Data Center Switches

By unifying storage, data networking, and network services, Cisco Unified Fabric delivers architectural flexibility and consistent networking across physical, virtual, and cloud environments.

Cisco Unified Fabric

Unified Fabric is a holistic network architecture comprising switching, security, and services that is designed for physical, virtual, and cloud environments. It uniquely integrates with servers, storage, and orchestration platforms for more efficient operations and greater scalability.

Cisco Application Centric Infrastructure

Application Centric Infrastructure (ACI) is a holistic architecture with centralized automation and policy-driven application profiles. ACI delivers software flexibility with the scalability of hardware performance.

Key characteristics of ACI include:

  • Simplified automation by an application-driven policy model
  • Centralized visibility with real-time, application health monitoring
  • Open software flexibility for DevOps teams and ecosystem partner integration
  • Scalable performance and multitenancy in hardware

An ACI-based network is deployed, monitored, and managed in a way that supports DevOps and rapid application change. ACI reduces complexity and offers a common policy framework to automate provisioning and managing of resources.
