“The wireless service and equipment providers chose the NEXUS product lines for their labs due to the integration of multiple functions—splitting, combining, attenuation and signal sensing—in a compact chassis that allows them to quickly emulate many different network configurations to rapidly test and debug their network equipment, software and system configurations,” says David Chan, Quintech Electronics’ vice president of sales and marketing. “Regression tests are completed faster and with greater quantity in the time allotted, and they are able to successfully launch new network equipment and applications on time and with less first release issues.”
What can I say, Nexus product line is Cisco’s main switch for datacenter environment and features like vPC are essential for it. What however I really miss on Nexus is the virtualization technology like HP IRF (which is actually much more powerful then vPC). Something like the what is available on Catalyst 6500 called VSS that makes two physical devices to become one logical devices similarly like stacking on normal switches (actually even here is HP IRF more powerful as it doesn’t have a limit of only 2 devices and for the actual stacking HP use classical ethernet/optical 10Gbps SFP ports and not proprietary cables, this enables creating Geo-Clusters of virtual switches across two data-centers via DWDM).
