Slot Bifurcation

Auto Discovery Bifurcation Settings

Allows BIOS to dynamically scan for PCIe devices rather than relying strictly on system slot definitions.

Platform Default Bifurcation Strictly follows the system slot definitions when configuring each PCIe slot.
Auto Discovery of Bifurcation Analyzes the installed PCIe cards and determines the correct configuration for each slot. This may include bifurcation of the slot for multiple devices.
Manual Bifurcation Control Allows the user to override bifurcation settings for each slot.
CAUTION: Improper configuration of the PCIe slots can prevent the system from functioning properly.
The number of slots available in the OpenManage Server Administrator UI varies depending on the number of slots that are utilized in the server. The slots are structured numerically as Slot 1 Bifurcation, Slot 2 Bifurcation and so on. The maximum limitation depends on the number of slots available in the server.

The available slot bifurcation options are as mentioned below:

  • x4 Bifurcation
  • x8 Bifurcation
  • x16 Bifurcation

The slots can also be configured in combinations as mentioned below:

  • x4 x4 x8 Bifurcation
