Organizations everywhere recognize that changing application environments are creating new demands for the IT infrastructure that supports them. Application workloads are deployed across a mix of virtualized and nonvirtualized server and storage infrastructure requiring a network infrastructure that provides consistent connectivity security and visibility across a range of bare-metal virtualized and cloud computing environments:

• Application instances are created dynamically. As a result the provisioning modification and removal of application network connectivity needs to be dynamic as well.

• Business units demand accelerated application deployments. IT departments have to provide shared IT infrastructure to address time-to-market needs and to increase their return on investment (ROI).

• With organizations deploying a mix of custom open source and off-the-shelf commercial applications IT departments must manage both security and quality of service (QoS) for environments that support multitenancy.

• Applications have been transitioning over time to a less monolithic scale-out multinode model. IT infrastructure that supports this model must scale with the speed of business and support both 10 and 40 Gigabit Ethernet connectivity.

The Cisco Nexus® 9000 Series Switches include both modular and fixed-port switches that are designed to overcome these challenges with a flexible agile low-cost application-centric infrastructure (ACI).

The Cisco Nexus 9300 platform consists of fixed-port switches designed for top-of-rack (ToR) and middle-of-row (MoR) deployment in data centers that support enterprise applications service provider hosting and cloud computing environments. The switches are Layer 2 and 3 nonblocking 10 and 40 Gigabit Ethernet and Fibre Channel over Ethernet (FCoE)-capable switches with up to 2.56 terabits per second (Tbps) of internal bandwidth.
