PCIe connectivity is integrated with the processor in that the number of processors in a system
impacts the number of PCIe slots and the bandwidth of each PCIe slot. The PowerEdge R620 offers
a two-slot option (4-, 6-, and 8-drive bay chassis only) and a three-slot option.
For an R620 system with one processor, one two-slot option is available:
Two PCIe x16 slots with one x16 bandwidth and one x8 bandwidth
For an R620 system with two processors, two slot options are available:
Two PCIe x16 slots, both slots with x16 bandwidth
Three PCIe x16 slots with two x16 bandwidth and one x8 bandwidth
Table 18 lists the details of the PCIe slot options.
