Networking and PCIe
The PowerEdge R640 oers balanced, scalable I/O capabilities, including integrated PCIe 3.0-capable expansion slots. Dell EMC Network
Daughter Cards allow you to choose the right network fabric without using up a valuable PCI slot. You can pick the speed, technology,
vendor, and other options, such as switch-independent partitioning, which allows you to share and manage bandwidth on 10 GbE
connections.
PCIe expansion cards
The PowerEdge R640 system has one standard PCIe connector and four Speededge connectors.
The PowerEdge R640 system has the following four riser cards:
• Right Riser 1A - One x16 PCIe Gen3 for low-prole cards on left side and one x16 PCIe Gen3 for low-prole card on right side –
connected to CPU1—Top and bottom
• Right Riser 1B - One x16 PCIe Gen3 for low-prole card on left side – connected to CPU1—Top and bottom
• Left Riser 2A - One x16 PCIe Gen3 for low-prole cards - connected to CPU2.
• Left Riser 2B - One x16 PCIe Gen3 for full-height cards, may be used for full-height 3/4 length PCIe cards - connected to CPU2.
With all the risers, the PowerEdge R640 system board provides one x8 PCIe Gen3 slot for dedicated storage controller card connected to
the CPU1 and one x8 PCIe Gen3 slot for dedicated NDC connected to the CPU1.
