Executive Summary

For data center storage networks, the most common technologies in use today are Ethernet, Fibre Channel, and, to a lesser extent, Infiniband. Ethernet is the network technology of choice for the Internet and other user networks, and is rapidly gaining in popularity as a storage network. Fibre Channel is the dominant technology for storage networks, trailed by Ethernet, then Infiniband. It is common for data centers to include multiple single-purpose networks for data storage, with each storage network requiring separate capital and operational budgets. In good economic times, the capital and operating cost required to maintain separate networks may be justified to support optimizing the environment around other priorities, such as higher performance or additional support for new business applications.
