Changing application environments are creating new demands on the IT infrastructure that supports them. With application workloads deployed across a mix of virtualized and nonvirtualized server and storage infrastructure, you require a network infrastructure that provides consistent connectivity, security, and visibility across a range of bare-metal, virtualized, and cloud computing environments. For example:
- Application instances are created dynamically, so provisioning, modification, and removal of application network connectivity also need to be dynamic.
- Business units demand accelerated application deployments, so IT departments must provide a shared IT infrastructure that addresses time-to-market needs and provides a positive return on investment (ROI).
- When organizations deploy a mix of custom, open-source, and off-the-shelf commercial applications, IT departments must manage security and quality of service (QoS) for environments that support multitenancy.
- Applications are transitioning to a less monolithic, scale-out, multinode model. The IT infrastructure that supports this model must scale with the speed of business and support both 1, 1, 25, 4, 5 and 1 Gigabit Ethernet connectivity.
The Cisco Nexus® 9 Series Switches include both modular and fixed-port switches that overcome these challenges with flexible, agile, low-cost Cisco® Application Centric Infrastructure (Cisco ACI™).
The modular Cisco Nexus 954, 958, and 9516 Switches are Cisco ACI spine devices enabled by nonblocking 1 and 4 Gigabit Ethernet line cards, supervisors, system controllers, and power supplies.
