Navigating the road to flatter, converged data center networks
This article is part of the Network Evolution issue of November 2010 Vol. 1, No. 1
When it comes to building converged data center networks, network managers have lots of new choices in architecture and approach. In this feature, network managers discuss options for flat networks, integrated storage and networking for the private cloud. Byron DeLoach, director of architecture for managed services provider Terenine, is undergoing a process that network architects haven’t had to take seriously in a long time: thorough, comparative research on networking vendors and their differing approaches to building the LAN. That’s because for the first time in years, vendors are promising a revolution in how enterprises will design and build their networks in order to support server virtualization and private cloud computing. This revolution, they say, will include technology to consolidate data center and storage infrastructure using data center bridging and Fibre Channel over Ethernet (FCoE), creating converged data center networks. And it includes the move toward flatter data center networks by reducing the number of ...

ATA over Ethernet is pitched as a solution for converged data center networks, but ATAoE has a host of technology shortcomings, including a lack of packet loss recovery and shaky security, according to Fast Packet blogger Ivan Pepelnjak. So why bother?
IT professionals explore the process of building converged data center networks based on expectations of vendors’ promises, as well as their reservations, the benefits and technicalities of this technology.
