PCIe slot mapping from compute sleds mapped to storage sleds
In PowerEdge FX2s enclosure configurations that support storage sleds mapped to compute sleds, the PCIe slots map only to
the compute sleds. When storage sleds are installed in the enclosure, the PCIe slots mapped to these bays are automatically
reassigned to the compute sleds installed in the upper bays of the enclosure. The PCIe slot reassignment feature enables
you to reassign the PCIe slots from compute sleds in the lower bays to the compute sleds in the upper bays. The PCIe slot
reassignment feature applies to enclosure configurations with or without storage sleds. You can enable or disable the PCIe
reassignment option by using the CMC web interface, CMC WSMAN, or RACADM. For more information, see the PowerEdge
FX2/FX2s CMC User’s Guide and the Dell Chassis Management Controller for PowerEdge FX2/FX2s RACADM Command Line
Reference Guide at Dell.com/esmmanuals.
The PCIe slots are mapped to compute sleds in the following manner:
● Four-bay chassis with two half-width compute sleds and two storage sleds—Each half-width compute sled is mapped to
four PCIe slots.
● Four-bay chassis with one half-width compute sled and three storage sleds—The half-width compute sled is mapped to
eight PCIe slots.
● Three-bay chassis with one full-width compute sled and two storage sleds—The full-width compute sled is mapped to eight
PCIe slots.
● Six-bay chassis with four quarter-width compute sleds and two storage sleds—Each quarter-width compute sled is mapped
to two PCIe slots.
