7 Networking and PCIe The Dell PowerEdge R820 offers balanced, scalable I/O capabilities, including integrated PCIe 3.0 capable expansion slots. Dell Select Network Adapters, Dell’s network daughter cards, let you choose the right network fabric without using up a valuable PCI slot. Pick the speed, technology, vendor and other options such as switch independent partitioning, which lets you share and manage bandwidth on 10GbE connections.
Only 10GbE ports have switch independent partitioning support. The maximum number of partitions supported is four (two partitions per 10GbE port). 1GbE ports do not support switch independent partitioning. Only 10GbE ports have DCB support. Only 10GbE ports have ISCSI TLV support. PowerEdge R820 Technical Guide...
The R820 provides expanded PCIe slot capability over the previous servers. This is made possible by the 40 PCIe lanes available from each processor in the system. Dell designed the R820 to be PCIe 3.0-compliant in order to take full advantage of the processor capabilities.
