Cisco Modular Switches
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.
