Features and Benefits

Choice at the Core and at the Edge
Brocade DCX Backbones are available in two modular form factors. Built for large enterprise networks, the 14U Brocade DCX has eight vertical blade slots to provide up to 512 Fibre Channel ports using Brocade-branded 4 Gbps or 8 Gbps SFPs. Built for midsize networks, the 8U Brocade DCX-4S has four horizontal blade slots to provide up to 256 Fibre Channel ports.

Both models feature ultra-high-speed Inter-Chassis Link (ICL) ports to connect up to three backbones, providing extensive scalability and flexibility at the network core without using any Fibre Channel ports. At the network edge, organizations can utilize Brocade 8 Gbps switches, Brocade 48000 Directors, or—for complete backbone-class capabilities—the Brocade DCX-4S.

Highest Performance and Scalability
Both Brocade DCX models provide 256 Gbps of bandwidth per slot. When combined with unique Brocade local switching capabilities—data traffic within the same port group does not consume slot bandwidth—the Brocade DCX family provides over four times the performance of competitive offerings. Performance capabilities include:

  • Brocade DCX:
    • Up to 512 ports(equivalent to 576 with ICLs) at 8 Gbps
    • 4.6 Tbps chassis bandwidth
      • 4.1 Tbps Fibre Channel/FICON ports
      • 512 Gbps ICL bandwidth
    • 256 Gbps bandwidth per slot
  • Brocade DCX-4S:
    • Up to 256 ports (equivalent to 288 with ICLs) at 8 Gbps
    • 2.3 Tbps chassis bandwidth
      • 2.0 Tbps Fibre Channel/FICON ports
      • 256 Gbps ICL bandwidth
    • 256 Gbps bandwidth per slot

Flexible Multiprotocol Architecture
Brocade DCX Backbones include a Virtual Fabrics feature that enables partitioning of a physical SAN into logical fabrics and isolation by application, business group, customer, or traffic type. Optional Fibre Channel Integrated Routing alleviates the need for special-purpose blades or routers to connect servers and storage in separate fabrics.

The Brocade DCX family supports 1/2/4/8 Gbps Fibre Channel and FICON, FCIP, and IPFC. To consolidate server connectivity using Data Center Bridging (DCB) and Fibre Channel over Ethernet (FCoE) in open system environments, the Brocade FCOE10-24 Blade enables a high-density, end-of-row chassis configuration.

Plug-In Security and Disaster Recovery Solutions
The Brocade DCX family enables scalable, high-performance, and cost-effective security and disaster recovery solutions through plug-in blades. Brocade FS8-18 Encryption Blades can encrypt data-at-rest at up to 96 Gbps per blade with highly secure 256-bit AES and integrated support for leading key management applications. Brocade FX8-24 Extension Blades extend replication and backup over IP WAN links with the industry’s first and only 10 Gbps FCIP connectivity.

Intelligent Management
To help maximize network performance and reduce operational expense, Brocade Network Advisor provides intuitive system configuration, comprehensive management, and a topology-centric view across Brocade data center solutions. Brocade Network Advisor Enterprise supports both backbone models, while Brocade Network Advisor Professional (bundled) and Brocade Network Advisor Professional Plus support the Brocade DCX-4S.

Simplified Management and Robust Network Analytics
Brocade Fabric Vision technology introduces a breakthrough hardware and software solution that maximizes uptime, simplifies SAN management, and provides unprecedented visibility and insight across the storage network. Offering innovative diagnostic, monitoring, and management capabilities, Brocade DCX Backbones with Fabric Vision technology help administrators avoid problems, maximize application performance, and reduce operational costs. Brocade DCX Backbones support the following Brocade Fabric Vision technology features:

  • Flow Monitor: Provides comprehensive visibility into flows in the fabric, including the ability to automatically learn (discover) flows and non-disruptively monitor flow performance. Users can monitor all flows from a specific host to multiple targets/LUNs or from multiple hosts to a specific target/LUN; monitor all flows across a specific ISL; or perform LUN-level monitoring of specific frame types to identify resource contention or congestion that is impacting application performance.
  • Monitoring and Alerting Policy Suite (MAPS): Provides comprehensive visibility into flows in the fabric, including the ability to automatically learn (discover) flows and non-disruptively monitor flow performance. Users can monitor all flows from a specific host to multiple targets/LUNs or from multiple hosts to a specific target/LUN; monitor all flows across a specific ISL; or perform LUN-level monitoring of specific frame types to identify resource contention or congestion that is impacting application performance.
  • Bottleneck Detection: Simplifies fabric-wide threshold configuration and monitoring. By leveraging pre-built rule/policy-based templates, applying thresholds and alerts to ports is a simple two-step process. Organizations can configure the entire fabric (or multiple fabrics) at one time using common rules and policies, or customize policies for specific ports—all through a single dialog. The integrated dashboard displays an overall switch health report, along with details on out-of-policy conditions, to help administrators quickly pinpoint potential issues.
  • Integration into Brocade Network Advisor: Provides customizable health and performance dashboard views to pinpoint problems faster, simplify SAN configuration and management, and reduce operational costs.
  • Critical diagnostic and monitoring capabilities: Help ensure early problem detection and recovery.
  • Non-intrusive and non-disruptive monitoring on every port: Provides a comprehensive end-to-end view of the entire fabric using capabilities integrated into hardware, allowing sophisticated monitoring without imposing an additional burden on switches with frequent polling activity.

Energy Efficiency and Reliability
Brocade DCX Backbones are highly efficient at reducing power consumption, cooling, and the carbon footprint in data centers. While providing unmatched performance and scale, Brocade DCX Backbones use less than one watt per Gbps—making them five times more efficient than competitive offerings.

To help minimize downtime costs, the Brocade DCX Backbone family builds upon years of innovation and leverages the core technology of Brocade systems performing at greater than 99.999 percent uptime in the world’s most demanding data centers.
