PLANET is proud to introduce the DCS-7342-32D2X, a Layer 3 32-port 400G QSFP-DD and 2-port 10G SFP+ Managed AI Data Center Switch designed for next-generation data center fabrics where AI servers, GPU clusters, high-speed storage and East-West traffic require massive bandwidth.
Unlike a conventional cloud data center switch that primarily expands the server aggregation backbone, the DCS-7342-32D2X is positioned for AI-scale infrastructure. It provides a high-density 400G switching foundation for AI training, distributed inference, GPU-to-GPU communication, AI storage fabrics, high-performance computing, and 400G spine-leaf architectures.
With 32 x 400G QSFP-DD interfaces, advanced Layer 3 routing, VxLAN/EVPN virtualization, MLAG redundancy, ECMP load balancing, BGP/OSPF/IS-IS routing and carrier-grade management, the DCS-7342-32D2X helps organizations transition from cloud networking to AI-ready data center fabric without requiring an open system NOS such as SONiC.
For environments migrating from existing 100G infrastructure, the 400G QSFP-DD design can also support flexible 400G-to-4 x 100G breakout deployment models, enabling native 400G AI servers and 100G leaf/server connections to coexist in a phased upgrade architecture.
Future-ready AI Data Center Interconnects: Advanced L3 Routing & Virtualization
The DCS-7342-32D2X is a high-performance Layer 3 data center switch engineered for AI-driven, high-speed and scalable environments. With a high-density configuration of 32 x 400G QSFP-DD ports, it serves as a foundation for AI fabric spine, 400G aggregation, high-performance computing and next-generation data center deployments.
Advanced Data Center Overlays: VxLAN & EVPN Integration
To master the complexity of modern cloud infrastructures, the DCS-7342-32D2X integrates hardware-accelerated VxLAN and EVPN to build scalable, high-performance virtualized overlay networks.
Resilient Network Infrastructure via Seamless MLAG Integration
To ensure non-stop network services and maximize bandwidth utilization, the DCS-7342-32D2X supports advanced MLAG (Multi-Chassis Link Aggregation). This technology delivers carrier-grade reliability and architectural flexibility for mission-critical infrastructures.
Carrier-Grade Resilience for High-Scalability Network Environments
PLANET delivers a high-density, carrier-grade switching solution engineered to dominate the rigorous traffic demands of modern scalable networks. By integrating advanced Layer 3 software with next-generation hardware, this platform ensures seamless expansion and unwavering stability.
Intelligent Management & Advanced Security Framework
The DCS-7342-32D2X combines sophisticated automation protocols with robust security architecture to simplify operations and protect critical data paths.
Sustainable Infrastructure: Intelligent Power Management & Green Efficiency
As environmental responsibility becomes a core requirement for modern IT, the DCS-7342-32D2X integrates advanced power-saving technologies without compromising high-performance data center demands.
1-to-4 Port Expansion: 400G to 4 x 100G Breakout Solution
Maximize your hardware investment by transforming a single 400G QSFP-DD port into four independent 100G QSFP28 connections. This professional-grade breakout cable provides the most efficient way to link high-capacity core switches to multiple high-performance servers or storage nodes.
Core Advantages
AI-Ready 400G Fabric for Next-generation Data Centers
As AI workloads continue to reshape data center architecture, network traffic is shifting from traditional North-South application delivery to massive East-West data exchange between GPU servers, high-speed storage systems and compute clusters. The DCS-7342-32D2X is designed to provide the high-bandwidth switching foundation required for AI training, distributed inference, high-performance computing and AI storage fabrics.
With 32 x 400G QSFP-DD ports, the switch can operate as a high-performance AI fabric spine, a 400G aggregation switch, or a flexible migration platform through 4 x 100G breakout. This allows organizations to build scalable spine-leaf networks for both native 400G AI servers and existing 100G infrastructure.
