Virtual cluster switching: Finding management in a flat network
This article is part of the Network Evolution issue of November 2010 Vol. 1, No. 1
Networking managers are taking varied paths toward architecting high performance networks. For some, the answer lies in a flat Layer 2 design, which can be difficult to manage. That's where virtual cluster switching comes into play. Using virtual chassis technology, networking teams can manage multiple switches as one. The UCLA Laboratory of Neuro Imaging (LONI) is the very definition of a high-performance computing data center. The lab maps the human brain and continually adds scanned data to the nearly petabyte-sized imaging database, which is constantly accessed by about 1,000 researchers trying to understand and cure diseases like Alzheimer’s and schizophrenia. Hundreds of researchers are active at any given time, working with datasets from 20 MB to hundreds of gigabytes. ike many enterprises that rely on high-performance computing, LONI implemented a non-blocked, flat Layer-2 network with all the racks of servers directly connected. But David Hasson, LONI director of information technology, found that he needed more ...

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.
Using virtual cluster switching, the UCLA Laboratory of Neuro Imaging manages dozens of switches as one switch in a flat Layer 2 network for high-performance computing.
