Description
Sophos XGS 6500
The Sophos XGS 6500 is a 2U enterprise firewall designed for organizations that need high network throughput, advanced security inspection, and adaptable connectivity. It forms part of the Sophos XGS 2U Enterprise Edge range and combines a multi-core x86 CPU with an Xstream Flow Processor for hardware acceleration of qualifying workloads.
The appliance provides up to 120 Gbps firewall throughput, 50.75 Gbps IPS throughput, 53.5 Gbps threat protection throughput, and 46.5 Gbps NGFW throughput. It also supports up to 109.8 Gbps IPsec VPN throughput and 16 Gbps Xstream SSL/TLS inspection throughput.
Connectivity
The XGS 6500 includes eight fixed Gigabit Ethernet copper interfaces and twelve 10GbE SFP+ fiber interfaces. Two fixed bypass port pairs are also included.
For additional connectivity, the appliance supports standard Flexi Port and high-density Flexi Port modules. Available options include additional Gigabit copper, Gigabit SFP, 10GbE SFP+, 40GbE QSFP+, bypass, and high-density combinations.
Enterprise Reliability
The XGS 6500 is designed for rack-based enterprise deployments and includes dual internal hot-swappable power supplies. It also uses two 480 GB drives configured as hardware RAID-1, providing storage redundancy for the appliance.
Selection Guide
For High-Speed Firewall Deployment
Choose the XGS 6500 when the environment requires high firewall throughput, substantial concurrent connection capacity, and high-speed 10GbE connectivity.
For 10GbE Connectivity
Use the integrated 12 × 10GbE SFP+ interfaces for fiber-based uplinks and high-bandwidth network connections. Transceivers are sold separately.
For Additional Ports
Review the available Flexi Port modules and select the appropriate copper, fiber, 10GbE, 40GbE, bypass, or high-density module based on the required interface type.
For High Availability
For Sophos Firewall HA deployments, the primary and auxiliary appliances must use the same firewall model. If Flexi Port modules are installed, Sophos also requires the same number of Flexi Ports on both devices.
Always Verify
Confirm the exact hardware revision, supported Flexi Port modules, transceiver requirements, SFOS compatibility, licensing, and deployment requirements before purchasing.
Installation Notes
The Sophos XGS 6500 is a 2U rackmount appliance and uses included sliding rails. Sophos specifies a minimum rack depth of 588 mm and maximum rack depth of 870 mm.
Install the appliance in an appropriate rack with sufficient airflow. Connect the required WAN, LAN, management, and fiber interfaces, then install supported SFP+ or other compatible transceivers where required.
Flexi Port modules should be installed according to the relevant Sophos hardware documentation. Check the supported module list before installation because module compatibility is model-specific.
The appliance has two hot-swappable internal power supplies. Connect power to appropriate redundant power sources where the deployment requires power redundancy.
Best Practices
- Verify the exact XGS 6500 hardware revision before purchasing expansion modules.
- Use compatible Sophos-listed SFP/SFP+/QSFP transceivers.
- Confirm fiber type and optical reach before selecting transceivers.
- Use the dedicated MGMT interface for administrative access where appropriate.
- Maintain adequate airflow around the 2U appliance.
- Use redundant power sources for the two hot-swappable power supplies.
- Document Flexi Port modules and transceiver assignments.
- Maintain consistent hardware and Flexi Port configurations in HA deployments.
- Keep firmware and security signatures updated according to Sophos recommendations.
- Validate throughput requirements against the actual security features enabled in production.
Benefits for IT Teams
The Sophos XGS 6500 provides IT teams with a high-capacity firewall platform that combines security inspection, high-speed interfaces, modular expansion, and hardware redundancy.
Its 10GbE connectivity reduces the need for additional interface conversion in high-speed network environments, while Flexi Port modules allow administrators to adapt the appliance to different network designs. The 2U rackmount form factor, dual power supplies, RAID-1 storage, and enterprise-oriented architecture also support standardized infrastructure deployments.
For distributed organizations, the high IPsec VPN capacity and large concurrent connection capacity provide additional headroom for remote locations and connected users.
Main Benefits
High-Speed Network Security
The XGS 6500 provides up to 120 Gbps firewall throughput.
Benefit: Protect high-volume enterprise traffic without relying solely on CPU-based processing.
High-Speed Fiber Connectivity
Twelve integrated 10GbE SFP+ interfaces provide multiple high-speed fiber connections.
Benefit: Connect the firewall to high-bandwidth aggregation, core, server, and data-center infrastructure.
Flexible Expansion
Flexi Port modules provide additional copper, fiber, 10GbE, 40GbE, bypass, and high-density connectivity options where supported.
Benefit: Adapt the firewall’s interfaces as network requirements change.
Hardware-Accelerated Processing
The XGS architecture combines an x86 CPU with a dedicated Xstream Flow Processor.
Benefit: Qualifying firewall, TLS, and IPsec workloads can benefit from hardware acceleration.
Power Redundancy
Two internal hot-swappable power supplies are included.
Benefit: Replace a failed power supply without designing the deployment around a single internal power source.
Enterprise Scalability
The XGS 6500 supports up to 39.9 million concurrent connections and up to 10,000 concurrent IPsec VPN tunnels.
Benefit: Support large numbers of users, applications, remote sites, and network connections.
Typical Use Cases
1. Enterprise Edge Security
Deploy the XGS 6500 at the enterprise edge to inspect and control large volumes of internet, application, and business traffic.
2. Campus Network Security
Use the high interface density and 10GbE connectivity to connect the firewall with campus aggregation and core infrastructure.
3. Data-Center Connectivity
The 10GbE SFP+ interfaces provide high-speed links for data-center environments and other bandwidth-intensive network architectures.
4. High-Speed VPN Connectivity
Use the high IPsec VPN throughput to support site-to-site and remote connectivity requirements across enterprise locations.
5. Network Segmentation
Use the firewall to establish security boundaries between business networks, server environments, internet-faci6500 ng resources, and other network segments.
6. High-Density Firewall Deployments
Optional Flexi Port modules allow the XGS to expand its interface capacity and reach a maximum port density of up to 68 ports.
