Understanding Flat Networks

A flat network or fabric provides more paths through the network and can maximize bandwidth and better support a highly virtualized data center. We'll look at standards-based approaches to designing a flat network, including TRILL and SPB, as well as proprietary implementations. We'll also discuss the implications of moving to a flat network and provide guidance to help you decide if this approach is right for your data center.

3 Paths To Network Convergence

Separate data and storage networks might have been necessary when Fast Ethernet was pitted against speedy, special-purpose Fibre Channel, but Ethernet's evolution has obviated most of the performance differences. We'll examine the trends behind network convergence, share exclusive research, and outline three deployment scenarios for those who want to merge data and storage networks.

Long-Distance LAN

Plan Now for the Hyperconverged Enterprise Network

In this Gartner report, industry analysts explain why changes in the business and application environment will result in up to 80% of end-user traffic moving to the WAN by 2014. This is a significant change to the old rule of thumb that 80% of traffic will stay within the enterprise LAN, and it means that network design is facing radical new requirements for network connectivity and performance. Find out how enterprises can modernize their network planning processes across IT groups to ensure they continue to meet business and end-user needs.
