Cisco N9300 Series Smart Switch Data Sheet

The Cisco N9300 Series Smart Switches transform data-center networking and security by integrating Data Processing Units (DPUs) alongside networking ASICs in a compact form factor. These switches integrate advanced features such as stateful segmentation, and other services with core networking functions, promoting scalable, sustainable, and secure data-center operations. This ensures optimal performance and robust security for next-generation infrastructures while also lowering the total cost of ownership.

Enterprise data-center challenges

Today’s enterprise data centers are facing a multitude of challenges stemming from constantly changing business needs, complex applications, and evolving user expectations. Enterprise data-center teams are increasingly adopting complex hybrid-cloud strategies to meet the changing demands of their businesses and applications. This makes it extremely challenging to secure their critical applications and infrastructure.

The adoption of multi-cloud models and complex application policies forces data-center infrastructure teams to manage security with a fragmented set of tools, including agents, probes, and physical and virtual firewalls. This complex environment makes it prone to errors and opens doors to security breaches. Existing physical firewall appliances are limited in capacity and are not scalable, creating bottlenecks for security as traffic grows. Furthermore, disparate tools hinder SecOps teams' ability to have a unified view of their data-center policies, limiting their access to telemetry and actionable insights, which slows incident response and impacts business continuity. Rising government regulations and the critical need to protect sensitive customer data amid ongoing threats make segmentation an urgent priority.

Solution: Cisco N9300 Series Smart Switches

Modern data centers require a hardware and software solution that offers the flexibility and agility of software-based solutions while ensuring the robustness of physical services appliances. These hyper-distributed data centers need a solution that natively integrates networking and security and other services, is simple and cost-effective to deploy and can automate policy creation and management at scale to ensure uptime and advanced protection at scale.

Data center switches with P4 programmable ASICs and integrated DPUs provide the optimal solution, by bringing the best-in-class hardware acceleration and the flexibility of software-based solutions. By offloading services tasks such as layer-4 segmentation, policy enforcement as well as compute intensive networking services to the data processing units, these switches enable faster threat detection and enhanced network efficiency. Unlike traditional firewalls, the distributed security architecture of these switches provides scalable, distributed policy enforcement across workloads and network nodes. Advanced telemetry and management tools simplify operations while enabling real-time monitoring and actionable insights, making them essential for addressing the complexity and scalability needs of modern data centers.

Cisco N9300 Series Smart Switches enable customers to unlock the value of DPU acceleration through security functions today and other services in the future. First and foremost, Cisco Smart Switches enable customers to integrate network, security, and other functions into a compact fixed form factor. Cisco N9300 Series Smart Switches enable customers integrate network, security, and other services such as Carrier-Grade NAT, IPsec, telemetry, Encapsulated Remote SPAN (ERSPAN), and load balancing into a compact fixed form factor that greatly reduces the total cost of ownership for customers and simplifies operations.

Key benefits of Cisco N9300 Series Smart Switches:

●     Architectural simplicity and scalability: Streamline operations with a unified approach to networking and security. Cisco Nexus^® Dashboard simplifies centralized management and monitoring, while Hypershield fortifies hyper-distributed data centers with scalable and automated security.

●     Consistent policy: Consistent network services and security policy for containers, bare-metal and VMs.

●     Cost optimization: Reduce complexity and operational costs by consolidating networking, security, and telemetry functions into a single physical form factor. This integration lowers hardware, power, and maintenance expenses while enhancing operational efficiency.

●     Unmatched performance: Harness real-time, low-latency processing capabilities powered by DPUs, optimized for hybrid-cloud environments and AI/ML workloads.

●     Scalable, high-speed security: Deliver robust security at scale with multi-terabit speed enforcement of micro segmentation policies. Protect east-west traffic and ensure compliance with modern cybersecurity standards without compromising performance.

●     Make data centers future-ready: Design infrastructure investments with flexibility to support evolving technologies and workloads. Unlock advanced DPU-enabled applications such as firewalling, dynamic segmentation, high-performance load balancing, and real-time telemetry over the next five to seven years, ensuring long-term value and adaptability.

The Cisco N9300 Series Smart Switch family consists of 25G and 100G switches with 800G DPU acceleration. This may be extended to include other form factors, port speeds and services capabilities in the future.

Table 1.        Cisco N9300 Series Smart Switches

Cisco N9300 Series Smart Switches use Cisco^® Silicon One^® E100 ASIC for switching and AMD DPUs for security and other services. This brings together the industry-leading programmability, power efficiency, and flexibility of Cisco Silicon One ASICs and AMD DPUs.

Table 2.        Switching ASIC and DPU hardware capabilities

Cisco N9300 Series Smart Switches support Cisco NX-OS and Nexus Dashboard for network management and a Cisco Hypershield™ on-premises controller for security management. The Cisco Hypershield controller offers an on-premises software appliance that also integrates with Cisco Security Cloud Control, giving customers the flexibility to use the on-premises controller or the Security Cloud Control for configuration and management. NX-OS and Hypershield will be integrated into a single software image to simplify the deployment and will have the ability to upgrade independently to ensure operational flexibility.

Cisco Hypershield is a distributed, Al-native security architecture with a vision to put security wherever it needs to be—in every software component of every application running on the network, server, and public or private cloud deployments. Hypershield uniquely combines security and networking by taking the network security functions that used to come in dedicated boxes and integrating them into the network. It provides Al-powered management that automates security policy lifecycles and security infrastructure upgrades.

Cisco Hypershield with the Cisco N9300 Series Smart switches offers a groundbreaking approach to data center security by integrating advanced network segmentation and zero-trust capabilities directly into the DPU architecture. Hypershield leverages the DPU's ability to offload and accelerate security functions, ensuring real-time stateful Layer-4 segmentation, and policy enforcement without compromising performance. This ensures that sensitive workloads are isolated, protected, and compliant with stringent security standards, all while enabling high-throughput, low-latency communication across the network.
