(a) Advanced PCIe Configuration Menu
When you select
System Configuration
>
BIOS/Platform Configuration (RBSU)
>
PCIe Device Configuration
>
Advanced PCIe Configuration
from the System Utilities, the
Advanced PCIe Configuration
menu appears.
For details about the options, see the table below.
Option
Parameter
Description
NVMe PCIe Resource
Padding
[Normal]
Medium
High
Use this option to configure PCIe resources to
support PCIe hot-add for NVMe drives. When Normal
is selected, PCIe resources are only allocated to
devices installed at boot time, and PCIe hot-add is
not supported. When Medium is selected, additional
PCIe resources are allocated for each PCIe Root
Port, which might enable a PCIe hot-add event to
work without requiring a system reboot to enumerate
the device. When High is selected, a maximum
amount of PCIe resources are set aside to allow for
the best chance of supporting a PCIe hot-add event.
Maximum PCI Express
Speed
[Per Port Control]
PCIe Generation 1.0
You can only configure this option if the Workload
Profile is set to Custom. If a PCI Express device does
not run properly at its optimal speed, lowering the
speed at which the device is running can address this
issue. This option enables you to lower the maximum
PCI Express speed at which the server allows PCI
Express devices to operate. You can also use it to
address issues with problematic PCI Express
devices. Setting this value to Maximum Supported
configures the platform to run at the maximum speed
supported by the platform or the PCIe device,
whichever is lower.

Select this option to enable or disable PCI devices.
PCIe Link Speed
[Auto]
PCIe Generation 1.0
Use this option to configure the PCIe Link Speed for
the selected device. When configured for Auto, the
selected device trains at the maximum supported
speed of the PCIe link. When configured for PCIe
Generation, the selected device trains at a maximum
of PCIe Generation 1 linkspeed.
