Today's data centers are increasingly filled with dense rack-mount and blade servers that host powerful multicore processors. The rapid increase in in-rack computing density and the increasing use of virtualization software combine to accelerate the demand for 10 Gigabit Ethernet and consolidated I/O: applications for which the Cisco Nexus® 5000 Series Switches are an excellent match. With low latency and choice of front-to-back or back-to-front cooling, copper or fiber access ports, and rear-facing data ports, the Cisco Nexus 5000 Series is designed for a broad range of physical, virtual, storage access, and high-performance computing environments, thus giving customers the flexibility to meet and scale their data center requirements in a gradual manner and at a pace that aligns with their business objectives.
