Fleet-wide fabric visibility. Marvell RELIANT delivers actionable, real-time insight
into interconnect health at the equipment, rack, row and data center.

RELIANT monitors the range of Marvell interconnect technologies—including coherent digital signal processors (DSPs), COLORZ® data center interconnect modules, PAM4 DSPs, co-packaged optics, active electrical cable (AECs) DSPs, PCIe retimers, and active copper cables equalizers—and can be integrated with other telemetry dashboards for comprehensive visibility.

RELIANT is now available to customers and partners, and Marvell will showcase it at OFC, taking place March 17–19 in Los Angeles, California.

RELIANT: Multiple Ways to View Data

The dashboard below, for instance, shows a live operating status of 70 racks containing 22,656 modules. Of the total, 70 modules (0.3%) indicate a critical issue:

Users can then drill down to the row, rack and individual server level:

RELIANT also lets users isolate and analyze individual interconnect parameters. The image below shows forward error correction performance across a fleet. Interconnect data can be filtered by specific rows or racks, health rating (healthy, warning, critical), connection type (optics, ZR, AEC, etc.), parameter (FEC, bit error rate, signal-to-noise ratio), time period (up to 90 days) and refresh rate (5 seconds to 5 minutes).

Here’s a focused view of the data, highlighting only the critical interconnect warnings across the fleet. Selecting any column reveals more detailed information for the corresponding links:

The interface can also be customized to suit the preferences of employees and organizations:

RELIANT features include:

• Real-time link monitoring for early issue detection
• Predictive link status analytics to prevent downtime
• Automated diagnostics and tuning to optimize system performance
• Unified system visibility across optics, DPSs, switch silicon, PCIe retimers, NICs and modules
• Scalable data ingestion for large, distributed deployments
• API/SDK-based integration into customer NMS and data lakes

A New Offering with Years of Experience

RELIANT is the culmination of two interconnect software technologies pioneered over a decade ago that Marvell has steadily continued to refine: a telemetry platform specifically designed for optical DSPs and a telemetry visualization suite to help engineers more readily engage with the data. Marvell has primarily used these capabilities to design and debug optical DSPs and other silicon during product development. RELIANT effectively extends and enhances these capabilities for a new range of use cases and customers.

Partners can also access RELIANT and other telemetry tools in the Marvell Cloud Interoperability Lab to test modules, cables and others across a wide range of customized configuration scenarios with leading XPUs, CPUs, NICs, servers, switches, optical modules and other critical infrastructure devices. Collaboration in the lab enables Marvell and its partners to comprehensively validate technologies, significantly accelerate qualification and deployment timelines, and give data center operators greater confidence from the first plug-in.

In AI environments, time is a critical resource. RELIANT delivers real-time visibility and rapid issue resolution, empowering customers to address emerging problems immediately and apply those learnings to drive ongoing infrastructure optimization. Marvell will share additional updates as we advance our technology initiatives focused on infrastructure efficiency and performance.
