Key Features

Extended InfiniBand Reach

The NVIDIA MetroX-3 XC system significantly extends the reach of InfiniBand networks, making it possible to maintain seamless high-performance connectivity across large geographic distances.

By supporting transmission over fiber links up to 40 kilometers, the system removes traditional distance barriers in networking infrastructure

This feature is essential for organizations that operate distributed data centers, need to connect campus environments, or deploy critical infrastructure in remote locations.

Unlike conventional solutions that suffer from high latency and signal degradation over long distances, MetroX-3 XC maintains the native performance advantages of InfiniBand including low latency, high throughput, and consistent packet delivery.

This makes it ideal for latency-sensitive applications such as real-time analytics, AI training, financial transactions, and scientific simulations.

It ensures that InfiniBand capabilities are preserved even across wide area networks (WANs), enabling high-speed interconnectivity without sacrificing performance or reliability.

Long-Haul Data Transmission

One of the most powerful features of the MetroX-3 XC is its support for DWDM (Dense Wavelength Division Multiplexing) technology, which allows multiple data streams to be transmitted simultaneously over a single fiber link by assigning each stream a unique wavelength.

This significantly enhances bandwidth efficiency and allows for more scalable network designs across long distances.

By leveraging DWDM, MetroX-3 XC minimizes the need for additional cabling and infrastructure while maximizing data throughput.

It ensures secure and high-integrity communication between geographically dispersed sites, with minimal signal degradation even across tens of kilometers.

This makes it particularly valuable for use cases like multi-region data center connectivity, metro-scale data replication, and synchronous mirroring of mission-critical workloads.

The system’s DWDM compatibility not only enhances performance but also simplifies network operations, lowers total cost of ownership (TCO), and improves resilience across extended infrastructures.

In-Network Computing

MetroX-3 XC fully supports In-Network Computing by preserving native RDMA (Remote Direct Memory Access) performance across long distances.

This ensures that data can be transferred directly between systems’ memory without involving the CPU, resulting in ultra-low latency and higher efficiency.

With RDMA intact, MetroX-3 XC enables applications to benefit from accelerated compute performance even in multi-site environments.

This is particularly critical for workloads in high-performance computing (HPC), deep learning, and real-time processing, where latency and bandwidth are key performance indicators.

MetroX-3 XC ensures that data centers connected over long distances function as a single unified high-speed network.

The result is accelerated communication, reduced overhead, and improved application responsiveness across distributed systems empowering developers and IT administrators to scale high-performance workloads without compromising on compute speed or accuracy.

Disaster Recovery & High Availability

MetroX-3 XC is a vital component in building highly resilient IT infrastructures.

Its ability to connect primary and secondary data center sites with reliable, high-speed links makes it ideal for disaster recovery (DR) and business continuity (BC) planning.

By maintaining synchronous and asynchronous data replication across distant sites, it ensures that mission-critical data remains safe and recoverable in the event of system failures, power outages, or natural disasters.

Additionally, the system supports redundant paths and fault-tolerant configurations to minimize downtime and ensure continuous service availability.

Whether it’s ensuring 24/7 access to enterprise applications or supporting rapid failover in cloud deployments, MetroX-3 XC is designed to keep business operations running without interruption.

Its ability to deliver low-latency, high-throughput connectivity between backup and production environments makes it indispensable in any organization’s high-availability strategy.
