Notes
The Nexus 7000 and Cisco Catalyst 6500 and Catalyst 4500 Series 
modular switches provide customers with an intelligent platform for 
deploying numerous, concurrent intelligent services without degrading 
the overall performance of the switch. With a broad selection of line 
cards and power supplies and their highly versatile architecture, modular 
switches deliver the highest levels of port density and flexibility to meet 
the requirements of campus and data center networks.
These extensive product portfolios allow customers to build an 
infrastructure that can be scaled cost-effectively and that helps  
increase energy, budget, and resource efficiency. Customers can 
simplify the transition to 10, 40, and 100 Gigabit Ethernet, handle 
architectural changes such as virtualization, Web 2.0 applications,  
and cloud computing as well as support converged applications in a  
secure architecture. 
To minimize costly user downtime, modular switches are optimized for 
operational continuity in order to create an environment where system 
availability is assumed and maintenance downtime windows are rare or 
nonexistent. Critical redundant hardware and software features deliver 
the highest resiliency for all places in the network. Modular switches 
also provide the highest levels of investment protection. New features, 
innovations and functionality can be easily added with cost effective 
incremental upgrades to supervisors, linecards and fabric modules 
(Nexus 7000). This approach not only protects a majority of the initial 
investment but enhances the investment with new functionality while 
mitigating the need for disruptive fork-lift upgrades.
