100-thousand–and the big challenge is to interconnect all these computers so that they can talk to each other as quickly as possible, without incurring significant costs,” Vahdat says. “We are proposing a new topology for Ethernet data center connectivity.” The research addresses problems inherent in modern data center networks with large-scale computation or storage requirements. Vahdat say the work addresses the problem of data center network connectivity in a world where consolidation is increasingly common in data centers. The UCSD researchers propose creating a data center that has scalable interconnection bandwidth, making it possible for an arbitrary host in the data center to communicate with any other host in the network at the full bandwidth of its local network interface. The approach requires no modifications to end-host network interfaces, operating systems, or applications, and is backward compatible with Ethernet, IP, and TCP.
