Determine the Real Speed of Your Server<\/strong><\/h2>\n

Every storage system is only as fast as its slowest component. Our Bottleneck Analyzer<\/b> tool allows you to precisely identify the speed limits of your storage chain, from your RAID arrays to your network interface card (NIC).<\/p>\n

Don’t rely solely on the theoretical throughput of your RAID! The actual data transfer rate (in MB\/s<\/b> or Gbps<\/b>) is often throttled by critical elements such as the PCIe Bus<\/b> or your controller\u2019s bandwidth.<\/p>\n

Why Use This Tool?<\/strong><\/h3>\n
    \n
  • \n

    Identify Limitations:<\/b> Determine if performance is being held back by the disks, the RAID controller, the PCIe bus<\/b> (generation and lanes), or the network<\/b> connection (e.g., 10GbE).<\/p>\n<\/li>\n

  • \n

    Hardware Optimization:<\/b> Plan your upgrades effectively. If your RAID controller can deliver 8,000 MB\/s, but your PCIe 3.0 x8<\/b> link only supports 4,000 MB\/s, you are wasting potential performance and money.<\/p>\n<\/li>\n

  • \n

    Real-World Performance:<\/b> Get a realistic estimate of the maximum throughput your configuration can achieve in a production environment.<\/p>\n<\/li>\n<\/ul>\n

    How Does the Analysis Work?<\/strong><\/h3>\n

    Enter the maximum throughput for each of your main components (RAID, Controller, Bus, and Network). Our bottleneck analyzer<\/b> evaluates the maximum sequential throughput of every link in the chain and reveals which one represents your bottleneck. This ensures you invest in the right components for your infrastructure.<\/p>\n

    Use this tool before your next upgrade to ensure all components of your infrastructure are correctly sized for the expected performance.<\/p>\n
