Bottleneck Analysis:
In this configuration, the primary bottleneck under heavy load is typically the RAID 5 storage array. While providing data redundancy, RAID 5 incurs a performance penalty during write operations. Upgrading to an all-flash NVMe storage array would significantly improve performance, particularly for I/O-intensive applications. Network bandwidth can also become a limiting factor for applications requiring high network throughput. The PCIe bus can become saturated with multiple high-bandwidth devices installed (e.g., multiple GPUs, high-speed NICs). Storage Performance
