Analyst(s): David Passmore

Summary

Over the past few years, there have been relatively few changes to enterprise-class Ethernet switches. But now, with 10GBase-T driving down the cost of 10 Gigabit Ethernet (10GbE) local area networks (LANs)--combined with growing use of Ethernet for storage networking as a substitute for Fibre Channel and a need for greater bandwidth/availability and lower power consumption--vendors such as Cisco Systems and Juniper Networks have recently introduced entirely new families of Ethernet switches. In this report, Research Director Dave Passmore examines the latest products and discusses what's really new about next-generation switches.
