Comprehensive Product Overview

The Brocade G630 (BR-G630-96-32G-R) is a flagship Gen6 FC switch designed to address the most demanding storage networking requirements of today’s dynamic data centers. As part of Broadcom’s Brocade Gen6 portfolio, it builds on 20+ years of FC innovation to deliver unmatched performance, scalability, and reliability for NVMe and traditional SCSI storage environments.

Housed in a 2U rack-mountable chassis, the G630 provides 96 active 32Gbps SFP+ ports (auto-sensing 4/8/16/32G) and 8x128Gbps QSFP+ ports (4×32G, auto-sensing 4×4/8/16/32G) It features a non-blocking shared-memory architecture with ultra-low latency (<780ns local switching) to support high-IOPS flash arrays and NVMe-oF workloads.

A key differentiator is its Ports on Demand (PoD) scalability: start with 48 base ports and activate up to 128 ports (96 SFP+ + 8 QSFP+) via license upgrades, eliminating costly hardware refreshes. The switch runs on Brocade Fabric OS (FOS) v8.2.0+, supporting advanced fabric services, automation, and security features.

With dual hot-swappable redundant power supplies, three hot-swappable fans, and port-side exhaust cooling, the G630 ensures carrier-grade reliability and continuous operation. It seamlessly integrates into existing Brocade fabrics, enabling gradual migration to NVMe while protecting investments in legacy infrastructure.

Frequently Asked Questions (FAQ)

Q1: What is the difference between BR-G630-48-32G-R and BR-G630-96-32G-R?

A: The BR-G630-48-32G-R has 48 active SFP+ ports (base) + 8 QSFP+ ports, scalable to 96 SFP+ ports. The BR-G630-96-32G-R (this model) has 96 active SFP+ ports (factory-activated) + 8 QSFP+ ports, scalable to 128 ports total.

Q2: Is the G630 compatible with older Brocade switches (e.g., G620, G720)?

A: Yes. The G630 runs FOS v8.2.0+ and interoperates with Brocade Gen5 (16Gbps) and Gen6 (32Gbps) switches (G620, G720, etc.) in the same fabric. It supports seamless ISL connections at 16Gbps or 32Gbps.

Q3: Can I mix NVMe and SCSI devices on the same G630 fabric?

A: Absolutely. The G630 supports concurrent NVMe and SCSI traffic on the same fabric. You can gradually migrate from SCSI to NVMe without disrupting existing workloads..

Q4: What is the maximum distance supported by 32Gbps SFP+ transceivers?

A: 32Gbps SWL (850nm): Up to 100m (OM4 fiber) / 50m (OM3 fiber). 32Gbps LWL (1310nm): Up to 10km (single-mode fiber). 32Gbps ELWL (1550nm): Up to 25km (single-mode fiber)

Q5: Does the G630 support FICON for mainframe environments?

A: No. The G630 is optimized for open systems (x86, virtualization, flash storage) and does not support FICON (mainframe connectivity). For mainframe environments, consider the Brocade G730 or FICON-enabled switches.

Q6: How do I activate additional ports with PoD licenses?

A: PoD licenses are activated via FOS CLI or Brocade Network Advisor (BNA). After purchasing a license key, enter it into the switch to activate the desired number of ports (24-port SFP+ or 32-port QSFP+). Activation is non-disruptive and requires no chassis reboot.
