Comprehensive Product Overview

The Brocade BR-G620-48-32G-R (part of the G620 series) is a next-generation storage networking switch engineered to address the demands of hyper-scale virtualization, large NVMe flash deployments, and complex cloud environments. As a Gen 6 Fibre Channel solution, it supports 32Gbps line speeds with auto-sensing for 4/8/10/16/32G port speeds, ensuring backward compatibility with legacy and modern storage devices.

This switch comes with 48 pre-activated 32G SFP+ ports (including 48x 32G SWL transceivers) and can scale up to 64 ports via license upgrades (adding 4 Q-Flex QSFP ports). The Q-Flex ports support 4×32Gbps or 128Gbps aggregated bandwidth, enabling high-speed inter-switch links (ISLs) and simplified fabric expansion.

With a non-blocking architecture, 2 Tb/s aggregate bandwidth, and support for up to 6,000 active nodes, the BR-G620-48-32G-R delivers enterprise-grade performance for large-scale deployments. It also features Brocade Fabric Vision technology for built-in monitoring, diagnostics, and analytics, reducing management complexity and operational costs.
