24 PowerEdge R320 Technical Guide7 Networking and PCIeThe Dell PowerEdge R320 offers balanced, scalable I/O capabilities, including integrated PCIe 3.0capable expansion slots. The R320 supports up to 2 PCIe slots.Embedded NIC controllerThe R320 system board has one embedded NIC controller. The Broadcom 5720 Gigabit NIC chip isconnected to the platform controller hub through a PCIe 2.0 x2 link.The Broadcom 5720 is a 14 th generation 10/100/1000Base- T Ethernet LAN controller solutionsuitable for high- performance server applications. The Broadcom 5720 combines dual triple- speedIEEE 802.3 compliant Media Access Controllers (MACs) with dual 10/100/1000 Ethernet transceivers(PHYs), selectable individually per port, a network controller- sideband interface (NC- SI), and anon- chip memory buffer in a single device. The device provides a PCIe 2.1- compliant interface,which operates at 5GT/s or 2.5GT/s x2 link width.PCIe expansionThe R320 provides expanded PCIe slot capability over the previous servers. This is made possible bythe 40 PCIe lanes available from each processor in the system. Dell designed the R320 to be PCIe3.0- compliant in order to take full advantage of the processor capabilities.PCIe slotsPCIe connectivity is integrated with the processor and chipset. Table 14 lists the slot configurationsfor the R320.Table 14. PCIe slot configurationsOne processorPCIe slot 1 PCIe x8 connector with x4 bandwidth; half- length, half- height, 2.0PCIe slot 2 PCIe x16 connector with x16 bandwidth; half- length, full- height, 3.0Storage slot Storage slot for PERCs H310 or H710PCIe expansion cardsThe R320 supports a variety of PCIe expansion cards. Table 15 lists the supported add- in NICs andHBAs for the R320.
