How Can I Optimize The Performance Of Our Existing Fibre Channel Over Ethernet (FCoE) Infrastructure In Our Data Center To Support The Increased Storage Demands Of Our New Virtual Desktop Infrastructure (VDI) Deployment, While Also Ensuring Seamless Integration With Our Existing Brocade DCX Backbone And Minimizing The Need For Costly Upgrades To Our Existing Cisco Nexus 5000 Series Switches?

To optimize your FCoE infrastructure for the VDI deployment, follow this structured approach:

  1. Network Configuration and Optimization:

    • Link Aggregation: Implement link aggregation (e.g., LACP) to combine multiple ports, increasing bandwidth and redundancy.
    • Traffic Prioritization: Configure QoS policies on both Brocade and Cisco switches to prioritize storage traffic, reducing latency.

  2. Enable Advanced Ethernet Features:

    • Data Center Bridging (DCB): Activate DCB with PFC and ETS to enhance traffic management and congestion control.
    • Jumbo Frames: Ensure all devices support jumbo frames to reduce overhead, checking compatibility across the network.

  3. Monitoring and Management:

    • Network Monitoring: Use tools like Brocade Network Advisor and Cisco DCNM to identify bottlenecks and optimize traffic flow.
    • Fabric Optimization: Ensure FSPF is optimized on Brocade devices for efficient routing.

  4. Cisco Nexus 5000 Configuration:

    • Zoning and VSANs: Review and optimize zoning configurations to isolate and streamline storage traffic.

  5. Firmware and Software Updates:

    • Regularly update firmware on both Brocade and Cisco devices to benefit from performance improvements and new features.

  6. Load Balancing and Multipathing:

    • Implement load balancing and multipathing to distribute traffic efficiently, avoiding single points of failure.

  7. VDI-Specific Considerations:

    • Optimize storage systems, possibly using SSDs, to reduce network load.
    • Plan for peak usage scenarios, ensuring scalability and robustness during high-demand periods.

  8. Testing and Validation:

    • Conduct a proof of concept to test optimizations, ensuring they meet performance requirements without impacting the live environment.

By systematically addressing these areas, you can enhance your FCoE infrastructure's performance, supporting the VDI deployment efficiently without major upgrades.
