Which Is the PCIe* Port to Plug In My Intel® RAID Controller according to the Number of Processors Installed on the Server?

Unable to determine which mode and PCIe* port needs to be connected, since the server is not detecting it with one processor configuration

Section named PCIe* Add-in Card Support describes which PCIe* 3.0 is controlled by each processor

Use the PCIe 3.0 Port #5 or #6 since they are handled by CPU #1 and the server will be able to detect the add-in card with one processor installed only.

Use the PCIe 3.0 Port #1 to #4 since they are handled by CPU #2 and the server will be able to detect the add-in card with the two processors installed.

• Slot 1: PCIe* 3.0 x8 (x8 electrical) handled by CPU2
• Slot 2: PCIe* 3.0 x16 (x16 electrical) handled by CPU2 (riser capable)
• Slot 3: PCIe* 3.0 x8 (x8 electrical) handled by CPU2
• Slot 4: PCIe* 3.0 x16 (x16 electrical) handled by CPU2
• Slot 5: PCIe* 3.0 x8 (x8 electrical) handled by CPU1
• Slot 6: PCIe* 3.0 x16 (x16 electrical) handled by CPU1 (riser capable)

Additionally, section named Riser Card Support

PCIe* slots 2 and 6 are both capable of supporting riser cards. Each x16 riser slot supports standard x16 PCIe* connector Pin-outs, and they also include two 100-Mhz clocks and Riser_ID bits (to provide link width information to the system BIOS). Each of the designated riser slots can support riser cards with the following PCIe* add-in card slot configurations:

• x16 riser with two x4 PCIe* slots
• x16 riser with one x4 PCIe* slot and one x8 PCIe* slot
• x16 riser with two x8 PCIe* slots
• x16 riser with one x16 PCIe* slot
