7 PCIe Infrastructure

Instead of using traditional I/O modules for Fabric B or Fabric C, Dell has designed the PowerEdge

VRTX to use PCIe slots using two PCIe switches — one for Fabric B and one for Fabric C. Each PCIe

switch ties into one of the two mezzanine cards on the server nodes.

The Fabric B PCIe switch provides connectivity to the following:



PCIe slot 3



PCIe slot 5



PCIe slot 6



PCIe slot 7



PCIe Slot 8



Shared PowerEdge RAID Controller (SPERC)

The Fabric C PCIe switch provides connectivity to the following:



PCIe slot 1



PCIe slot 2



PCIe slot 4



PCIe slot 5

The PCIe slots are non-shared and thereby dedicated to one server node within the PowerEdge

VRTX system. The PCIe slots can be reassigned to a different server through the CMC as needed.

Each slot is capable of being exclusively assigned to any server node, although it does require

powering the server node off. You can assign up to four PCIe slots to one server node.

VRTX supports the following PCIe expansion cards.



AMD FirePro™ W7000
