ADVANCED FEATURES:

High-Performance, Low-Latency Switching Fabric:

The SN2201 delivers 448 Gb/s non-blocking switching capacity and 331 Mpps forwarding rate across all 48 × 25 GbE access ports and 8 × 100 GbE uplinks. Ultra-low latency (~300 ns) ensures minimal delay for time-sensitive workloads, making it ideal for network switch, hub switch, and Ethernet switch deployments. Deep dynamic buffers and a large MAC table handle traffic bursts and high-volume transfers without packet loss, supporting AI/ML, HPC, virtualization, and cloud applications. This ensures smooth and predictable performance for real-time analytics, high-performance computing, and storage replication workloads, providing maximum reliability for enterprise-grade networks. It also reduces jitter for latency-sensitive applications such as financial trading platforms, video streaming, and high-speed databases, guaranteeing consistent throughput under heavy load.

Advanced Layer 2 & Layer 3 Routing and Network Segmentation:

Supports static routing, OSPF, BGP, VRF-lite, and ECMP. VLAN support up to 4,000 allows large-scale enterprise, multi-tenant, and cloud environments to operate efficiently. Optimised traffic distribution and predictable latency ensure stable, secure non-PoE switch operations. Advanced multicast and routing features enable seamless integration with complex data centre topologies, allowing administrators to segment traffic for compliance, security, and multi-service deployments without impacting performance. Additionally, the SN2201 provides efficient path selection and route convergence for dynamic workloads, supporting cloud-native applications and multi-site connectivity.

Stacking and Multi-Chassis Link Aggregation (MLAG):

Active-active MLAG enables multiple switches to operate as a single logical unit for redundancy, load balancing, and automatic failover. High-speed interconnects provide scalable bandwidth and seamless traffic forwarding. Ideal for powered switch deployments requiring horizontal expansion without disruption. This feature ensures continuous availability during maintenance or hardware upgrades, while also optimising bandwidth usage for high-demand applications such as virtualization clusters and distributed storage systems. MLAG also simplifies network management, reducing operational complexity and enhancing reliability across large-scale deployments with minimal manual configuration.

Open Networking Flexibility (ONIE-Compatible):

Fully compatible with Mellanox Onyx, Cumulus Linux, and SONiC, the SN2201 allows deployment of open networking and software-defined networks (SDN). Operators can choose their preferred NOS, automate operations, monitor network health, and integrate with orchestration platforms, providing maximum flexibility for Ethernet switch and power over Ethernet switch deployments. Open networking also allows testing new software features and scaling networks without vendor lock-in, helping IT teams innovate and deploy custom network policies safely. It supports rapid adaptation to new protocols and SDN integrations, enabling future-proof deployments and advanced automation across enterprise and cloud networks.

Energy Efficiency & Fresh-Air Compliance:

Incorporates IEEE 802.3az Energy Efficient Ethernet (EEE) technology, reducing idle power usage. Variable-speed, hot-swappable fans adjust based on traffic and temperature for energy-efficient cooling. Fresh-air compliant design enables deployment in office closets, distributed campuses, or standard data centres without specialised HVAC. This energy-conscious design reduces operational costs and supports environmentally friendly practices, while keeping acoustic noise low for quieter network rooms or office racks. It also helps organisations meet sustainability goals and reduces cooling requirements in dense rack installations.

Redundant, Serviceable Hardware:

Dual hot-swappable AC power supplies and N+1 fan redundancy provide continuous operation. Front-to-back and back-to-front airflow options allow flexible deployment in diverse racks.
