With 96 ports, the Brocade 6520 provides an aggregate 1,536 Gbps full-duplex throughput. Up to eight ISLs can be combined together in a 128 Gbps framed-based trunk. In addition, exchange-based Dynamic Path Selection (DPS) optimizes fabric- wide performance and load balancing by automatically routing data to the most efficient, available path in the fabric (see Figure 1). This augments Brocade ISL Trunking to provide more effective load balancing in certain configurations. Moreover, the enterprise-class capabilities of this switch yield 40 percent higher performance compared to 10 Gigabit Ethernet (GbE) alternatives at a similar cost. Simplified Management and Robust Network Analytics Brocade Fabric Vision™ technology provides a breakthrough hardware and software solution that helps simplify monitoring, maximize network availability, and dramatically reduce costs. Featuring innovative monitoring, management, and diagnostic capabilities, Fabric Vision technology enables administrators to avoid problems before they impact operations, helping their organizations meet Service Level Agreements (SLAs). Fabric Vision technology includes:

  • Monitoring and Alerting Policy Suite (MAPS): Provides an easy-to-use solution for pre-built, policy-based threshold monitoring and alerting. MAPS proactively monitors the health and performance of the SAN infrastructure to ensure application uptime and availability. By leveraging pre-built, rule-/policy-based templates, MAPS simplifies fabric-wide threshold configuration, monitoring, and alerting. Administrators can configure the entire fabric (or multiple fabrics) at one time using common rules and policies, or customize policies for specific ports or switch elements.
  • Fabric Performance Impact (FPI) Monitoring: Leverages pre-defined MAPS policies to automatically detect and alert administrators to different latency severity levels, and identifies slow drain devices that could impact network performance. This feature uses advanced monitoring capabilities and intuitive MAPS dashboard reporting to indicate various latency severity levels, pinpointing exactly which devices are causing or are impacted by a bottlenecked port.

  • Dashboards: Provides integrated dashboards that display an overall SAN health view, along with details on out-of- range conditions, to help administrators easily identify trends and quickly pinpoint issues occurring on a switch or in a fabric.
  • Configuration and Operational Monitoring Policy Automation Services Suite (COMPASS): Simplifies deployment, safeguards consistency, and increases operational efficiencies of larger environments with automated switch and fabric configuration services. Administrators can configure a template or adopt an existing configuration as a template and seamlessly deploy the configuration across the fabric. In addition, they can ensure that settings do not drift over time with COMPASS configuration and policy violation monitoring within Brocade Network Advisor dashboards.
  • Brocade ClearLink Diagnostics: Ensures optical and signal integrity for Gen 5 Fibre Channel optics and cables, simplifying deployment and support of high-performance fabrics. ClearLink Diagnostic Port (D_Port) is an advanced capability of Gen 5 Fibre Channel platforms.
  • Flow Vision: Enables administrators to identify, monitor, and analyze specific application flows in order to simplify troubleshooting, maximize performance, avoid congestion, and optimize resources. Flow Vision includes: – Flow Monitor: Provides comprehensive visibility into flows within the fabric, including the ability to automatically learn flows and non- disruptively monitor flow performance. Administrators can monitor all flows from a specific host to multiple targets/LUNs, from multiple hosts to a specific target/LUN, or across a specific ISL. Additionally, they can perform LUN-level monitoring of specific frame types to identify resource contention or congestion that is impacting application performance. – Flow Generator: Provides a built- in traffic generator for pre-testing and validating the data center infrastructure—including route verification and integrity of optics, cables, ports, back-end connections, and ISLs—for robustness before deploying applications.
  • Forward Error Correction (FEC): Enables recovery from bit errors in ISLs, enhancing transmission reliability and performance.
  • Credit Loss Recovery: Helps overcome performance degradation and congestion due to buffer credit loss. Brocade Network Advisor Brocade Network Advisor simplifies Gen
