  • 40 and 100 Gigabit Ethernet ratification doesn't mean immediate uptake

    40 and 100 Gigabit Ethernet ratification means that vendors can roll out standardized 40 and 100 GbE switching products with enormous speed, but users are likely to hold off until prices come down and the need for performance is greater. 

  • Will TRILL replace spanning tree protocol in data center networks?

    The Transparent Interconnection of Lots of Links (TRILL) protocol is a pending IETF standard that could eliminate spanning tree protocol from standard data center network design. Vendors like Brocade are already staking their future on it. 

  • Data center networks and server virtualization: Who has a silver bullet?

    Server virtualization has forced network vendors to reinvent the data center network. Everyone has his own vision of how to deliver a network that is optimized for virtual data centers. Enterprises should think twice about just going with their incum... 

  • Interop panel discusses future of data center network architecture

    Data center network architecture is heading for a reckoning, according to vendors at Interop. During a panel session dubbed "Why the Network Must Fundamentally Change," vendors like Cisco, Juniper and HP predicted a data center with a flat Layer 2 ne... 

  • FCoE data center: Can data and storage network convergence go too far?

    The FCoE data center offers enterprises the opportunity to converge data and storage traffic on a single network infrastructure. Most experts see data center network convergence as an opportunity to reduce cost and complexity within servers and racks... 

  • Cisco Unified Computing pushes to support every fabric

    Cisco released new Cisco Unified Computing fabric extenders that will enable Nexus 5000 switches to support multiple types of fabrics ranging from Fibre Channel over Ethernet Infiniband (FCoE) to iSCSI and Infiniband. 

  • 10 GbE switches: How important is the race for highest-density core?

    Port density in 10 Gigabit Ethernet switches is a horserace, and Force10 is currently in the lead with its new E-Series ExaScale line cards. But how many network engineers really need a network core switch with that much firepower? Virtualization, cl... 

  • Cisco UCS testing shows throughput constraints, one lab says

    Cisco UCS testing results from the Tolly Group indicate that throughput is much lower than Cisco claims. Tolly claims Cisco unified computing architecture relies on oversubscribed blade servers and clumsy external switches. 

  • Half of enterprises to have 10 GbE switches in core by 2012

    Virtualization and data center consolidation lower costs and improve efficiency but require more powerful networks, which is why one organization in two is expected to deploy 10 Gigabit Ethernet (GbE) switches in the core by 2012, according to a rece... 

  • Data center networks in 2010: Two-tier networks arrive

    SearchNetworking.com asked Gartner Research VP Joe Skorupa to predict what 2010 has in store for data center networks. He sees a price war driven by the HP-3Com merger, the rise of two-tiered architecture, and more 10 Gigabit Ethernet adoption.
