 Boot from SAN (iSCSI, FCoE) configuration for networking devices through the USC
PCIe expansion
PCIe slots
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 (available with the 4-, 6-, or 8-drive bay chassis only) and a three-slot option (this
is the only option on the 10-drive bay chassis, but available also with the 4-, 6-, and 8-drive bay
chassis).
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.
