Selecting advanced PCIe device settings

Procedure
  1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > PCIe Device Configuration > Advanced PCIe Configuration.
  2. Select settings.
    • NVMe PCIe Resource Padding—Configures PCIe resources to support PCIe hot-add for NVMe drives.

      • Normal—Only allocates PCIe resources to devices installed at boot time. PCIe hot-add is not supported.

      • Medium—Allocates additional PCIe resources for each PCIe root port, which might enable a PCIe hot-add event to work without requiring a system reboot to enumerate the device.

      • High—Allocates a maximum amount of PCIe resources to allow for the best chance of supporting a PCIe hot-add event.

    • Maximum PCI Express Speed—When Workload Profile is set to Custom, sets the maximum speed at which the server allows PCI Express devices to operate.

      • Per Port Control

      • PCIe Generation 1.0

  3. Save your settings.
