Is It Possible to Use All the Peripheral Component Interconnect Express* (PCIe*) Lanes of the Intel® Server Board S2600WF with One Processor?

Environment

OS Independent family

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Summary

PCIe* add-in card support

Description

Unable to determine if using only one CPU opens up all PCIe* lanes on the S2600WFTR board.

Resolution

The server board provides three riser card slots identified as: Riser Slot #1, Riser Slot #2, and Riser Slot #3. The PCIe bus lanes for each riser card slot is supported by each of the two installed processors.

  • Riser Slot #1: X24 PCIe* 3.0
    • X16 PCIe* - CPU #1
    • X8 PCIe* - CPU #2
  • Riser Slot #2: X24 PCIe* 3.0
    • X24 PCIe* - CPU #2
  • Riser Slot #3: X12 PCIe* 3.0
    • X8 PCIe* - CPU #2
    • X4 PCIe* - DMI

Note: A dual processor configuration is required when using Riser Slot #2 and Riser Slot #3, as well as the bottom add-in card slot for 2U riser cards installed in Riser Slot #1.
