Built for Security, IoT, Mobility, and Cloud Advanced persistent security threats, the exponential growth of the Internet of Things (IoT) devices, mobility everywhere and cloud adoption require a network fabric that integrates advanced hardware and software innovations to automate, secure, and simplify customer networks. The goal of this network fabric is to enable customer revenue growth by accelerating business service rollout. The Cisco® Digital Network Architecture (Cisco DNA™) with Software-Defined Access (SD-Access) is the most advanced network fabric to power customer business. Cisco DNA is an open and extensible, software-driven architecture that accelerates and simplifies your enterprise network operations. The programmable architecture frees your IT staff from time-consuming, repetitive network configuration tasks so they can focus instead on innovation that positively transforms your business. SD-Access enables policy-based automation from edge to cloud with foundational capabilities that include: Simplified device deployment Unified management of wired and wireless networks Network virtualization and segmentation Group-based policies Context-based analytics Cisco Catalyst® 9400 Series switches are Cisco's lead modular enterprise switching access and aggregation platform built for security, IoT and cloud. This switch series forms the foundational building blocks for SD-Access, Cisco's leading enterprise architecture. Catalyst 9400 Series switches provide unparalleled investment protection with a chassis architecture that is capable of supporting up to 9 Tbps of system bandwidth and unmatched power delivery for high density IEEE 802.3BT (60W PoE). Redundancy is now table stakes across the portfolio. Cisco Catalyst 9400 Series switches deliver state-of-the-art High Availability (HA) with capabilities like SSO/NSF, uplink resiliency, N+1/N+N redundancy for power supplies. Catalyst 9400 Series switches are enterprise optimized with an innovative dual-serviceable fan tray design, side to side airflow and is closet-friendly with ~16? depth. A single system can scale up to 384 access ports with your choice of 1G copper, 1G fiber, Cisco UPOE® and PoE+ options and up to 192 ports of 10G Fiber and multigigabit options. The platform also supports advanced routing and infrastructure services, SD-Access capabilities and network system virtualization. These features enable optional placement of the platform in the core and aggregation layers of small to medium-sized campus environments.
